Pseudoalteromonas antartica Ferment Extract

Pseudoalteromonas is a genus of bacteria that encompasses dozens of species, some of which live in the most extreme environments on earth. One specific species, Pseudoalteromonas antartica, lives in possibly the most inhospitable environment on earth, the frozen soil of King George Island in Antarctica. When this bacterium is fermented, the extract contains a protein peptide composed of glycine, histidine, and lysine (chemically represented as GHK). Many skincare products on the market contain GHK peptide from various sources a they have long been proven to have a role in stimulating collagen synthesis to create more elastic and less wrinkled skin over time, as well as their ability to accelerate wound healing and improve skin hydration.

The difference with Pseudoalteromonas antartica is that the GHK amino-peptide being derived from this particular organism in conjunction with all the other phytonutrients in the fermented extract may be especially effective at reversing some of the key signs of aging in the skin through a synergistic mode of action. While more research will have to be done to directly assess how all the phytonutrients work together in the skin when topically applied, in vitro studies with this extract have shown an up to 128% increase in collage I production, an up to 81% increase in collagen IV synthesis, and an up to 31% increase in elastin generation in the skin from application of a formulation containing Pseudoalteromonas antartica fermented extract as the only active.
