How does salicylic acid help with acne?

Salicylic acid is recognized for its ability to effectively treat acne primarily due to its role in encouraging skin cell turnover. This beta hydroxy acid (BHA) penetrates the pores and exfoliates the skin, helping to remove dead skin cells that can clog pores and lead to acne formation. By promoting the shedding of old skin cells and allowing for the growth of new ones, salicylic acid helps to prevent the buildup of comedones, which are a common cause of acne breakouts.

In addition to its exfoliating properties, salicylic acid can also contribute to decreasing inflammation and swelling associated with acne, while its ability to penetrate oil helps to clear out clogged pores. This multifaceted approach makes it an effective treatment for both existing acne and preventing future breakouts.
