Why Does Hydrogen Peroxide Turn My Skin White?

February 15, 2024

Hydrogen peroxide is a popular ingredient in many beauty products, including acne treatments. It kills germs and bacteria that clog pores, helping clear up acne. However, it can also bleach the skin and leave it extremely dry. This article explores why hydrogen peroxide turns the skin white and offers ways to avoid this side effect.

Why Does Hydrogen Peroxide Turn My Skin White?

Hydrogen Peroxide (H2O2) is a compound made of two hydrogen atoms and one oxygen atom. When it comes in contact with blood, cells, or other living tissue, it breaks apart into water (H2O) and oxygen (O2). This process produces the bubbling that you see when you dab a cut with hydrogen peroxide. The H2O2 in the bubbles attacks bacteria, killing them and leaving the cuts sterile. The oxygen in the bubbles also dilutes blood, preventing smooth blood flow and causing the skin to turn white.

The white color of the skin that appears after using hydrogen peroxide is caused by a process known as capillary embolism. This process temporarily prevents blood flow to the capillaries, causing them to lose their normal color. This reaction is normally harmless and should disappear once the hydrogen peroxide breaks down and the oxygen dissipates.

However, prolonged or severe discoloration should be evaluated by a physician. If you notice that your skin is turning white after using hydrogen peroxide, it may be a sign of a more serious condition. It is important to always use a product with a low concentration of hydrogen peroxide and follow all safety precautions.
