Can we find Hydrogen peroxide in pharmacies? and is it good to use as a mouthwash once a week for whitening (leave it for 2 minutes)? thanks

But I personnaly use compound containing H2O2 ( hydrogen peroxide) for teeth whitening once every 3 days but not always
You should see this with your dentist
As for the availability , you shouldn't use pure hydrogen peroxide that you can find in the pharmacy , also known as Eau oxygénée, as the concentration will differ from the one dedicated to teeth
