Under-Eye Wrinkles: What Causes Them and How to Treat Them
Under-eye wrinkles are one of the most common skincare concerns - and one of the earliest visible signs of ageing for most people. The skin beneath your eyes is approximately 0.5mm thick, compared to roughly 2mm across the rest of your face. That difference matters. It means the periorbital area has less structural support, lower baseline collagen density, and far less tolerance for the daily stressors - UV exposure, movement, dehydration - that gradually etch lines into the surface.
If you have noticed fine lines forming beneath your eyes, you are not imagining things, and you are not too late. Under-eye wrinkles develop through a combination of factors that are well understood, which means they are also addressable with the right approach. Fine lines and deeper wrinkles are different stages of the same process - and both respond to targeted ingredients applied consistently over time.
This article covers everything you need to know: what actually causes under-eye wrinkles, how to prevent further damage from happening, which ingredients are most effective at treating them, how to build a practical morning and evening routine, and how to tell the difference between wrinkles and dark circles. By the end, you will have a clear, actionable plan - not a vague list of product suggestions, but a real understanding of what your skin needs and why.
The right approach, applied consistently, makes a measurable visible difference. Here is where to start.
What Actually Causes Under-Eye Wrinkles
To treat under-eye wrinkles effectively, it helps to understand what is actually happening beneath the surface. This is not about creating anxiety - it is about knowing your target. The causes of under-eye wrinkles are well documented, and each one points directly toward a treatment strategy.
Collagen and Elastin Loss: The Core Structural Change
Collagen is the protein that gives skin its firmness and bounce. Elastin is the fibre that allows skin to return to its original position after being stretched or compressed. Together, they form the structural scaffolding that keeps skin smooth and taut.
The problem is that collagen production begins slowing from the mid-to-late twenties onward - and the periorbital area starts at a disadvantage. The skin beneath the eyes has a lower baseline collagen density compared to the rest of the face. So when collagen production naturally declines and existing fibres begin to break down, the under-eye zone is often the first place that structural change becomes visible.
As collagen and elastin degrade, skin loses its ability to spring back from compression and repeated movement. Lines that were once temporary - the kind that appear when you squint and disappear when you relax - begin to linger. Over time, they deepen. This progression from surface-level fine lines to more established wrinkles is not inevitable at any particular pace, but it is universal. The difference lies in how quickly it happens, and that is where lifestyle, sun protection, and actives make a real impact.
UV Damage: The Fastest Accelerator
If there is one external factor most responsible for premature under-eye wrinkles, it is UV exposure. UVA rays - the ones that penetrate through glass and remain present on overcast days - reach the dermis directly and break down collagen and elastin fibres through a process called photoageing. Unlike the gradual collagen loss that comes with age, UV-induced damage is cumulative and, to a significant degree, preventable.
The under-eye area is among the most under-protected zones on the face. People routinely apply SPF to their cheeks and forehead while neglecting the delicate periorbital skin - partly because it is a small area, and partly because many sunscreens sting near the eyes. But even low-level daily UV exposure compounds over months and years, quietly accelerating the breakdown of the very collagen structures that keep this thin skin smooth. Understanding how SPF protects against UV damage is one of the most important things a person can do for their skin’s long-term appearance.
Repeated Facial Movement: The Mechanical Cause
The orbicularis oculi is the circular muscle that surrounds the eye and controls blinking, squinting, and the expressions associated with smiling and emotion. It is one of the most active muscles on the face - contracting thousands of times every single day without pause.
Every contraction compresses the overlying skin. Over time, those repeated compressions etch lines into the surface - particularly in areas where the skin is thinnest and least supported. The crow’s feet that develop at the outer corners of the eyes are the most familiar result of this process, but the fine lines that appear directly beneath the eye form through the same mechanism. This is a mechanical reality of having a face that moves and expresses - it is not something to eliminate, but it is something that targeted skincare can meaningfully offset.
