Vibrio Alginolyticus Ferment Filtrate is an ingredient used in some skincare products that comes from the fermentation process of a marine microorganism called Vibrio alginolyticus. There are many different ferments found in skin care, and this one is found in products made by SkinMedica. What about this ferment make it beneficial to the skin?

In skincare, Vibrio Alginolyticus Ferment Filtrate offers several benefits: it functions as a potent antioxidant to help neutralize free radicals and protect skin from environmental damage. It also has anti-inflammatory properties to reduce skin redness and irritation. Additionally, it provides hydration by attracting and binding moisture to the skin.

V. alginolyticus is a gram-negative, aerobic bacteria that is commonly found in marine environments. The ferment from this bacteria is obtained through a laboratory fermentation process under controlled conditions.

Research has identified specific compounds in Vibrio Alginolyticus that contribute to its effects. These include polysaccharides that help hydrate skin, amino acids that nourish skin, and peptide complexes that can protect against UV radiation. 

The polysaccharides found in the Vibrio Alginolyticus ferment act as excellent humectants and moisture-binders for the skin. They pull moisture from the atmosphere and from deeper skin layers to the surface, infusing hydration into thirsty cells. These sugar-based molecules essentially attach to water molecules, softening and smoothing the skin through deep and lasting hydration. Their moisture-binding nature helps retain hydration, preventing water loss even in dry conditions for supple, dewy skin.

Vibrio Alginolyticus also produces various peptides that benefit skin by signaling to cells. Research indicates the peptide compounds in the ferment stimulate the production of structural proteins like collagen and hyaluronic acid. This helps plump the appearance of skin and reduces signs of aging related to protein breakdown like wrinkles and loss of firmness.

Vibrio Alginolyticus Ferment Filtrate’s combination of humectants, emollients, and other moisturizing ingredients make it an ideal ingredient to treat dull, dehydrated skin in need of rich hydration. By drawing moisture into thirsty skin and reinforcing the moisture barrier, products containing this ingredient can revive dreary complexions to refresh a radiant, healthy glow. The ferment filtrate can also provide relief for painfully chapped and cracked lips when incorporated into lip treatments. Its polysaccharides deeply moisturize dry flaky skin on and around lips while oligopeptides strengthen tissue to smooth and soften texture. Additionally, the filtrate’s ability to facilitate absorption can help deliver other beneficial skincare nutrients deeper where they are needed most. For this versatility, the marine bacteria extract has become a coveted component of many high-end anti-aging creams, serums and masks striving to restore youthful vitality.

Products featuring this marine bacterial ferment are great for sensitive, stressed skin in need of antioxidant protection and deep hydration. The ingredient is often found in serums, ampoules, lotions and essences targeting signs of aging like wrinkles and uneven texture.

There are no known safety issues with this cosmeceutical ingredient, however the EWG rates it as a 4.  It is not clear why the EWG rating is so high.  I cannot find any causse for alarm with this ingredient.

In summary, Vibrio Alginolyticus Ferment Filtrate helps replenish and calm skin while giving it an antioxidant boost against daily environmental aggressors that can lead to visible aging over time.
