Retinol is quite the cult ingredient and for good reason. It powerfully resurfaces your skin to minimise the appearance of wrinkles, lines, and scars. Retinol is a star ingredient for brightening skin to counteract dark spots, blotches, and sun damage. Be aware that this acid requires patience – it can take a couple of months to see the effects.
Retinol is derived from vitamin A. It absorbs deep into your skin where it becomes retinoic acid. Our skin has receptors for this acid, which it binds to. Once this happens, retinol encourages faster cell regeneration and increased collagen production.
Most skin types can use retinol. People concerned with acne or aging skin can see real improvement with time. It's not recommended if you have very sensitive skin as it can cause irritation.
