How does salicylic acid help treat acne?

Salicylic acid is effective in treating acne primarily because it penetrates pores to dissolve excess oil. This ability is crucial in acne treatment as it helps to unclog pores, which can become blocked with excess sebum and dead skin cells, leading to the formation of acne lesions. By breaking down the oil and debris within the pore, salicylic acid reduces the likelihood of blockages that can contribute to acne outbreaks.

Additionally, salicylic acid has mild exfoliating properties that help to promote the turnover of skin cells, further preventing clogging and leading to clearer skin over time. Its keratolytic action aids in reducing inflammation and redness, making it a popular choice in both over-the-counter and prescription acne treatments.
