AHA, BHA, TCA, and More: Understanding Chemical Peel Formulations
Not all chemical peels are the same. The acid used, its concentration, the pH of the solution, and how long it stays on the skin all determine the depth and effect of the treatment. Choosing the right peel formulation is essential for safety and results — and the growing variety of options is a key feature of the chemical peel market.
The chemical peel market includes a wide range of peeling agents: alpha-hydroxy acids (AHAs), beta-hydroxy acids (BHAs), trichloroacetic acid (TCA), and combinations. Each formulation targets specific skin concerns and depth levels, and manufacturers are increasingly offering customized and combination peels.
Common Peeling Agents
-
Glycolic acid (AHA): superficial peels, improves texture and tone
-
Lactic acid (AHA): gentle exfoliation, suitable for sensitive skin
-
Salicylic acid (BHA): oil-soluble, ideal for acne-prone skin
-
Mandelic acid: gentle, larger molecule, good for sensitive or darker skin tones
-
TCA: medium to deep peels, stronger resurfacing
-
Jessner's solution: combination peel for medium depth
Matching Peel to Concern
Acne-prone skin often benefits from salicylic acid peels. Pigmentation and dullness may respond to glycolic or lactic acid. Fine lines and more significant sun damage may require TCA. Skin type, tone, and sensitivity all influence selection.
People Also Ask
Which chemical peel is best for acne?
Salicylic acid (BHA) peels are often recommended for acne-prone skin because they penetrate pores and reduce oil. Other peels may be combined depending on skin needs.
Is TCA stronger than glycolic acid?
Yes. TCA peels typically penetrate deeper than glycolic acid peels and are used for medium to deep resurfacing, while glycolic acid is commonly used for superficial peels.
Safety and Skin Tone Considerations
Darker skin tones require careful peel selection to reduce the risk of post-inflammatory hyperpigmentation. Gentle peels and careful priming with topical agents can improve safety. Professional assessment is essential before treatment.
