If you had expanded this choice, to include the other Retinoids: Tazarotene and Tretinoin, I would have chosen either of them, without question.
This is because they are Retinoids. Differin is not exactly a Retinoid. It is a designed drug which turns on the Retinoid receptor. It PROBABLY has strong anti-aging effects. However, this has not been determined convincingly yet: the FDA has approved the other two drugs as effective for anti-aging, but not Differin as yet.
Avene's Diroseal product, has a Retinyl aldehyde ingredient. While Diroseal is an excellent product, with a marvelous base, its Retinyl aldehyde is dead last (kinda like my horse in the Kentucky Derby today), in its list of ingredients. Thus, its anti-aging effect may be quite low. Also, Aldehydes must be converted in the skin to an acid form to have as much anti-aging effect.
Diroseal is a great product for soothing the skin, taking redness out, and the Retinyl aldehyde will cause some favorable thickening of the skin. However, if choosing between the two for an anti-aging effect, I would cast my lot with Differin.
