If you’re new to retinol, there are a few things to know. First, start off slow; don’t use the product every single night. If you want to acclimate your skin and lower the risk of the retinol uglies, use your retinol product once every other night or once every three nights and slowly increase the frequency from there. Also consider mixing retinol gels or serums into your moisturizer for a few weeks, which will force the product to be easier on your skin. Keep the amount of serum/gel small when you’re just starting out—use just a few drops of serum or a dollop of gel no larger than a pea.
