Starter Retinol Serum - 30ml | £12

★★★★★ 4.8 Stars | 92 Reviews

If you've been curious about retinol but nervous about irritation, this is your starting point. The Starter Retinol Serum is clinically proven to smooth fine lines in just 7 days* - with 95% of users experiencing zero irritation.** It's not a watered-down beginner option. It's a genuinely high-performance formula, engineered to be gentle enough for first-time users and sensitive skin.

The secret is in the delivery system. Rather than exposing your skin to a direct hit of retinol, the formula uses 1% Granactive Pro+ - an encapsulated dual-retinoid complex that combines slow-release Granactive Retinoid with a trace of Retinal. In independent testing, this approach proved 2x more effective than standard retinol* while remaining gentle enough for those who have struggled with retinol in the past.

Why it works:

- Encapsulated delivery releases retinoid gradually, reducing the risk of irritation

- Dual-retinoid complex (Granactive Retinoid + Retinal) means you get both gentle and effective in one step

- 0.5% Amisol Trio supports your skin barrier throughout the adjustment period

- 0.2% SymRelief actively calms any sensitivity from day one

Best for: Retinol beginners | Sensitive & easily irritated skin | First-time retinoid users | Anyone who's had a bad experience with retinol before

Skin types: All skin types

Targets: Fine lines & wrinkles | Uneven skin tone | Rough texture

Not suitable for pregnancy or breastfeeding

90% saw significant improvement in wrinkles in 4 weeks***

What our customers say:

"Great starter retinol serum, I've used since end of November twice per week. It works for my dry, sensitive skin. Did not irritate my face. Will continue to use it. So far my forehead looks more smooth than before." - Mel, verified buyer

Advanced 0.2% Retinal Serum - 15ml | £15

★★★★★ 4.6 Stars | 124 Reviews

Already using retinol and ready to see faster, more visible results? This is the upgrade. The Advanced 0.2% Retinal Serum is clinically proven to work up to 11x faster than standard retinol** - and visibly reduces deep wrinkles in as little as 1 week* in clinical testing.

The difference comes down to the ingredient itself. While standard retinol needs two conversion steps before it becomes active retinoic acid in the skin, retinal (retinaldehyde) needs only one. That single step is why retinal delivers faster, more visible results for those whose skin has built tolerance to retinol. At INKEY, our retinal is encapsulated - so even at 0.2%, it's controlled and well tolerated.

The formula goes further than just retinal. 2% Sirtalice - a marine ferment - delivers visible firming within 30 minutes. In clinical testing, 85% of users saw firmer, more lifted-looking skin in 4 weeks.**

Why it works:

- 0.2% Encapsulated Retinal - one step from retinoic acid, protected in a stabilising shell for controlled release

- 2% Sirtalice - marine firming complex, clinically proven visible lifting from 30 minutes

- SymSitive 1609 - calming complex to support barrier comfort during step-up use

- Targets all five signs of skin ageing in a single formula

Best for: Experienced retinoid users | Those targeting multiple signs of ageing | Skin that has fully adjusted to retinol and is ready to step up

Skin types: All skin types

Targets: Deep wrinkles | Firmness & lift | Dark spots | Skin radiance | Uneven texture

Not suitable for pregnancy or breastfeeding

Clinical results:

Clinically proven to visibly reduce deep wrinkles in 1 week*

Works up to 11x faster than standard retinol****

85% saw firmer, more lifted-looking skin in 4 weeks**

80% saw visible improvement in skin radiance**

💡 INKEY Tip: Pair with the Exosome Hydro-Glow Complex before application. In clinical testing, the combination was proven to reduce the appearance of fine lines by 82% in just 8 days.***

What our customers say:

"After 2 weeks, I am starting to see visible results. My dark spots are starting to disappear and my fine lines are a little smoother. It definitely works! Can't wait to keep using and seeing more results for the upcoming weeks." - Vuri, verified buyer

Retinol Eye Cream - 15ml | £13

★★★★☆ 4.2 Stars | 360 Reviews

The skin around your eyes is thinner and more delicate than anywhere else on your face - which means your regular retinol serum isn't the right tool for this area. Standard serums are formulated for facial skin. Our Retinol Eye Cream is built specifically for the eye contour: a slow-release retinoid formula that targets fine lines and crow's feet without the risk of irritation that a full-strength serum could cause.

The active ingredient is 3% Vitalease - a stabilised, slow-release retinoid compound designed to deliver retinol's benefits to the delicate eye contour at a controlled rate. It's supported by Glycerin and Shea Butter for comfort and hydration, making it an overnight treatment that works while you sleep.

Why it works:

- 3% Vitalease - slow-release retinoid compound specifically developed for the sensitive eye area

- Glycerin - draws moisture into the skin and keeps the delicate contour hydrated

- Shea Butter - soothes and conditions the eye area through the night

- Lightweight enough to not cause milia or congestion around the eyes

Best for: Fine lines & crow's feet | Anyone new to eye area retinol | Completing a full retinol routine

Skin types: All skin types

Targets: Fine lines & wrinkles around the eye area | Skin smoothness | Eye area renewal

Not suitable for pregnancy or breastfeeding

What our customers say:

"I've been using The INKEY List Retinol Eye Cream for about two months, and I'm genuinely impressed. My under-eye area looks smoother, more even, and less tired - without any irritation, redness, or dryness. The texture is lightweight, absorbs quickly." - Andrea S., verified buyer

💡 INKEY Tip: Our Retinol Eye Cream isn't just for under the eyes. It can also be used to target fine lines around the mouth - just avoid applying directly on the lips. And in the morning, pair it with the Caffeine Eye Cream to target puffiness and dark circles. Caffeine Eye Cream in the AM, Retinol Eye Cream in the PM - a complete two-step eye routine.

If you've never used a retinoid before, or if retinol has irritated you in the past - start with the Starter Retinol Serum. If you've been consistent with retinol for 3+ months and want faster, more advanced results - step up to the Advanced 0.2% Retinal Serum.
