Red light therapy has become a popular non-invasive treatment for skin concerns like fine lines, redness, acne, and dullness. Using specific wavelengths of red and near-infrared light, it helps stimulate cellular energy, supporting collagen production, healing, and overall skin renewal.

In this guide, we explore how red light therapy works, the benefits backed by research, and key safety considerations. We’ll also highlight effective skincare alternatives that can deliver similar results, including clinically proven ingredients like retinoids, vitamin C, peptides, niacinamide, and ceramides — with targeted INKEY List products to help you achieve healthy, glowing skin without investing in a device.

Retinol is one of the most effective ingredients for improving visible signs of ageing, but for rosacea-prone skin it’s often approached with caution. Increased sensitivity, persistent redness, and a weakened skin barrier can make traditional retinol formulas feel overwhelming.

The good news? Advances in formulation mean retinol is no longer a one-size-fits-all ingredient. With the right concentration, supportive ingredients, and a gradual introduction, rosacea-prone skin can benefit from retinol without compromising comfort. This guide breaks down what to know, what to avoid, and how to introduce retinol in a way that respects reactive skin.

Smart skinimalism is the 2026 skincare trend redefining results through simplicity.

So many things can cause facial redness—genetics, skin type, the environment, stress, breakouts, etc. With the right skin care formulas, you can not only soothe dry, itchy skin but you can prevent redness from happening in the first place. 

Niacinamide (vitamin B3) is one of skincare’s most researched ingredients—and for good reason. It works on multiple pathways at once: balancing sebum, supporting the skin barrier, soothing inflammation and helping improve the look of dark spots and fine lines. In this guide, we break down what niacinamide is, what it actually does, and how to layer it in your routine for clearer, more balanced skin.

If you’ve been exfoliating more than usual or using several actives in one go (think acids, retinols etc), you may experience certain symptoms that will point to over-exfoliation.  The most obvious symptoms include redness and irritation at the skin’s surface, which may also manifest through burning and inflammation. Learn how to prevent over-exfoliation and how to take care of skin that has been over-exfoliated

Stressed out skin can manifest in many ways, unfortunately. As stress can impact the skin’s natural protective barrier, there can be signs of dryness and dehydration, as well as inflammation and itchiness. You might also notice everything from pigmentation to dullness, and of course, there is the chance breakouts may appear. Learn what you can do to target stressed skin and what INKEY product are best suited to calming stressed skin.

Whether it’s an ongoing condition or sudden reaction, the skin can appear red for a number of different reasons with a spectrum of severity - from health conditions such as Rosacea and dermatitis, allergies, reactions to a flush from exercise, temperature etc. The accompanying factors to the redness, such as itchiness, inflammation or dryness, can help determine the cause and resolution of the concern. Learn more about why skin can appear red, what INKEY List product are best suited to target skin redness and tips to reduce the appearance of redness.

When discussing the skin barrier, we are referring to the outermost layer of the skin known as the epidermis. We can think of the epidermis a bit like a suit of armour and the first point of protection. The health of the skin barrier can directly correlate with how healthy your skin looks overall. When in good shape, your skin appears hydrated, plump and bright. If compromised, it can look dull, uneven, translucent and sagging with more visible lines and wrinkles. Learn more about what the skin barrier is, how it can be damaged and what INKEY list products help support and protect the skin barrier.
