I only left the TCA 30 on my skin for about 2 minutes. My skin was not as red as I thought, but then again, I only left it on for 2 minutes instead of the recommended 4-5. My skin did peel a lot, after it got crinkly, and the entire skin peeled. I'm afraid that I would look not representable to the public for way too long if I leave it on longer. I did moisturize like crazy. The peeling itself is not that bad, but it's the very brownish looking skin, that will then turn VERY red.
