Does a 12% TCA Peel Need to Frost in Order to Work?

I bought a tca peel on line and did a patch test on my leg. It did not frost after a couple of coats. I washed it off and nothing happened to my skin. I want to try it on my face but I'm wondering if 12% tca peels frost on your face? How do you know when you have applied enough solution?

TCA peel needs higher concentration to work

A 12% TCA peel does very little that is beneficial to the surface of the skin. A frostwill occur with a much stronger concentration, usually at least 35%. Furthermore,I am not a fan of TCA peels.

In my opinion, the best superficial skin resurfacing is with the use of unbuffered low pH glycolic acid. We perform glycolic peels with 50%... more

DIY facial peels with TCA are risky!

TCA, or trichloroacetic acid, is a chemical commonly used by medical professionals for facial rejuvenation. Essentially, it is a caustic acid that burns off the superficial layer of the skin, so there are definite risks involved. The results depend both upon application technique and the concentration of the acid in the solution. Although 12% is on the low side, I really don't see this as a do-it-yourself procedure.
