Frequently asked questions
Is hydrogen peroxide safe to use on skin?
While hydrogen peroxide has antiseptic properties, it is generally not recommended for routine use on skin wounds as it can damage healthy skin cells and impair healing. It is best used under professional guidance or in very dilute, specific formulations.
Can hydrogen peroxide whiten teeth?
Yes, hydrogen peroxide is a common active ingredient in many tooth whitening products due to its ability to break down stains. However, overuse or high concentrations can lead to tooth sensitivity and gum irritation.
