Salicylic acid CAS:69-72-7

It works by penetrating the skin and dissolving the "glue" that holds skin cells together, effectively exfoliating the skin and unclogging pores.  This makes it an effective treatment for acne, as it can help reduce breakouts and blackheads.  Salicylic acid is also used to treat various skin conditions, such as psoriasis, calluses, and dandruff.  Additionally, it is utilized in anti-aging products to improve skin texture and tone, as well as to reduce the appearance of fine lines and wrinkles.  Its ability to exfoliate and promote skin renewal makes it a versatile ingredient in the field of skincare and dermatology.
