Most simply put, retinol is another name for vitamin A and works by stimulating the natural renewal process in skin cells, which slows as we age. It improves wrinkles caused by photo-aging and evens out skin tone and texture. Look for products that contain at least 0.5 percent retinol, then work up to one percent for best results, and use them only at night – protect skin during the day with an SPF 30 or higher because retinol sensitizes the skin. Laboratoire Dr Renaud is currently working on formulating retinal molecules, which are easier for our cells to turn into retinoic acid. Retinal will not only perform better than retinol but also be better suited to those with sensitive skin.
