10 Home Remedies for Cold Sores

Cover the Cold Sore

Putting a local anesthetic ointment containing benzocaine on the cold sore can also help numb the pain temporarily. However, attempting to camouflage a cold sore with makeup often aggravates the problem, as the chemicals in makeup can make the sore worse. And don't share your lipstick or makeup, either.
