For as long as I can remember, keeping skin young and fresh has generally involved the liberal application of various moisturizing and nourishing creams with strange-sounding ingredients and an even greater number of anti-aging claims. Spain's Nylstar has managed to bind an important component of skin with 24K gold at a nanoscale level to create NYG nanoparticles. The new nanomaterial is then integrated with nylon fibers to make something called Nylgold dermawear, which is said to have a nourishing and protective effect on the skin of the wearer.

Hyaluronic Acid is found throughout the body, and is an important component of skin. Nylstar has directly mounted molecules of Hyaluronic Acid onto a 24K Gold nanoparticle surface to form a unique new structure where each gold core is encased in a shell made up of thousands of acid molecules. The company claims that testing has shown that the microscopic binding of the acid molecules and gold nanoparticles give the wearer a kind of anti-oxidant effect, protecting the skin from free radicals present in the atmosphere.

Endor Nanotechnologies compared the Golden Hyaluronan material with common fiber and Vitamin C, and found that the nanomaterial showed 93.4 per cent antioxidant activity (with Vitamin C clocking up 100 per cent and common fiber 58.9 per cent). The nanomaterial was also used to treat cell cultures and found to increase the production of Hyaluronic Acid by 60 per cent over those treated with isolated Hyaluronic Acid.

France's Spincontrol concluded that a blind test on healthy volunteers resulted in a positive moisturizing effect after a single application of Golden Hyaluronan on forearms. Dermatological patch tests on human volunteers undertaken by EVIC Hispania in Barcelona have shown Nylstar's product to have "very good skin compatibility."

Nylstar has developed a new technique to integrate the NYG nanomaterial with nylon fibers at a density of more than four billion NYG nanoparticles per square centimeter. The company claims that when the material comes in contact with the skin, the NYG nanoparticles are delivered to the skin to produce a rejuvenating, protective and hydrating effect. The technology is also said to help the skin to generate its own Hyaluronic Acid and so recover its youth and elasticity.

NylGold dermawear is currently being made available for use in the manufacture of underwear, active wear, t-shirts, stockings and shapewear.

If such a topical delivery system works as well as the laboratory tests suggest, then we may see medical as well as cosmetic uses for such clothing in the future. We'll keep you informed of any interesting developments.
