Many of the systemic causes of acne are addressed by this multifunctional ingredient, which has keratolytic and anti-inflammatory activity. Its primary advantage is as an exfoliant, assisting in the dissolution of the top layer of stratum corneum cells, thus enhancing the appearance and feel of the skin. Since it is lipid-soluble, it has the potential to penetrate the pore lining and exfoliate both inside and outside the pore, making it particularly good for reducing breakouts, like blackheads and whiteheads. It has antimicrobial and antiseptic properties, improves the activity of preservatives, and can be used to change the pH of formulas.

It also helps improve skin wrinkles, roughness, and skintone in the treatment of ageing skin. Furthermore, it is an effective ingredient in products used to treat psoriasis, calluses, corns, and warts—all conditions characterised by a build-up of dead skin cells. It is reported to penetrate 3 to 4 mm into the epidermis when applied topically. A trace amount of salicylic acid can be converted into copper salicylate, a potent anti-inflammatory. Salicylic acid, when used in high concentrations, can cause skin redness and rashes.

Salicylic Acid, unlike AHAs, is naturally photoprotective. However, we recommend that you use sunscreen as your first line of defence against UV rays.
