“Key to the fountain of youth”
The phrase on above means a popular skin care ingredient often used topically that is “Hyaluronic acid”. Skin care products containing hyaluronic acid claim to hydrate the skin.
What is hyaluronic acid?
Hyaluronic Acid (HA or hyaluronan or hyaluronate) is a type of polysaccharide called a glycosaminoglycan. Hyaluronic acid is a substance that attaches to collagen and elastin to form cartilage. It helps increase supplies of joint-lubricating synovial fluid. It is mainly found in the dermis of the skin and forms an important part of the skin matrix. It decreases with age. As we get older our bodies produce less and less hyaluronic acid. The drop in it starts at around the age of 18-20 years. But 40-50 year olds are estimated to have less than half the hyaluronic acid they had in youth. Lack of hyaluronic acid causes wrinkles on the face and may also be cause for loss of skin elasticity.
Benefits of hyaluronic acid
– Hyaluronic acid moisturizes skin from the inside out. It acts as an internal cosmetic to hydrate the skin. Hyaluronic acid can hold hundreds of times its weight in water.
– Hyaluronic acid keeps your skin young and wrinkle-free.
– Hyaluronic acid helps in the formation and maintenance of collagen fibers. Depletion of collagen causes the skin to lose its elasticity. Hyaluronic acid is effective in preventing this condition.
– Hyaluronic acid helps in maintaining the skin smooth and supple.
– As we grow old, the rate at which cell mitosis takes place decreases, thus degrading the cellular regeneration and repair process. Presence of hyaluronic acid helps in reversing the condition.
– Hyaluronic acid is also useful in eliminating acne scars and helps to fight skin inflammation and irritation.
It is often used in moisturizing and anti-wrinkle formulations. Indeed it can provide effective skin surface hydration, either alone or in combination with other moisturizing ingredients. It is often used in conjunction with vitamin C products because of its ability to help the vitamin C to penetrate effectively.
The hyaluronic acid skin creams are effective only if they reach the dermis. Similarly, effects of hyaluronic injection are observed on the area where it is injected and does not improve the overall look.
