There are several steps that you can take to keep skin young looking. Focusing on your overall health and well-being is a good place to start. Your diet should include enough protein, omega-3 fatty acids (fish oil is a good choice) and basic vitamins like A, C and E. A good source DermaFi supplements that I found is at: healthybodysupplements.com. These are needed for the body to build new skin-cells and for the sebaceous glands to produce sebum, the skin's natural moisturizer. Drink plenty of purified water because it helps to flush toxins from the body, some of which are secreted through perspiration. A good source that I found for this is at cleanwaterpure.com. Purified water doesn't necessarily come bottled, it can be contaminated. Using a good water filter both in the shower and kitchen is essential for good health.http://guidemesupplements.com/dermafi/
