Skincare Addiction is a subreddit dedicated to finding, and sharing tips on how to use, evidence-based skin products. If you are unsatisfied with the condition of your skin, the sidebar links are a good place to start. (I personally found good results from using "double cleansing" [oil cleansing and then water-soluble face cleanser] and an AHA-based exfoliator. I also use a moisturizer afterwards, but that was something I did already. Your results will probaby vary.)
