The importance of Cellular repair at night
Skin's circadian repair peaks at night, boosting fibroblast activity, lipid production, DNA repair, and collagen/elastin synthesis while barrier permeability aids active penetration. SkinCeuticals Resveratrol B E (1% resveratrol, 0.5% baicalin, 1% vitamin E) fortifies overnight antioxidant defences, neutralises free radicals, enhances radiance/firmness, and creates a resilient base for retinol—apply before retinol on dry skin, or alternate nights when building tolerance.
