Retinol
The holy grail of anti-ageing, retinol is a potent form of vitamin A that enhances the skin's ability to repair and renew, while supporting collagen production. The result? Plumped out, smoother skin, and, with long term use, reduction in fine lines and wrinkles. Use a retinol product at night for best results, or during the day with an SPF moisturiser - vitamin A increases skin's sensitivity to the sun and increases the risk of sun damage.
