Recently
the researchers found that an extract of Fucus vesiculosus, which
is a type of seaweed, promotes the contraction of fibroblast-populated
collagen gels through increased expression of integrin molecules.
In this study, they investigated the effects of topical application
of an aqueous extract of this alga on the thickness and the mechanical
properties of human skin. A gel formulation that included 1% of
the extract was applied topically to human cheek skin twice daily
for five weeks. A significant decrease in skin thickness measured
by B-mode ultrasound was elicited, as was a significant improvement
in elasticity measured with a Cutometer as compared with controls.
In cheek skin, the thickness normally increases and the elasticity
usually decreases with age. These results suggest that the Fucus
vesiculosus extract possesses anti-aging activities and should be
useful for a variety of cosmetics.
