What determines the effectiveness of a chemical peel?

The effectiveness of a chemical peel is primarily determined by the pH and concentration of the acid applied to the skin. The pH level of a chemical peel solution is critical because it influences the depth of exfoliation, the rate of skin penetration, and the overall efficacy of the treatment. A lower pH typically means a stronger peel, which can penetrate deeper into the skin, leading to more significant results.

Additionally, the percentage of the acid is also crucial; higher concentrations generally yield more substantial exfoliation and skin rejuvenation. Different types of acids (e.g., glycolic, salicylic, trichloroacetic acid) react differently based on their formulation and concentration, which affects their effectiveness for various skin types and conditions.

Together, the pH and percentage of the acid dictate how well the peel can treat specific skin issues, making it a fundamental aspect of chemical peel effectiveness.
