Benzoyl Peroxide
Uses of Benzoyl Peroxide
The primary use of Benzoyl Peroxide is in managing mild to moderate acne vulgaris (chronic skin condition that occurs when hair follicles become clogged with oil and dead skin cells). It belongs to the group of topical acne medications.
Besides treating acne, Benzoyl Peroxide is also used off-label for managing other skin conditions like rosacea (long-term, non-contagious skin condition that causes redness), folliculitis (skin condition that causes inflammation and infection of one or more hair follicles), and seborrheic dermatitis (chronic skin condition that causes flaky, oily, and itchy or inflamed patches of skin).
Side effects of Benzoyl Peroxide
Local skin reactions like erythema (abnormal redness of the skin), dryness, peeling
Burning or stinging sensation
Allergic contact dermatitis in rare cases
Temporary skin bleaching or discolouration of hair/fabrics
How Benzoyl Peroxide works
Benzoyl Peroxide is an antibacterial and anti-inflammatory agent.
It works by releasing free-radical oxygen that oxidises bacterial proteins in Propionibacterium acnes (the primary bacteria causing acne). This reduces the amount of P. acnes in sebaceous follicles, reducing bacterial activity. It also loosens the connections between the skin's outermost cells, promoting exfoliation. This aids in unclogging blocked pores and prevents the formation of comedones or blackheads and whiteheads. Lastly, it also has an anti-inflammatory effect. By reducing P. acnes, it decreases the production of inflammatory substances that cause redness and swelling in acne lesions. In this way, this medicine manages acne effectively.
