Over-active glands are often the problem behind oily skin. A good cleansing routine is what helps here. Strawberries, with their vitamin C and acidic properties, will leave your skin sparkling clean. Grab a fork and four plump strawberries, a dollop of cream, or a splash of milk. Add honey too if you have it. Mash away, and spread on your face for ten minutes or so. Patch test first if you have sensitivities.
