If you’ve ever pulled a freshly washed towel out of the dryer only to notice strange orange, pink, or faded patches, you’re not alone. These marks can be confusing and frustrating, especially when they appear on newer towels you expected to last.

Many people assume the problem comes from their washing machine, detergent, or even water quality. Some think it’s rust, mold, or bacteria. But in most cases, the real cause is much simpler—and much closer to your daily routine.

Not a Stain—But a Chemical Change

What makes these marks so puzzling is how they appear. Unlike typical stains from spills or dirt, these patches develop gradually. You may not notice anything at first, but over time, the discoloration becomes obvious.

Washing the towel again doesn’t help. Changing detergents doesn’t help. Scrubbing doesn’t work either.

That’s because these aren’t traditional stains sitting on the fabric—they are chemical changes within the fabric itself.

The Real Culprit: Benzoyl Peroxide

The main reason behind these marks is an ingredient called benzoyl peroxide, commonly found in acne treatments.

It’s widely used in face washes, creams, and spot treatments because it effectively kills bacteria and reduces inflammation. However, it has one major side effect when it comes into contact with fabric—it acts as a bleaching agent.

Instead of leaving a stain, it removes color from the towel’s dye. Once the color is gone, it cannot be restored.

Why the Marks Look Orange or Pink

Many people expect bleach to leave white spots, but these patches often appear orange, pink, or yellowish. This depends on the type of dye used in the towel.

Different dyes react differently to bleaching. Some fade completely, while others shift into lighter or altered shades first. Dark-colored towels tend to show the most dramatic changes, making the discoloration more noticeable.

How It Transfers Without You Noticing

You don’t need to spill the product directly onto your towel for damage to happen.

Even small amounts of residue can transfer from your skin or hands. If your acne treatment hasn’t fully absorbed, using a towel to dry your face or hands can slowly create these patches over time.

Because this process is gradual, many people don’t immediately connect the damage to their skincare routine.

How to Prevent It

The good news is that once you know the cause, preventing it is simple.

One of the easiest solutions is to use white towels for your skincare routine. Since white fabric doesn’t rely on dye, there’s nothing to bleach.

You can also:

• Set aside specific towels just for your face
• Wait for skincare products to fully absorb before using a towel
• Wash your hands after applying treatments
• Avoid rubbing treated skin directly on colored fabrics

These small habits can make a big difference.

What to Do with Already Damaged Towels

Unfortunately, once the color is removed, it cannot be restored. Washing won’t fix it.

However, the towels are still usable. You can:

• Repurpose them for cleaning
• Use them at the gym
• Dye them a darker color (results may vary)

A Simple Explanation for a Common Mystery

In the end, these stains aren’t caused by poor hygiene or faulty appliances. They’re simply the result of a powerful skincare ingredient interacting with fabric in an unintended way.

Once you understand what’s happening, the mystery disappears—and the solution becomes easy.

With just a few small adjustments, you can protect your towels while still enjoying the benefits of your skincare routine.
