Salicylic acid is widely recognized as one of the most effective ingredients for treating acne-prone skin due to its ability to penetrate the pores and exfoliate from within. It is a beta-hydroxy acid (BHA) that helps to dissolve excess sebum (oil) and unclog pores, which are critical steps in preventing and treating breakouts. Additionally, salicylic acid has anti-inflammatory properties that help to reduce redness and swelling associated with acne lesions.

The other options, while they may have benefits for skin health, do not target acne in the same manner. Glycolic acid, an alpha hydroxy acid (AHA), is primarily used for surface exfoliation, making it more effective for issues like hyperpigmentation and improving skin texture, rather than specifically addressing the deeper causes of acne. Hyaluronic acid is best known for its exceptional hydrating capabilities and is often used to retain moisture in the skin, but it does not have the acne-fighting properties of salicylic acid. Tea tree oil is a natural antibacterial agent that can help with acne to some extent; however, it is not as consistently effective or scientifically supported as salicylic acid in treating acne-prone skin.
