Yes, of course. Depending on the condition. An interesting one is toothpaste (not the gel kind, but regular old Crest paste) can be dabbed on a pimple to dry it over night. The best way to maintain great skin is through a proper diet and drinking LOTS of water. there's no proof that greasy foods lead to acne, but it certainly can't help. Simple remedies such as a honey-based mask and sea salt scrubs are great natural remedies for even some of the worst skin problems.
