Researchers at Stony Brook University charged with developing skin tissue for burn victims and various wound therapies, conducted a study that was recently published in the journal, Nanotoxicology. Inasmuch as nanoparticles of gold are often included in various over-the-counter skincare products, the researchers wanted to see if gold's properties might speed healing, as claimed by skincare manufacturers whose products contain it. Unfortunately, gold wasn't a winner. It appears that gold nanoparticles essentially speed the aging process and increase the appearance of wrinkles by inhibiting cell division, motility (ability to move) and collagen growth.
According to the researchers, the most disturbing finding was that the particles interfered with genetic regulation, RNA expression, and impaired the cells' ability to mature. “Reductions caused by gold nanoparticles can result in systemic changes to the body,” said Professor Mironava, one of the researchers. “Since they have been considered inert and essentially harmless, it was assumed that pure gold nanoparticles would also be safe. Evidence to the contrary is beginning to emerge.”
Further, the gold particles were shown to inhibit adiponectin, a protein involved in regulating glucose levels and fatty acid breakdown, which helps to regulate metabolism.
This appears to be an obvious challenge to, if not a warning about, using skincare products that contain gold. Our Atlanta plastic surgery practice offers both Obagi® and SkinMedica® because we've found both lines extremely effective and yet safe for our cosmetic patients.
