I recently posted on the benefits of retinols and retinoids – yes, they’re wonderful and their benefits are backed by research. Several readers have since asked, “which retinol should I buy?” For prescription retinoids (the stronger version of vitamin A), the choice will involve a conversation between you and your dermatologist – when choosing a retinoid for my patient I keep in mind their skin type and any other skin conditions they may have. Retinols are available over the counter. They range quite a bit in price, but higher price does not necessarily mean a better product, and this is particularly true for retinols. Here are a few that I have tested, like and use: ROC Retinol Correxion for sensitive skin. This product is a milder retinol. It is a good starting product for anyone with sensitive or dry skin, as well as for someone who has not used a retinol previously.