Dehydration: The Misunderstood Factor
Dehydration is frequently conflated with dryness, but they are distinct concerns. Dehydration refers to a lack of water in the skin, not a lack of oil. And while dehydration does not cause structural wrinkles, it significantly worsens their appearance - and can create surface-level lines that look like early wrinkles but are actually reversible.
When skin lacks adequate water content, it loses plumpness and surface tension. Fine lines become more pronounced, and the overall texture looks duller and less smooth. Applying a hydrating ingredient - specifically a humectant like hyaluronic acid - draws water into the skin and temporarily restores that plumpness. For many people, improving hydration produces a visible improvement in under-eye appearance within days. It is not a structural fix, but it is an important piece of the picture. You can read more about what dehydrated skin looks like and how to address it.
Skin Thinning Over Time
The periorbital skin does not just start thin - it continues to thin with age. The subcutaneous fat layer beneath the eye gradually redistributes and reduces, increasing translucency and making the skin even more vulnerable to compression and movement. Blood vessels become more visible beneath the surface, and the skin’s capacity to recover from daily stressors diminishes. This thinning process is part of why under-eye concerns tend to compound with age rather than plateau.
Fine Lines Versus Deeper Wrinkles: Understanding the Difference
Fine lines are early, shallow changes - typically surface-level and often significantly influenced by dehydration and the mechanics of expression. They are more responsive to topical ingredients, particularly hydrating actives and early retinoid use. Deeper wrinkles represent structural changes that have set into the dermis over time. They are still improvable with the right ingredients applied consistently, but the timeline is longer and the expectations need to be realistic. Knowing which you are dealing with helps you calibrate your routine and understand what results to expect and when.
With the causes clearly mapped, the most logical next step is prevention - stopping further damage before it compounds what is already there.
How to Prevent Under-Eye Wrinkles Before They Deepen
Prevention is not passive. It is the active, daily practice of protecting the collagen you have and supporting the skin’s ability to maintain itself. Each of the causes outlined above has a corresponding preventive strategy - and together, they form the foundation of any effective under-eye wrinkle routine.
SPF Every Single Day - Without Exception
Daily SPF is the single most effective anti-ageing intervention available over the counter. Full stop. If you are doing nothing else for your under-eye area, wearing sunscreen every morning is the change that will make the most difference over time.
Applying SPF to the periorbital area specifically requires a little care - some formulas sting near the eyes, and many people avoid the zone entirely as a result. The Dewy Sunscreen SPF 30 is a lightweight, comfortable option that works well close to the eye area without irritation. At £15, it is one of the most cost-effective anti-ageing purchases you can make. Apply it as the final step of your morning routine, every morning, regardless of whether you plan to be outdoors. UVA rays are present year-round, penetrate cloud cover, and pass through window glass. There is no day off from UV exposure, which means there is no day off from SPF.
For more detail on how SPF works and why broad-spectrum protection matters, see our guide to what SPF is and how it protects your skin.
Vitamin C as Antioxidant Defence
SPF blocks UV rays from reaching the skin, but it does not neutralise the free radicals that are generated when UV and environmental pollution interact with skin cells. That is where Vitamin C comes in. As a potent antioxidant, Vitamin C scavenges free radicals before they can damage collagen, and it also supports collagen synthesis directly - making it an ideal complement to SPF in a morning routine.
The 15% Vitamin C + EGF Serum at £15 delivers a clinically meaningful concentration of Vitamin C alongside Epidermal Growth Factor, supporting both antioxidant defence and skin renewal. Applied in the morning before SPF, it creates a protective environment that actively works against the photoageing process that drives under-eye wrinkle formation. For a deeper look at how this ingredient works, visit the Vitamin C ingredient guide.
Consistent Hydration - Applied Correctly
Keeping the periorbital skin consistently hydrated is a prevention strategy as much as a treatment one. Well-hydrated skin maintains better barrier integrity, recovers more effectively from daily stressors, and is less likely to develop surface-level dehydration lines that compound the appearance of structural wrinkles.
