Cleopatra and the ancient Romans used various food acids to peel their skin. In the early 1900s, European and American women underwent ‘non-medical’ peels in salons with secret formula, which were probably mild acids. In the early 1950s, the phenol peel was developed. This was a fierce, deep peel that could remove years of wrinkles, but also gave peeling a bad reputation for complications - pigmentation, depigmentation, and scarring. Today, Trichloroacetic acid (TCA), being a more gentle acid, is used because it rejuvenates the skin without the risk of serious side effects. Jessner Peels are also now popular. They are not as deep as TCA peels, and therefore have less ‘down-time’.
