Retin-A can cause scaling, redness and sensitivity in the first month of use, and moisturizers can be very helpful in soothing this irritation. When looking for a moisturizer, make sure the bottle says "non-comedogenic" on the label; using a lightweight oil free moisturizer is a good option to prevent clogging of pores and acne. Ingredients that you want to avoid in your facial moisturizer are cocoa butter, lanolin, myristyl myristate and isopropyl myristate. Shea butter is not a bad ingredient in your moisturizer but you want to take a look at the other ingredients as well. The less refined the better. Look for lightweight moisturizers with hyaluronic acid and glycerin.
