| Re: AHAs and retin a
I found these quotes form this site Paula B.'s Cosmetic Cop Site:
"If you are seeing a physician, he or she may recommend a prescription treatment like as Retin-A, Differin, or Azelex (contains azelaic acid, which is not a retinoid but more like an AHA with some antimicrobial activity that is prescription only). If you use both a retinoid and an AHA or BHA, you can use the AHA or BHA during the day and the Retin-A, Differin, or Azelex at night. Some dermatologists recommend applying the AHA or BHA first and then applying Retin-A, Differin, or Azelex directly over top. The thought is that the AHA or BHA boosts the effectiveness by increasing penetration of the other products. Again, experiment to see what works best for your skin."
