Make sure you drink plenty of water. Water is beneficial to your body in many ways. It should be no surprise that it also improves your complexion. Drinking water will help your skin get the moisture it requires. It will help your skin's elasticity as well as its general smoothness.
If you don't already have a moisturizing routine for your skin, make one. Even people with oily skin should moisturize daily to keep their skin as healthy as possible. People who already moisturize should be careful not to over moisturize. Applying moisturizer more than once a day is excessive, as well as, damaging to your skin.
Simple, natural products are far better for your skin and your pocketbook than expensive cosmetics and products. Simply cleansing your face with pure water and a gentle natural soap once a day, refreshing your skin with witch hazel, and moisturizing with pure aloe vera gel will keep your skin fresh and young!
If your skin is not in the best condition, consider using vitamin E. When applied topically vitamin E can soothe dry, rough skin. When taken orally the vitamin is a powerful antioxidant that can neutralize the harmful effects of free radicals, molecules which damage collagen causing dry skin and wrinkles.
