Which ingredient is often used to treat acne?

Salicylic acid is renowned for its effective treatment of acne due to its unique properties. It is a beta hydroxy acid (BHA) that penetrates the pores, effectively exfoliating the skin and helping to clear out excess oil and debris that can lead to acne breakouts. By penetrating deep into the follicle, salicylic acid helps to prevent clogged pores, which is a primary cause of acne.

Furthermore, salicylic acid possesses anti-inflammatory properties, which can reduce the redness and swelling associated with acne lesions. This makes it particularly beneficial for those with acne-prone skin, as it not only treats existing breakouts but also helps to prevent future ones.

While glycolic acid also aids in exfoliation, it primarily works on the surface of the skin rather than inside the pores, making salicylic acid a more targeted choice for acne treatment. Vitamin C is primarily known for its antioxidant benefits and brightening effects, while hyaluronic acid is renowned for its moisturizing properties but does not directly address acne.
