This was scheduled to be a totally different post, a guide to product order and when it's best to put on your various lotions and potions. But, as often happens when I start diving in, it turned into a bit of a monster that seemed a little hard to digest. So while I figure out how to make that post a bit more manageable, here's some info on a fantastic little ingredient, with our modern lifestyle in mind. Why is there a photo of a person in front of a computer screen on a skin care blog? All will be explained below. :)
Phyto-Melanin (Liposhield® HEV)
What is it? A synthetic melanin made from plant-derived amino acids. It is used in skin care and cosmetics. Liposhield® HEV is the trade name. On the product label, you will see melanin or phyto-melanin.
Claims: Phyto-melanin's claim to fame is its ability to protect the skin from the damaging effects of High Energy Visible Light (HEVL) What is HEVL? It's light from a range within the visible spectrum and is emitted by everything from smartphones to flat screen TVs and tablets. (Not to be confused with UV light.) Phyto-melanin absorbs the HEV before it can penetrate the skin and cause oxidative stress, resulting in free-radical damage, premature skin aging, lines, and pigmentation.
Concerns raised: I can't find any concerns raised about this skin protectant! (Yay!)
What I've found: Its chemical structure appears to mimic our own bodies' protective melanin and also is effective in low concentrations (0.2%-0.5%). There are a number of studies referencing the damaging effects of visible light on the skin all referenced at the end of this post.
From the lab Lipo Chemicals, where this ingredient is produced:
"Lipo has conducted a study analyzing the changes in skin’s gene expression when exposed to HEV light. This study’s results indicate that HEV light may significantly affect the skin’s inflammatory cascade and its progression to healing, its barrier recovery, cell cycles and melanogenesis. Our results may explain the variety of previously described effects of HEV light on skin and shed new light on the understanding of what is believed to be the harmful impact that leads to accelerated skin aging.
Our conclusion, based on this study and other research group’s studies, is that in order to maintain skin’s health; the skin must be shielded from these wavelengths. As a result, we have developed a novel patent-pending compound that acts as an “umbrella” to shield the skin from HEV light, Liposhield® HEV Melanin."
