Marine extracts and biofermentations for use in cosmetics
An extract of the marine algae, Sarcodiotheca , and more particularly Sarcodiotheca gaudichaudii , is described for use in cosmetic compositions. A biofermentation of Sarcodiotheca , such as for example S. gaudichaudii , is also described. This marine bioferment is useful as a skin care active ingredient for anti-aging cosmetic applications, and particularly useful when used in combination with an extracts of red algae, such as Chondrus crispus.
