What skincare ingredient is often used to treat acne due to its antibacterial properties?

Salicylic acid is commonly used to treat acne primarily due to its antibacterial properties and its ability to penetrate the pores. This beta hydroxy acid (BHA) exfoliates the skin from within by dissolving the excess oil and dead skin cells that can clog pores and lead to acne formation. Additionally, it helps to reduce inflammation and redness associated with acne lesions, making it a highly effective treatment for those struggling with breakouts.

While glycolic acid is an effective exfoliant and can improve the overall texture of the skin, it does not have the same targeted antibacterial effect against acne-causing bacteria as salicylic acid does. Shea butter is primarily a moisturizing agent that can provide nourishment and hydration to the skin, but it may not address the underlying causes of acne. Ceramides are excellent for skin barrier repair and hydration, but like shea butter, they do not possess antibacterial properties that specifically target acne. Hence, salicylic acid is the optimal choice for treating acne effectively.
