Those mysterious orange or faded patches on your towels are not a laundry failure at all—they’re a chemical reaction. Benzoyl peroxide, a common acne-treatment ingredient, acts like a mild bleach on fabric dyes. It doesn’t leave a stain on the surface; it strips color from within the fibers themselves. That’s why rewashing, scrubbing, or switching detergents never helps: the original dye is literally gone.

The damage often happens slowly and indirectly. Residue from face washes, spot treatments, or creams transfers from damp skin or hands onto towels, especially darker ones, which then develop orange, pink, or yellowish blotches. Once you know the cause, prevention is simple. Use white or “sacrifice” towels for your skincare routine, let products fully absorb before drying off, and wash your hands after applying treatments. Ruined towels can be repurposed for cleaning or workouts, but the real win is protecting new ones by adjusting a few small habits—without giving up the acne products that work.
