Skin is the largest organ, performing several functions, including protecting from invasion by foreign substances and serving as the transfer point for the release of toxins from bodies. Facials are deep skin treatments that cleanse, rehydrate and rejuvenate the skin, apart from minimizing skin blemishes, acne, dry skin and, of course, wrinkles. Facials vary depending on skin type, the kind of treatment chosen, the products used and the person's age. However, it is advisable to start having facials in late 20's.
