  • Publication number: 20090142370
    Abstract: A method for preventing skin-cellular aging by using a green algae extract and a cosmetic composition containing the green algae extract are disclosed. An effective dose of the green algae extract is used to inhibit the activity of Metalloproteinase (MMP) in the fibroblast and to promote of collagens and elastins production in the fibroblast. The green algae extract can be mixed with a skin permeable cosmetic composition so that the cosmetic composition performs the effect of preventing extrinsic skin aging.

  • Publication number: 20090142369
    Abstract: A method for preventing UV-induced skin-cellular injury by using a green algae extract and a cosmetic composition containing the green algae extract are disclosed. An effective dose of the green algae extract is used to protect fibroblasts from UV-induced apoptosis. The mechanism of the disclosed method is using the green algae extract to inhibit interaction between apoptosis pathway molecules Fas/FasL so as to inhibit an adapter protein (FADD) in a death-inducing signaling complex (DISC) and in turn to inhibit caspase-3 activation and cleaved polymerase (PARP) such that irreparable damage to DNA can be prevented. The green algae extract can be mixed with a skin permeable cosmetic composition so that the cosmetic composition possesses the function of preventing skin from UV-induced injury.
