During the 1990s, a fair bit of research was conducted on TCA, mostly because (via chlorine) it can end up in the water system. Reviews of various tests, came up with conclusion that it is “not considered to be carcinogenic to humans”.
A study on 65 people in Korea (using TCA at 65% or 100% concentrations) showed it to be an effective treatment for acne scars. What interested me about this research was the authors did not want to conduct deep peels because of complications such as damage to adjacent normal skin, but instead used high concentrations of TCA targeted directly on each scar “pressing hard” with a wooden applicator.
Lot of great reviews on people also using TCA for sun damages or scarring on legs, arms and body parts.
Medium depth peels are usually performed with trichloroacetic acid (TCA) in concentrations ranging from 20-35%. Although there are formulations of 50%, they generally not recommended because of the high risk of scarring associated with this depth of penetration. Apparently 11-20% concentrations of TCA will penetrate one–to-two layers of the epidermis.
The concentration of I'M FABULOUS Gorgeous Peel is less then 11%. You will not get down time. It is safe and easy to use.
