Hyaluronic acid, also known as HA, is a natural compound found in skin that has many important functions, including holding in a moisture, providing cushioning, aiding in tissue repair, holding together the skin structural components collagen and elastin, and helping create a protective barrier against microorganisms. Super Intensive Anti-Aging Serum, 100% Pure Hyaluronic Acid, Vitamin C, Vitamin E, MSM, and DMAE moisturizes skin cells, prevents water loss, and protects the skin from dirt and other pollutants. The vitamin C found in Super Intensive Anti-Aging Serum-100% Pure HA, Vitamin C +E, MSM, and DMAE is rapidly absorbed so it won't rub or wash off and helps moisturize and increase skin hydration. It also prevents premature skin aging and brightens the skin for a more even skin tone. Vitamin E helps the healing process; it can be used to treat scars, acne, and wrinkles because it speeds up cell regeneration. It also helps your skin retain its natural moisture content and makes dull-looking skin look healthier. This creates an anti-aging effect and makes your skin look younger! DMAE lightens age spots that are commonly seen on the face, the back of hands, and arms. DMAE also has skin-tightening action that slows down the inevitable natural sagging of the skin. MSM improves hair, cuticle, nail growth and health, AND reduces the wrinkles that are associated with aging.
