I've been using 25% TCA for a couple months on deep acne scars. While it's not really improving the ice picks, it is improving hyperpigmentation left behind from old breakouts. If I do a peel on Thursday night, it usually finishes peeling by Wednesday of the following week. Since I don't have time to take off work everytime I need to do a peel, I've been addressing small sections at a time. I wear SPF 70 during and after recovery.
I had a severe breakout about 6 months ago that left one whole side of my face completely scarred with hypermigmented spots. I have noticed a considerable improvement on the scars I've treated with TCA 25% vs the ones I have left to heal on their own.
To cover redness durning the healing process I use Bare Minerals makeup which is listed as safe to use after plastic surgery. I have no adverse reactions. Also, during the peeling process my breakouts have not increased. I do the peel during my menstral cycle, when breakouts have slowed.
