Gold is the new black given just about every other investment is enfeebled by the economy. It might be a better bet than government bonds, but other than a gold tooth – an acquired taste – should gold be considered an essential part of your beauty arsenal. Every now and then cosmetic formulators venture into alchemy and go for gold (E’shee, Nutra-Lift and just the other day it was mentioned in our interview with Cherie Dobbs, founder of Dermastart's Prana range). But I can’t help but wonder: what is its true value in skincare?
Prana has a serum called Prana AU 24K Gold ($96.00 at TIA shop) and I am just starting to test it. Cherie Dobbs says that “gold works with our own body makeup and helps with blood flow and oxygen”. I haven’t been able to find any specific evidence for that but claims for the medicinal benefits of gold date back many of thousands of years and ancient Indian, Egyptian and Chinese medicine used gold-based medicinal preparations for such ailments as smallpox, skin ulcers and measles.
The use of gold compounds in medicine is called chrysotherapy. One of its modern applications is the soothing arthritic symptoms. Gold salts (the ionic chemical compounds of gold) are injected to reduce inflammatory conditions such as arthritis. Gold nano-bullets are being used, according to Science magazine, as a cure for cancer. And isotope gold-198 is used in some cancer treatments and other diseases.
As far as skincare is concerned, gold is said to minimize collagen depletion and boost elasticity. There’s even a gold thread face lift in which a 24K gold mesh framework is inserted permanently under the surface of the skin where it is supposed to stimulate collagen production which then plumps and firms up the skin and reduces wrinkles.
I can’t find independent research on gold and improving the skin, but there might be a clue to gold’s plausibility as an anti-ager in its used against arthritis. This is an inflammatory disease and chronic inflammation is believed to one of the causes of aging. So, theoretically, gold could help the skin by being an anti-inflammatory.
Except that the mechanism by which gold drugs operate to treat arthritis is a matter of scientific debate. Harvard Medical School thinks it’s not an anti-inflammatory and that gold works by making the proteins associated with autoimmune diseases inactive. Other theories are that gold helps in the transportation of drugs to their sites of action.
Also there’s much debate around the kill or cure theme. Once absorbed into the cell, gold is proposed to be linked to anti-mitochrondrial activity and induced cell apoptosis, so it might be affecting healthy cells as well as unhealthy ones. On the other hand, research indicates there’s an anti-inflammatory action from ionic gold nanoparticales with little or no toxicity. Although research on rats had less positive results. ). After a lot of burrowing around on academic websites, I did turn up some evidence that gold salts boost collagen lll.
All this contradictory research is a bit frustrating. As is finding out that the most common reaction to oral gold medication for rheumatoid arthritis is, ironically, a skin rash (source).
