Fucus Vesiculosus Extract

Fucus vesiculosus extract is an extract obtained from the species of brown sea algae, Fucus vesiculosus, or bladder wrack. The extract is used in skincare as a soothing and emollient ingredient, as well as as a thickener.

Bladderwrack got its name from its appearance: the seaweed has round air bladders that allow it to float in seawater. It is a good source of minerals – mainly iodine – and a thick polysaccharide mucilage, which is sometimes extracted and used as a thickener and gelling agent.

When it comes to cosmetic applications, Fucus vesiculosus extract is showing some very promising properties.

One study reported that it was able to decrease skin thickness and increase the elasticity of cheek skin. In cheek skin, the thickness normally increases and the elasticity usually decreases with age, and so it is therefore possible that this extract may have some anti-aging properties.

Another study showed collagen boosting and anti-inflammatory activity, as well as a reduction in dark under-eye circles. Fucoidan, the main gel-forming polysaccharide, was also shown to be effective in the treatment of atopic dermatitis (proven in an animal model).

Overall, this is a very good prospective ingredient that seems to have varied beneficial effects on the skin.
