What is Chemical Peeling?
Chemical peeling is a treatment technique used to improve and smooth the texture of the facial skin using a chemical solution that causes the skin to blister and eventually peel off. The regenerated skin is smoother and less wrinkled than the old skin. Some types of chemical peelings can be purchased and administered without a medical license, however people are advised to seek professional help from a plastic surgeon or dermatologist on specific types of chemical peelings before a procedure is performed.
Types of Chemical Peelings:
1) Alpha hydroxy acid peelings
Alpha hydroxy acids (AHAs) are naturally occurring organic carboxylic acids such as glycolic acid, a natural constituent of sugar cane juice and lactic acid, found in sour milk and tomato juice. This is the mildest of the peel formulas and produces light peels for treatment of fine wrinkles, areas of dryness, uneven pigmentation and acne. Alpha hydroxy acids can also be mixed with a facial wash or cream in lesser concentrations as part of a daily skin-care regimen to improve the skin’s texture.
AHA peels are used to:
- Reduce fine lines and wrinkling
- Reduce uneven pigmentation
- Aid in the control of acne
- Treat areas of dryness
- Smooth rough, dry skin
- Improve the texture of sun-damaged skin
2) Trichloroacetic acid peels
Trichloroacetic acid (TCA) is used as an intermediate to deep peeling agent in concentrations ranging from 20-50%. Depth of penetration is increased as concentration increases, with 50% TCA penetrating into the reticular dermis. Concentrations higher than 35% are not recommended because of the high risk of scarring.
Trichloroacetic acid peels are used to:
- Smooth out fine surface wrinkles
- Remove superficial blemishes
- Correct skin pigment problems
- Suitable to use on darker skinned patients over Phenol