The technique of application matters here, particularly around the eyes. Always apply products to this area using your ring finger - it is the weakest finger on your hand, which makes it the least likely to apply excessive pressure. Use a gentle tapping motion, working from the inner corner of the eye outward along the orbital bone. Never drag, rub, or pull the skin in this area. The mechanical stress from repeated rough handling accelerates the very changes you are trying to prevent.
Lifestyle Factors That Support the Under-Eye Area
“Sleep is the closest thing we have to a fountain of youth.” - Dr. Murad, dermatologist and founder of Murad Skincare
Quality sleep matters for skin repair. During sleep, the body increases collagen production and cell turnover - processes that are suppressed when sleep is consistently poor. Sleeping on your back, or on a silk pillowcase, reduces the mechanical compression on the face that can deepen expression lines over time. Sleeping with your head slightly elevated also assists with fluid drainage, which can reduce morning puffiness in the under-eye area.
UV-protective sunglasses serve double duty: they protect the delicate periorbital skin from direct UV exposure, and they reduce the habitual squinting that contributes to repeated muscle contraction. Diet and hydration play their roles too - a diet rich in antioxidants and adequate daily water intake support skin health from within, though no supplement replaces the topical and protective steps described here.
Start Retinol Proactively
One of the most effective things you can do for under-eye wrinkles is introduce a retinoid before deep wrinkles have formed. Retinol works by stimulating collagen production and accelerating skin cell turnover - and this process takes time. Starting early means you are building on a stronger structural foundation, rather than playing catch-up once changes are already established. Even a low-strength retinoid used consistently from your mid-twenties can make a meaningful long-term difference. We will cover the specifics of which retinoid and how to use it in the next section.
Prevention sets the ceiling on how much structural damage accumulates over time. Treatment is what addresses what is already there - and the right ingredients make both possible simultaneously.
The Best Ingredients for Treating Under-Eye Wrinkles
This is the section that separates effective under-eye wrinkle treatment from guesswork. The skincare market is full of products that promise to address fine lines and wrinkles - but the claims are only as credible as the ingredients behind them. Here is what the evidence supports, what each ingredient actually does for the periorbital area specifically, and which formulations deliver it effectively.
Retinol and Retinal - The Gold Standard for Collagen Stimulation
Retinoids - the family of ingredients derived from Vitamin A - are the most clinically supported topical actives for fine lines and wrinkles. The mechanism is well established: retinol converts in the skin to retinoic acid, which binds to retinoid receptors in the dermis and stimulates fibroblasts to produce new collagen. It also accelerates skin cell turnover, improving surface texture and reducing the depth of established wrinkles over time.
Retinal (retinaldehyde) is one step closer to retinoic acid in the conversion process, which makes it more potent than retinol at equivalent concentrations while still being well tolerated when formulated correctly.
For beginners: The Starter Retinol is the ideal starting point. It is formulated at a low concentration designed to deliver genuine results while minimising the irritation - dryness, flaking, sensitivity - that can occur when retinoids are introduced too quickly, particularly around the delicate periorbital area. If you have never used a retinoid before, or if you have previously experienced irritation with stronger formulations, this is where to start. Introduce it gradually: 2-3 nights per week initially, building toward nightly use as your skin adapts.
For those with retinoid experience: The Advanced Retinal is the logical next step for those who have established a retinoid routine and are ready for stronger, faster results. Retinaldehyde’s proximity to retinoic acid in the conversion pathway means it works with greater efficiency - delivering more pronounced improvements in wrinkle depth and skin texture compared to standard retinol at a similar tolerance level. For those whose skin has adapted to regular retinoid use, this is the upgrade that accelerates progress.
Both products are PM-only steps. Retinoids make the skin more photosensitive, which makes daytime use counterproductive - you would be accelerating the very UV damage you are trying to undo. To understand the science behind how this ingredient family works in greater depth, the retinol ingredient guide is a thorough resource.
