Regimen's Take

Pseudoalteromonas Exopolysaccharides were originally discovered in a marine microorganism rich in a monosaccharide that is similar to hyaluronic acid, with a similar water retention capacity. As a hygroscopic ingredient, it is an excellent hydrator that uses a mechanism to promote longer-term hydration in the skin than most ingredients. It's compatible with sensitive skin. It was first found in a rocky shore in France where there were many harsh conditions (thermals, strong waves), this polysaccharide to protect against mechanical stress, UV, prevention of dehydration. It has passed HRIPT sensitivity testing, so

TLDR

Pseudoalteromonas Exopolysaccharides (Marine Hyaluronics) are excellent for hydration, and are best delivered as part of a formula that includes multiple forms of hydration. 5% is the optimal concentration studied, but concentrations above 1% have been shown to have a better-than-placebo effect.
