Benzoyl peroxide, a common active ingredient in acne treatments, is a potent oxidizer widely found in products like PanOxyl, Clearasil, Neutrogena, and prescription-strength creams, prized for its ability to reduce inflammation and kill bacteria.
Although highly effective on skin, benzoyl peroxide has a notorious side effect: it reacts strongly with fabrics. On towels.
It can break down dyes and fibers, leaving behind orange, yellow, or pale patches that seem impossible to remove. Dark-colored towels—especially black, navy, deep gray, or charcoal—are particularly vulnerable.
The chemical strips the surface dyes, revealing lighter undertones. Once this oxidation occurs, normal laundering or stain treatments cannot restore the original color.
