Benzac AC 5% Gel 40g

The 40g tube of Benzac AC 5% Gel is the size for treating larger areas such as the back, chest and shoulders, or for longer courses on the face. It contains benzoyl peroxide, the most effective and best-studied acne treatment available without a prescription, and the one that every international acne guideline recommends first for inflamed pimples. It releases oxygen inside the pore, which kills Cutibacterium acnes, the bacterium behind red, pus-filled spots, and unlike antibiotics bacteria never become resistant to it; it also reduces inflammation and has a mild peeling effect that unblocks pores. Benzac's AC formula uses acrylate copolymer beads that absorb excess oil and release glycerin to limit the dryness benzoyl peroxide causes. Applied once or twice daily to affected areas it reduces inflamed acne within weeks, and it can be combined with retinoids or antibiotics prescribed by a doctor.

Back and chest acne needs the same benzoyl peroxide treatment as the face but over a much larger area, and a small tube runs out in a week. The 40g size makes treating body acne, or keeping face acne clear over months, affordable with the treatment that guidelines recommend first.
