Salicylic acid is a powerful beta-hydroxy acid (BHA) that treats acne and exfoliates skin
Works best for oily and acne-prone skin types
Available in concentrations from 0.5% to 2% in over-the-counter products
Can cause skin irritation if not used correctly
Salicylic acid has become a superstar in skincare, transforming how we approach acne treatment and skin exfoliation. Derived from willow bark, this beta-hydroxy acid (BHA) has been used for decades to combat skin issues, particularly acne and clogged pores. Its unique molecular structure allows it to penetrate deep into the skin, making it more effective than many other skincare ingredients.
Unlike alpha-hydroxy acids, salicylic acid is oil-soluble, which means it can dive deep into pores to dissolve excess sebum and dead skin cells. This characteristic makes it especially powerful for treating chest acne and other stubborn skin concerns.
Salicylic acid functions as a chemical exfoliant, breaking down the bonds between dead skin cells. This process helps unclog pores, reduce inflammation, and prevent future breakouts. By penetrating deep into the skin's layers, it can address acne so itchy and persistent that traditional treatments might miss.
The ingredient works by essentially "dissolving" the connections between skin cells, allowing for more efficient skin cell turnover. This process helps remove excess oil, reduce blackheads, and minimize the appearance of pores. For individuals struggling with closed comedones, salicylic acid can be particularly effective.
The FDA approves salicylic acid in concentrations between 0.5% and 2% for over-the-counter skincare products. At these levels, most people can safely use the ingredient. However, dermatologists caution that individual skin reactions can vary.

While salicylic acid is generally safe, some individuals might experience side effects. These can include dryness, peeling, redness, and skin irritation. Those with extremely sensitive skin or potentially life-threatening skin rashes should consult a healthcare professional before use.
Pregnant women and individuals taking blood thinners should be particularly cautious. Always start with a lower concentration and patch test new products to ensure your skin tolerates the ingredient.
Experts recommend introducing salicylic acid gradually. Begin by using the product every other day and monitor your skin's response. For those with oily or acne-prone skin, daily use might be appropriate. However, individuals with dry or sensitive skin should use it more sparingly.