Hyaluronic Acid - Hydration That Visibly Plumps
Hyaluronic acid is a humectant - a molecule that draws water from the environment and from deeper skin layers and holds it at the surface. It is capable of holding up to 1,000 times its own weight in water, which is what makes it so effective at restoring plumpness and smoothing the appearance of surface-level dehydration lines.
For the under-eye area specifically, hyaluronic acid addresses the dehydration component of fine line formation - the part that can be improved quickly and noticeably. Applied to damp skin, it locks in that surface moisture and keeps periorbital skin looking fuller and more hydrated throughout the day.
The Hyaluronic Acid Serum at £9 is formulated with 2% hyaluronic acid at three molecular weights - each penetrating to a different depth in the skin - plus Matrixyl 3000, a peptide complex that signals collagen production. It is one of the most cost-effective steps you can add to an under-eye wrinkle routine, and it works in both AM and PM. For a thorough breakdown of how this ingredient works, see the hyaluronic acid guide.
Peptides and Ceramides - Structural Support and Barrier Reinforcement
Peptides are short chains of amino acids that act as signalling molecules in the skin. When applied topically, certain peptides communicate to fibroblasts that collagen synthesis is needed - essentially sending a message that prompts the skin to produce more of its own structural protein. Ceramides, meanwhile, are lipids that form a critical part of the skin’s moisture barrier. When the barrier is intact, skin retains water more effectively and is better protected against environmental stressors.
The Bio-Active Ceramide Moisturiser at £19 is clinically proven to firm, plump, and reduce six signs of ageing in 28 days. Bioactive Ceramide NP strengthens the skin barrier, while Gransil Blur XL provides an immediate soft-focus effect on fine lines - a visible improvement from day one while the longer-term collagen benefits accumulate over weeks of use. This is the moisturising step in both the AM and PM routines described below.
Caffeine - The Eye Area’s Morning Essential
Caffeine is a vasoconstrictor - it temporarily narrows blood vessels, which reduces the fluid retention and puffiness that accumulates overnight beneath the eyes. It is not a wrinkle treatment in the strict structural sense, but it plays an important role in the morning routine: reducing the puffiness and darkness that make fine lines look more pronounced, and delivering peptide-based fine line support simultaneously.
The Caffeine Eye Cream at £10 contains Matrixyl 3000 alongside caffeine, making it a genuinely dual-action AM eye step - addressing puffiness and darkness in the short term while providing peptide support for fine lines over time. Applied with the ring finger using a gentle tapping motion from the inner corner of the eye outward, it is the dedicated eye treatment in a morning routine targeting under-eye wrinkles.
With the key ingredients understood, the question becomes how to bring them together into a practical daily routine - morning and evening - that works in real life.
Building a Daily Under-Eye Wrinkle Routine
Knowing which ingredients to use is only half the equation. The other half is knowing how to layer them, in what order, at what time of day, and with what expectations. A well-constructed routine is not complicated - it is consistent, logical, and built around a handful of well-chosen products.
For a broader look at how to structure your overall skincare approach, the complete skincare routine guide is a useful reference.
Morning Routine
Your morning routine focuses on hydration, protection, and antioxidant defence. Retinoids are not part of your AM routine - UV exposure makes retinoid-treated skin more photosensitive, so using them in the morning would undermine both their efficacy and your skin’s UV resilience.
- Cleanse gently - Remove any overnight product residue without stripping the skin.
- Apply Hyaluronic Acid Serum to damp skin - The dampness is important. Hyaluronic acid draws in whatever water is available, so applying to damp skin maximises absorption and gives it more to work with.
- Apply Caffeine Eye Cream around the orbital bone - Use your ring finger only. Tap gently from the inner corner of the eye outward. Do not rub or drag the skin.
