I put on one layer of TCA peel once I had diluted a 25% to 12%. I put it on my elbows and knees but there's no peeling. It's been 5 days already.. I should've done more layer maybe.. but I was afraid I might burn myself if I didn't start off with a small peel. I need to get rid of my dark elbows and knees!! Summer has arrived.
Success with glutathione?
