Salicylic acid is widely recognized as a key ingredient in anti-acne products due to its ability to penetrate the pores and exfoliate the skin. It works by dissolving the debris that clogs pores, which helps to prevent the formation of acne. This ingredient is a beta hydroxy acid (BHA) that also has anti-inflammatory properties, reducing redness and swelling associated with acne lesions.

While glycerin is an effective moisturizer, it does not have direct anti-acne properties. Vitamin C is known for its antioxidant benefits and its role in brightening skin and helping with hyperpigmentation, but it does not primarily target acne. Tea tree oil is sometimes used in anti-acne formulations due to its antibacterial properties, but salicylic acid is significantly more common due to its exfoliating action and its proven effectiveness in treating and preventing breakouts.
