argentum la potion infinie

Hi ho silver colloidal. I’ve been spending hours trying to find out if colloidal silver has any real benefits for the skin. Following a reader request to look at an anti-aging cream called Argentum La Potion Infinie, I have been trying to find out if there is anything to its key active ingredients.

After all, Argentum La Potion Infinie costs about $242. And although it is nice enough to use with some argan oil, shea butter and glycerin, the only thing that could justify the price is a profound belief that the two actives, colloidal silver and DNA HP, are convincing.

So I went about trying to convince myself and here’s a summary of my research:

Colloidal Silver

Colloidal silver consists of tiny silver particles suspended in liquid. It is sold as an oral supplement that, because of its anti-bacterial properties, is supposed to be effective against all manner of disease and acne. But according to the National Institutes of Health, “silver has no known function in the body.” The NIH also points out that “colloidal silver can have serious side effects.” Silver builds up in the body leading to a condition called argyria, which turns those afflicted into an alarming shade of blue. The worst thing about becoming a Blue Man is that it is permanent.

OK, but what about the topical application of colloidal silver? Well, there are topical creams that use silver sulfadiazine to increase wound-healing time. However, there seem to be a variety of studies that either say that wound healing actually worsened or that there is insufficient evidence to support the claims (source).

According to Argentum La Potion Infinie, silver regulates “skin flora,” the microorganisms that reside on the skin. Since I am not prone to skin infection, I am not sure why I would want to do this. For me, colloidal silver fails to convince.


If Argentum La Potion Infinie fails to strike gold with silver, what of its second active? DNA HP (hyper polymerised deoxyribonucleic acid) is, according to the Argentum website, a “natural marine based” ingredient. You could be forgiven for thinking that “marine-based” seems a bit vague and I am happy drill down for you. Deoxyribonucleic acid is extracted from “milt” and to save you the bother of looking that up, I can tell you this is fish semen. Lovely.

Before dismissing this as too gross to contemplate, I wanted to see what it would do but found very little solid information on it apart from some evidence that DNA HP is a free radical scavenger.  

My Take

Argentum La Potion Infinie is pleasant enough to use and I do find this cream hydrating and comfortable. However, I remain too unconvinced by the key ingredients. Silver is either useless or harmful and even its touted benefits to kill microbes on the skin seems to have dubious merit for anyone with healthy skin. And there simply isn’t enough independent research on DNA HP and its benefits for skin to justify spending well over $200 on fish semen.

In short, silver anti-aging cream may be fool’s gold .
