70% TCA. Problem? (Photo)

By definition, the use of TCA in concentrations of 50% or more, or in concentrations of 25-35% in combination with other acids in higher concentrations, such as glycolic acid, actually constitute a medium depth peel or even deeper peel. And the deeper the peel, the more the potential for serious and potential irreversible complications. Furthermore, the use of higher concentrations on non-facial areas, such as the neck, chest and extremities, carries that much more of a risk for the development of prolonged post-treatment hyperpigmenation and even permanent loss of pigmentation and scarring. The more coats applied the stronger the peel and the greater the potential for problems. Prolonged redness is usually a sign of potential complications. Chemical peeling is an aesthetic specialty unto itself and takes training and experience to perform properly and safely. I certainly understand the allure of do-it-yourself home treatment to save time and money, but playing with strong acids on one's own is literally playing with fire. Let this serve as a warning to anyone else reading this column contemplating self-treatment with strong peeling agents. At this point, I would suggest seeing an aesthetic physician asap to evaluate your situation and initiate appropriate treatment. Best of luck to you.
