What Laminaria Saccharina Extract is & what it does

In cosmetic formulas it acts as a skin-conditioning and humectant-type ingredient, drawing on the polysaccharides and minerals naturally present in marine algae. A notable property is its content of marine sugars and trace minerals, which is why it is often used in hydrating and replenishing formulas.

Individual sensitivities are possible, so a patch test is reasonable for very reactive skin.

Is Laminaria Saccharina Extract vegan?

Laminaria Saccharina Extract is derived from seaweed, an algae rather than an animal source, so it is generally suitable for vegan formulas. The extract and any processing aids depend on the specific manufacturer. Checking the brand's vegan labeling is the best way to confirm for a particular product.
