Retinol (vitamin A), is a skincare superstar. When applied topically, retinols can improve the appearance of fine lines and wrinkles, reduce hyperpigmentation (such as age spots and sun damage) and stimulate collagen production in the skin. Skincare products with retinol accelerate the rate of skin cell turnover, which promotes the growth of new, healthy cells. It is important to keep in mind that integrating retinol into your routine requires a bit of strategy to maximize its benefits and minimize side effects.