- Apply Bio-Active Ceramide Moisturiser - Seals in hydration from the hyaluronic acid step and supports barrier integrity throughout the day.
- Apply Dewy Sunscreen SPF 30 - The final and non-negotiable step. Apply to the full face including the periorbital area, every morning.
Evening Routine
Your evening routine focuses on repair, renewal, and barrier support. This is when your retinoid does its most important work - overnight, when skin cell turnover naturally accelerates and the absence of UV exposure means no photosensitivity risk.
- Cleanse thoroughly - Remove SPF, makeup, and the day’s environmental buildup completely. A clean surface maximises active ingredient absorption.
- Apply Hyaluronic Acid Serum to damp skin - Same technique as the morning: apply to slightly damp skin for best absorption.
- Apply Starter Retinol (beginners) or Advanced Retinal (experienced users) - Apply across the face including the under-eye area. Start with 2-3 nights per week and build toward nightly use as your skin adjusts. PM only.
- Apply Bio-Active Ceramide Moisturiser - Seals in hydration and provides barrier support overnight, helping to offset any dryness associated with retinoid introduction.
Application Technique for the Eye Area
Technique is not a minor detail when it comes to the periorbital zone - it is part of the treatment. Always use your ring finger when applying any product around the eyes. It is the weakest finger on your hand, which naturally limits the pressure applied. Use a light tapping or patting motion, working from the inner corner of the eye outward along the orbital bone. Never drag, pull, or rub. Repeated mechanical stress on this thin skin contributes to the very structural changes you are working to address.
When to Expect Results
Being honest about timelines is part of setting up a sustainable routine. Here is what consistent use of this regimen delivers, and when:
- Surface hydration improvement: Visible within days of starting hyaluronic acid and the Caffeine Eye Cream.
- Visible fine line improvement from retinoids: Expect 6-8 weeks of consistent nightly use before the collagen-stimulating effects become apparent at the surface.
- Structural wrinkle improvement: Meaningful, measurable change in deeper wrinkle depth requires 3-6 months of consistent nightly use. The ingredient works - but it works on the skin’s own timeline, not overnight.
Consistency is the most important variable in any skincare routine. A strong routine applied sporadically will always underperform a simple routine applied every day.
Under-Eye Wrinkles vs. Dark Circles: Two Different Concerns
Under-eye wrinkles and dark circles are frequently discussed together - and frequently confused. Both affect the periorbital area, both become more noticeable with age and fatigue, and both are concerns for many of the same people. But they are not the same concern, and they are not addressed by the same ingredients.
Under-eye wrinkles are a texture and structure concern. They are caused by collagen loss, skin thinning, repeated muscle movement, and UV damage. Treating them requires ingredients that rebuild or protect collagen - primarily retinoids - and ingredients that restore hydration to reduce the appearance of surface-level dehydration lines.
Dark circles are a colour and tone concern. They can be vascular in origin (visible blood vessels beneath the thin periorbital skin), pigmentary (post-inflammatory hyperpigmentation or melanin deposition), or structural (the shadowing effect created by hollowing beneath the eye). Each type has its own treatment strategy.
Both can be present simultaneously - and often are. But using only a hydrating eye cream to treat structural wrinkles will not produce meaningful structural improvement. Retinoids are needed for that. Conversely, applying a retinoid alone will not address the vascular or pigmentary causes of dark circles - targeted ingredients are required. Understanding which concern you are primarily dealing with allows you to direct your routine appropriately.
The Caffeine Eye Cream addresses both sides of this picture to a degree - peptides for fine line support, caffeine for puffiness and vascular dark circles. For a full breakdown of how to address the dark circle concern specifically, the dark circles and under-eye puffiness guide covers the topic in detail.
Frequently Asked Questions About Under-Eye Wrinkles
How do I get rid of under-eye wrinkles?
