Nano Gold Effectiveness
How science is backing up the effectiveness of Nano Gold?
In the Center for Sustainable Nanotechnology has motivated, study gold nanoparticle interactions with biological systems. Companies boast that gold improves skin tone and elasticity, provides anti-aging benefits and improves blood circulation. Well, how exactly do gold nanoparticles provide all of these benefits?
That’s a great question, but before we proceed, a crash course in skin science might be useful.
Skin is composed of three main layers: the epidermis, dermis and hypodermis. The epidermis is the outermost skin layer and it mainly comprises dead cells that we continuously shed. There is a constant generation of new cells, with the newest cell found in the deeper layers and the older cells found on the outermost layer. It is the dermis that supports the epidermis and contains our hair follicles, oil, sweat glands, muscles, nerves and blood vessels. The dermis also contains connective tissues, mostly made of collagen and elastin.
Carbohydrates are one of main fuel sources for your body and are found in fruits, vegetables, bread and many other foods. The accumulation of AGEs in the skin causes the skin to lose some of its elasticity.4 Understanding how the accumulation of AGEs affects skin elasticity leads us to the role of gold in cosmetics. Gold nanoparticles are able to compete with carbohydrates to bind to amino acids like lysine and arginine. With gold particles taking up the place where carbohydrates would otherwise bind, the formation of AGEs should therefore be inhibited, and fewer wrinkles should form on the skin.3,4
