The best peels for oily skin contain salicylic acid (SA), a beta hydroxy acid that is especially effective for oily and clogged pores. Salicylic acid is lipophilic, or oil-soluble, which means it can penetrate through sebum and into the pore. This allows it to exfoliate inside oily, congested pores and help remove the buildup of sebum and dead skin cells that contributes to blackheads, clogged pores and rough texture.
This is an important advantage over alpha hydroxy acids (AHAs) such as glycolic and lactic acid. AHAs are water-soluble and work primarily on the skin's surface, making them excellent for improving dullness and surface texture. Salicylic acid is usually the better hydroxy acid when excess sebum, clogged pores and oily skin are the main concerns.
Salicylic acid peels offer benefits beyond unclogging pores. Salicylic acid has anti-inflammatory properties, can help improve post-inflammatory hyperpigmentation, and exfoliates rough surface cells to make aging skin look smoother and more even. By removing excess dead skin cells from the stratum corneum, exfoliation can also help subsequently applied skincare ingredients penetrate more effectively.
These multiple benefits make salicylic acid peels useful for all Oily Baumann Skin Types. They are particularly well suited to OSPW (Oily, Sensitive, Pigmented, Wrinkle-Prone) skin because one ingredient can address several of its major concerns: excess sebum and clogged pores, inflammation, pigmentation and uneven texture associated with aging.
Combination AHA/BHA peels can be particularly useful because the AHA exfoliates the surface while salicylic acid works within oily pores. The best peel for you also depends on whether your complete Baumann Skin Type is Sensitive or Resistant, Pigmented or Non-Pigmented, and Wrinkle-Prone or Tight.
