But no one picked up on the retin-a part of the question. Retinoic acid (tretinoids) as I understand it do not cause exfoliation but repair photodamage at the deeper levels of the skin. The National Science Foundation says that this form of drug (also used in cancer treatments) inhibits telomerase and leads to telomere shortening. That sounds like it would speed skin aging. Since I use retin-a for acne and it works great fr me (I'm inmy 40s) I am now pretty concerned. Hi Left Brain,
