FWIW, Differin and Epiduo are both primarily prescribed as anti-acne treatments; my 14 yo has been using them daily for two years. They dry the skin more than they moisturize it (which is obvious when you consider that the primary component is strong peroxide.)
Both of them have recently been targeted by insurance companies for their cost, and are very quickly being eliminated from a lot of formularies. If you pay cash for them you can expect to pay somewhere between $100-150 for a 45 gm. tube (about 1.5 oz.)
I personally cannot touch retin-A; it burns like fire and makes my face so red I look like I'm about to have a coronary. No thanks; I look better with the wrinkles!
IME, the best strategy if you want to reduce the appearance of the wrinkles (you really can't eliminate them with topical treatments, just camouflage them) is to plump up the tissue under the skin, and tighten the skin itself. The best option for the first is drinking lots of water, and for the second, original Preparation H, which these days means the Canadian version, which still has live yeast derivative peptides in it. (Not something that you want to do daily, however, the steroid antinflammatories in it can thin the skin over time.)
If you are a makeup wearer, applying a makeup base that contains dimethicone will help to fill the wrinkles in temporarily, so that the makeup will not settle in them. Best deal for that is the Monistat Chafing Relief Powder Gel.
