Osmosis Replenish tops up an antioxidant hit list

Sagging Skin

I have just started to test an antioxidant serum called Replenish ($38 for 30ml) by Osmosis Pur Medical. I must admit, I am very excited: the ingredients list is a veritable who's who of the antiaging, antioxidant hit list. If the ingredients are all they are cracked up to be, this is going to be one powerful potion.

First up, there is phosphatidycholine. The only other time I have come across this is in Dior Capture R60/80. Some dermatologists are experimenting with it as an alternative to liposuction since it is believed that phosphatidycholine can target and dissolve fat cells. I mentioned it in a post on mesotherapy.

It isn’t going to be easy to try to explain what phosphatidycholine is without resorting to some long words. Anyway, I shall try to keep this as simple as I can. Phosphatidycholine is the predominant phospholipid (something that is in all life forms) of all cell membranes and of the circulating blood lipoproteins. It is made up of glycerol and fatty acids. Phosphatidycholine contains choline (and this is the interesting part), therefore, it is a precursor to messenger molecules that go from cell to cell. And it can improve and protect cells and membrane damaged by free radicals.

Osmosis has ensured that it is keeping good company with vitamin B3 (niacinamide), which increases ceramide in skin and has been shown to cure acne. It is also toxic, but only at doses far higher than used in cosmetics. Then there is catalase, an enzyme that occurs naturally in our bodies (but declines as we get older) and prevents too much hydrogen peroxide from building up.

Of course, I can't resist giving a shout out to spin trap, a busy molecule that hunts down free radicals and stops them from spinning out of control. It is the signature ingredient of Your Best Face. Other old friends include GHK copper peptide. In case you were wondering, the mouthful that is tetrahydrocurcuminoids is turmeric treated somehow so that is colorless rather than bright yellow.

Ferulic acid is something of an unsung hero of the antiaging cosmetic world. A 2004 Italian study concluded that ferulic acid is a more powerful antioxidant than alpha-tocopherol (vitamin E), beta-carotene, and ascorbic acid (vitamic C). Meanwhile, Duke University researchers blended it with vitamin C and E and proclaimed it a "potent ubiquitous plant antioxidant".

The full list of remarkable ingredients is below and, best of all, there is nothing not to like. I'll report back after a few weeks of testing.

    Jana, I have done some more research on niacinamide and I don't think there is cause for concern. You can read my post on niacinamide and sirtuins here http://www.truthinaging.com/body/what-is-niacinamide-and-can-it-be-used-with-sirtuins.

    The "ethyl" you are referring to is indeed ethyl alcohol. Osmosis did try to formulate this product without alcohol - but with no success. According to Osmosis, the amount used is not signficant enough to result in any harm to the skin. The benefit is that certain active ingredients are able to dissolve in solution.

    Jana,
    Thank you for sending me back to the ingredients list on the bottle. There is a comma between ethyl and niacinamide (which I have now inserted into this post). Although this raises another question, what is ethyl? I suspect it might be ethyl alcohol. Trans-reservatrol is actually a common designation for plain old resveratrol. As to your point about niancinamide negating NAD, this is not at all clear cut. There is a lot of conflicting information, including references that niacinamide is a precurser of NAD. There are other controversies about <a href="http://www.truthinaging.com/ingredients/niacinamide/" rel="nofollow">niacinamide</a> being carcinogenic, although the studies are 20 years old. I'll spend some time trying to get to the bottom of this.

    I notice that Replenish contains both niacinamide (as ethyl niacinamide) and something called "trans-resveratrol." I've never seen the designations "ethyl niacinmide" or "trans-resveratrol," though it is my understanding that just plain resveratrol is a pro-sirtuin. And, it's my understanding that niacinamide most likely negates (i.e., suppresses) the action of sirtuins by contributing to NAD. Any thoughts, please, as I'm a bit flummoxed as to why Osmosis would use these two ingredients in one product. Thank you.
