Pernex AC 2.5% Gel (benzoyl peroxide 2.5%) is a common topical treatment for mild acne. It helps reduce oil, unclog pores, and fight acne-causing bacteria. It is generally safe and effective when used as directed, though people with sensitive skin, during pregnancy or breastfeeding, or with existing skin conditions should use it under medical guidance.

To treat acne and fade spots, wash your face twice daily, avoid picking pimples, and use a gentle oil-free moisturiser. A night cream with benzoyl peroxide helps clear acne, while niacinamide or vitamin C can lighten dark spots. If you have frequent breakouts or marks that do not fade, see a dermatologist.
