You can use ice-cube and toothpaste for the treatment of acne.First of all when you wake up, rub the spots containing acne with an ice cube for about 10 seconds. Then, before you go to bed, do it again. DO NOT DRY IT, let it dry itself. Once it's dry, put toothpaste on it and go to bed. When you wake up, take a facecloth, wet it with COLD water and wipe off the toothpaste.This is the treatment which helped me.
