Thank you DrJ, very interesting. This is the product in question:
https://www.osmosisskincareproducts.com/Essence-17p6.htm
It is a Vitamin C powder that you mix in your hand (with serum, aloe, water etc.) It only contains LAA, L-glutathione and D-alpha tocopherol. It's a convenient way to use LAA without having to make an LAA serum etc. and seems to get very good reviews. I just wasn't sure about the L-glutathione. I like the ease of use with this product but I suppose I could do the same with just LAA powder as well. I still would like to try this product though as my first introduction into LAA.
Do you have any thoughts DrJ? I certainly wouldn't want to harm my skin by using glutathione or anything. Though I know that's probably silly. If it works good as an antioxidant then that seems ok? |
I don't think glutathione will hurt your skin at all. Whatever it doesn't need, it will adjust its own production downward. |

| And that's not detrimental in any way? Does your skin just increase production of glutathione again upon discontinuation of use? And do you know if glutathione has any lightening properties or no? |

Hi Dr J
Any news yet on the new dermastamp that you mentioned earlier? I'm thinking of starting dermarolling to get rid of deep acne scars and sunspots. I'm 50 yrs old though, is that too old to expect new collagen and elastin from dermarollilng/dermastaming ?
Thanks |

A nice open access review article on the science behind polyphenols in skin photoprotection:
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2813915/?tool=pubmed
Arch Dermatol Res. 2010 Mar;302(2):71-83. Epub 2009 Nov 7.
Skin photoprotection by natural polyphenols: anti-inflammatory, antioxidant and DNA repair mechanisms.

Abstract
Epidemiological, clinical and laboratory studies have implicated solar ultraviolet (UV) radiation in various skin diseases including, premature aging of the skin and melanoma and non-melanoma skin cancers. Chronic UV radiation exposure-induced skin diseases or skin disorders are caused by the excessive induction of inflammation, oxidative stress and DNA damage, etc. The use of chemopreventive agents, such as plant polyphenols, to inhibit these events in UV-exposed skin is gaining attention. Chemoprevention refers to the use of agents that can inhibit, reverse or retard the process of these harmful events in the UV-exposed skin. A wide variety of polyphenols or phytochemicals, most of which are dietary supplements, have been reported to possess substantial skin photoprotective effects. This review article summarizes the photoprotective effects of some selected polyphenols, such as green tea polyphenols, grape seed proanthocyanidins, resveratrol, silymarin and genistein, on UV-induced skin inflammation, oxidative stress and DNA damage, etc., with a focus on mechanisms underlying the photoprotective effects of these polyphenols. The laboratory studies conducted in animal models suggest that these polyphenols have the ability to protect the skin from the adverse effects of UV radiation, including the risk of skin cancers. It is suggested that polyphenols may favorably supplement sunscreens protection, and may be useful for skin diseases associated with solar UV radiation-induced inflammation, oxidative stress and DNA damage. |

| Does anyone know of any good resources for information on coffeeberry? I can find a lot of hype over the last few years about it being the next best thing but no real follow up. |

bumping this thread....it has some excellent info and I am providing an update....
some here know of Carol Demas, a scientist and skin researcher who used provide the only unbiased and accurate information to be found on the web (unless someone else knows of anyone new doing this)....
I seem to have located her - she is now teaching math in Gainesville, FLA....if I knew her personally, I would coach her into the skincare business.

| Well, when I read that 4.5% of tretinoin gets into the bloodstream, it does make me wonder where she gets her infopinions. |
