Retinol is a skincare ingredient derived from vitamin A. It is used to unclog pores, reduce fine lines, even out discoloration, and smooth the skin. Prescription formulas use stronger Retinoids, providing the most impressive results in as little as 4 weeks. But you don’t have to see the dermatologist to reap the benefits. Over the counter skincare products can contain retinol with a lesser potency. These results are seen in 2-3 months. When choosing an over the counter product a moisturizer, gel, serum, or lotion will give your skin optimal benefit.
