Buy some bananas. If you already have any this is not needed
- Eat the banana, and save the peel. It will be used. Make sure that the peel is yellow/black and not green. when it has a mix of yellow and black it is usually most effective. It is not shown if green peels can treat acne.
Using the inside part of the peel, rub the infected area with it. Acne is usually red, and that means that whatever treatment you are using is not helping it very much. The inside part of the peel decays into black color as you rub due to whatever soot gets on your face, and you should replace and throw away the banana peel once it is entirely black. You should continue to do this for at least 10 minutes. After that, there is not much additional effect
Do not wash your face after rubbing. This is important. Whatever the peel is made of helps remove the infection from the skin. Only when you go to bed do you wash your face. Should you wash your face right after rubbing, whatever you did a few seconds ago now has no effect whatsoever.
Continue use. Use it every day. After one day, you should see some improvements. When acne is not red and instead is nearly the color of your skin, the infection is weakened and cannot grow anymore.
