Mint has many healing properties when it comes to acne, so it’s no surprise that toothpaste is a popular home remedy to treat unsightly pimples. It is important to use the right kind of toothpaste: a white paste that contains hydrogen peroxide or baking soda. The combination of these ingredients can help to reduce acne-causing bacteria and relieve pain caused by inflammation. Toothpaste can be very drying, and it’s also very messy, so this remedy works best for occasional spot treatment. Simply apply a thin layer to the pimple and leave on overnight, rinsing thoroughly the next morning.
