Many different chemical peel agents are available on the market to effect a ‘hurt’ to the skin that results in a rejuvenation of the skin as it heals itself a few days after by increased collagen formation.
Medical grade trichlore-acetic acid (TCA) is 15% to 30% and should only be administered by a trained, experienced doctor. In the face, skin peels/sheds 3 – 5 days after the treatment and on the neck and chest area after 5 – 7 days. Hands take even longer, 7 – 10 days after treatment. Using specially formulated creams during the healing period can enhance the effect of the chemical peel.
Skin is more sun sensitive after peel treatments and sun protection with a high SPF should be worn during the course of peels. Usually 4 treatments of 15% TCA one week apart is recommended. Above 22% TCA treatment should not be closer than 6 weeks apart.
