What ingredient is commonly used as an antiseptic in acne treatment products?

Benzoyl peroxide is recognized for its effectiveness as an antiseptic in acne treatment products. This ingredient works by introducing oxygen into the pores, which helps to kill the bacteria responsible for acne, specifically Propionibacterium acnes. The antibacterial properties of benzoyl peroxide make it particularly beneficial for treating active acne lesions, reducing inflammation, and preventing new breakouts.

In addition to its antibacterial qualities, benzoyl peroxide also has mild exfoliating effects, which can aid in the shedding of dead skin cells and prevent clogged pores, further combating the formation of acne. This dual action—both as an antiseptic and exfoliant—helps in managing and improving skin clarity.

While salicylic acid is commonly used for its ability to exfoliate and deep clean pores, and glycolic acid serves as an effective exfoliant to improve skin texture and tone, they do not possess the same antiseptic properties as benzoyl peroxide. Witch hazel, on the other hand, is often used for its astringent and soothing qualities but lacks the powerful antibacterial action that benzoyl peroxide provides, which is essential for treating acne effectively.
