If you’ve noticed unusual light or orange-toned spots appearing on your towels, the cause is often linked to a common skincare ingredient: benzoyl peroxide. Found in many acne treatments, this compound is highly effective for skin care but can also affect fabrics. Because it acts as an oxidizing agent, it can alter the color of textiles in a way similar to mild bleaching.
On darker towels—such as black, navy, or deep gray—this reaction may leave behind lighter areas that appear orange, yellow, or pink. This happens because the darker dyes in the fabric break down first, revealing the lighter tones underneath. A helpful way to identify the cause is by observing the color change: lighter patches typically indicate color fading, while darker spots are more likely to be standard stains.
Once this type of discoloration occurs, it cannot be reversed through washing. The fabric itself is intact, but the original dye has been altered. In some situations, traces of the product can transfer during laundry and affect other items. While benzoyl peroxide is a frequent cause, other factors such as mineral deposits from water or surface residue in humid environments can also contribute to similar marks.
To reduce the likelihood of this issue, consider using lighter-colored towels for skincare routines, especially when applying products that contain active ingredients. Rinsing thoroughly before drying your face or body can also help minimize contact with fabric. Even when discoloration happens, these towels can still be useful for everyday tasks, showing that with a few simple adjustments, you can better protect your household items and extend their usability.
