Hydrogen Peroxide

Description

Hydrogen peroxide (H2O2) is a widely used compound in skincare and dermatological applications, known for its oxidizing properties. This colorless liquid is a mild antiseptic and bleaching agent, effective in concentrations ranging from 3% to 10% for topical use. In skincare, hydrogen peroxide primarily functions as an antibacterial and exfoliating agent.

At lower concentrations, hydrogen peroxide can help cleanse minor wounds and prevent infections. It works by releasing oxygen upon contact with skin, creating a fizzing action that helps remove debris and dead skin cells. This mechanism also contributes to its ability to lighten hyperpigmentation and reduce the appearance of acne scars.

However, prolonged or excessive use of hydrogen peroxide can disrupt the skin's natural microbiome and cause irritation, dryness, or even chemical burns at higher concentrations. It's crucial to use products containing hydrogen peroxide as directed and avoid applying it to sensitive areas or open wounds.

In professional settings, dermatologists may use higher concentrations of hydrogen peroxide for specific treatments, such as chemical peels or tooth whitening procedures. These applications require careful supervision and precise application to minimize potential side effects and maximize efficacy.
