Retinol works by speeding up cell turnover rates, rapidly exfoliating the skin and decreasing the buildup of dead cells within the follicle. This, in turn, reduces the formation of comedones.
Not only does it help clear and prevent acne. For people who have post-inflammatory hyperpigmentation may find that retinol reduces the look of dark spots and discoloration left by acne breakouts and also acne scars. Retinol also stimulates collagen production, therefore reducing fine lines & wrinkles.
Retinol is a potent tool in treating acne and may cause some irritation and sun sensitivity. so it is important to apply it at night and increase usage slowly, follow instructions and always apply a high sunscreen daily.
