It creates a smoother skin tone with reduced pigmentation and pores, while smoothing fine lines. Vitamin A also acts as a powerful antioxidant that revives the production of collagen and elastin. A booster with 0.3% pure retinol Grade Up Retinol 0.3%+ is our most potent booster that contains the maximum permitted dose of vitamin A. Therefore, it should not be mixed with other boosters or acids. Retinol helps to ‘train tired skin cells’ and provides a rebuilding and rejuvenating effect, smoothing fine lines and pigmentation. Retinol is effective because as it is absorbed by the skin, it is broken down and converted to vitamin A acid (also called retinoic acid). Retinoic acid is a compound that can directly affect skin cells and their behaviour. SUITABL
