What is Retinol?

Retinol is a form of vitamin A found in many skincare products, including serums, moisturisers and eye creams. It’s best known for supporting skin renewal, which is why it’s often linked with brighter, smoother-looking skin over time.

Retinol also acts as an antioxidant, helping to neutralise free radicals – unstable molecules created by things like UV exposure and pollution – that can contribute to visible signs of premature ageing. Because it helps strengthen and refresh the skin’s surface, retinol can also support hydration and improve the look of uneven texture, breakouts and sun damage.

Retinol can be powerful, so it’s normal for skin to take a little time to adjust. If you’re new to it, start with a lower-strength retinol (such as 0.1% or below) and go slow: use it one to two nights a week, moisturise well, then build up gradually as your skin adapts (you can increase strength later if you need to).

Mild dryness, flakiness or redness can happen at first, but this usually settles. Stick to the directions and keep the rest of your routine simple and hydrating while you’re introducing it.

Because retinol can make skin more sun-sensitive, daily SPF is non-negotiable. It’s also best avoided if you’re pregnant, breastfeeding or trying to conceive and if you have very sensitive, eczema- or rosacea-prone skin, speak to a dermatologist or skincare professional to find the right strength and frequency.
