This serum is the most effective way to improve skin health. Regardless of your age or skin type, retinol is a superstar skin-saver. It gives the skin a healthy glow. Retinol has a dual effect: Not only does it decrease the amount of collagen breakdown from sun exposure by preventing the increase of an enzyme called collagenase, but it also helps to stimulate the production of new collagen. Reduce blackheads and whiteheads and minimize pores. Retinol promotes the production of new skin cells, effectively pushing oils and dead skin out of blocked pores. By doing so, it also prevents new blackheads and whiteheads from forming. No Dyes, No Fragrances Size: 30ml / 1oz fl. Malathii Retinol Serum Evening 30ml
