Which chemical is a primary component of deep peels?

Phenol is the primary component of deep peels due to its potent exfoliating properties and effectiveness in penetrating the skin. Deep peels are designed to treat more severe skin concerns, such as deep wrinkles, sun damage, and extensive pigmentation issues. Phenol works by disrupting the bonds that hold skin cells together, allowing for the shedding of the upper layers of skin and stimulating the production of new skin cells, which results in a more youthful appearance.

In contrast, salicylic acid is typically associated with superficial peels that target acne and oily skin, as it primarily works on the epidermis. Glycolic acid, while effective for medium-depth peels, primarily addresses issues like fine lines and texture improvements, operating at a more superficial level than phenol. Lactic acid is also known for its mild exfoliation and hydrating properties, making it suitable for lighter peels, but it does not have the same deep penetration qualities that phenol does. Therefore, phenol stands out as the chemical specifically suited for deeper exfoliation and more significant rejuvenation in deep peel treatments.
