If the thought of having acid on your face concerns you – which makes sense – then glycolic acid peels are among the least threatening of the bunch. That’s because glycolic acid comes from a family of fruit acids. In other words, it’s all natural. Still, a glycolic acid concentration of more than 10 percent is considered a hazardous material, and the typical concentration for peels is about 50 percent.
Glycolic acid is applied to the skin using a sponge. The acid is rinsed from the face once the desired number of layers is removed. The skin will be pink, and it’ll peel in subsequent days. Approximately a week later the process will be complete.