The most effective topical approach combines a retinoid used in the evening to stimulate collagen production, hyaluronic acid to restore hydration and surface plumpness, and daily SPF to prevent further UV-driven damage from compounding existing lines. For beginners, the Starter Retinol is the ideal entry point into retinoid use around the eye area. For those who have already established a retinoid routine and want stronger results, the Advanced Retinal delivers a more potent and efficient conversion to retinoic acid. In the morning, the Caffeine Eye Cream provides Matrixyl 3000 peptide support for fine lines alongside immediate puffiness reduction. Results are driven by consistency over weeks and months - not single applications.
What causes fine lines under the eyes?
Fine lines under the eyes are caused by a combination of collagen and elastin loss (which naturally accelerates from the mid-to-late twenties), repeated contraction of the orbicularis oculi muscle during blinking, squinting, and expression, cumulative UV exposure that degrades collagen fibres through photoageing, and skin dehydration that reduces surface plumpness and makes shallow lines more visible. The periorbital skin is the thinnest on the face - approximately 0.5mm compared to roughly 2mm elsewhere - making it significantly more vulnerable to all of these factors than the rest of the face.
Can dehydration cause under-eye wrinkles?
Dehydration does not cause structural wrinkles, but it significantly worsens their appearance and can create surface-level lines that closely resemble early wrinkles. These dehydration-related lines are reversible with consistent and correct use of hydrating ingredients - particularly hyaluronic acid applied to damp skin. For more on the difference between dehydrated and dry skin, and how to identify which applies to you, see the guide to dehydrated skin.
Is retinol safe to use around the eyes?
Yes - when the right formulation is used and introduced gradually. The skin around the eyes is sensitive to irritation, which is why beginning with a low-strength formulation is important. The Starter Retinol is specifically formulated as a gentle, well-tolerated entry point. Those who have already built up retinoid tolerance and want stronger results can progress to the Advanced Retinal. Both should be introduced at a frequency of 2-3 nights per week and used as a PM-only step. For a complete breakdown of how retinoids work, what to expect, and how to introduce them safely, the retinol ingredient guide covers everything you need to know.
How long does it take to see results from under-eye wrinkle treatments?
The timeline varies by ingredient and concern. Hydration-related improvement - surface smoothing and plumpness from hyaluronic acid - is often visible within days. Retinoid-driven collagen improvement requires significantly more time: expect 6-8 weeks of consistent nightly use before visible improvement in fine line depth, and 3-6 months of continued use for meaningful structural change in more established wrinkles. The most important variable in any under-eye wrinkle routine is consistency. Sporadic use produces limited results; daily and nightly application of the right ingredients over months produces real, measurable change.
Putting It All Together
Under-eye wrinkles are driven by a convergence of factors - collagen loss, cumulative UV exposure, the daily mechanics of facial expression, and dehydration. None of these causes is mysterious, and none requires an elaborate or expensive response. What they require is the right ingredients, applied correctly and consistently, over enough time for the skin to respond.
The prevention strategy is straightforward: protect existing collagen with daily SPF and Vitamin C antioxidant defence, maintain periorbital hydration with hyaluronic acid, and introduce a retinoid proactively before deeper structural changes have the opportunity to set in. The treatment strategy is equally clear: retinoids stimulate new collagen production over time, hyaluronic acid restores hydration and plumpness, peptides and ceramides provide structural and barrier support, and caffeine addresses the puffiness that makes lines look more pronounced.
Applying these ingredients in the right order - hydration, eye treatment, moisturiser, SPF in the morning; hydration, retinoid, moisturiser at night - creates a routine that works on multiple mechanisms simultaneously. Technique matters too: ring finger only, gentle tapping from inner corner outward, and never dragging the skin.
The timeline is honest. Surface improvement from hydration comes quickly. Structural improvement from retinoids takes weeks to months. But the change is real, measurable, and worth the consistency it requires. The under-eye area is one of the most responsive zones on the face when the right approach is applied - thin skin means actives reach their targets efficiently, even if that same thinness is what made the area vulnerable to begin with.
