Can hydrogen peroxide whiten skin?

Hydrogen peroxide has long been thought to gently whiten skin, as the hydrogen peroxide in its formula and its exfoliating properties stimulate collagen production, and its antibacterial properties have even been thought to help reduce acne breakouts.

However, a few years ago, using it on the face was no longer recommended because, according to Healthline, “doctors found it could cause dangerous complications” such as dermatitis, redness, hives, burns, blisters, and irritation. “More serious risks are associated with higher concentrations and longer-term use.”

That’s why they recommend avoiding facial exposure to hydrogen peroxide, especially around the eye area.

A 2005 Wiley Library study noted that for hydrogen peroxide to whiten skin, the concentration needs to be between 20 and 30 percent, “well above the 3 percent considered safe for home use.” So you may not notice a big difference when you use it, but if you do it regularly you increase your risk of burns and scarring.

That said, if you want to give it a try, even taking into account everything we’ve already mentioned, here’s what we recommend:

Test a small area: Before applying hydrogen peroxide to your face, do a patch test on an inconspicuous area of ​​your skin to make sure there are no adverse reactions.

Dilution: Mix hydrogen peroxide with water in a 1:3 ratio to reduce its concentration and avoid irritation.

Pre-cleanse: Make sure skin is clean before use.

How to use: Use a cotton swab to apply mixture to desired area, avoiding contact with eyes and lips.

Rinse: After a few minutes, rinse thoroughly with warm water and apply your favorite moisturizer.


When using hydrogen peroxide on your skin, you must follow the rules and first consult a professional.


Always choose a low concentration of hydrogen peroxide (3%) to minimize the risk of irritation.
