Porphyra Umbilicalis Extract is obtained from red alga and contains isolated mycosporine-like amino acids which are a natural defense component against UVA radiation. The isolated mycosporine-like amino acids absorb maximally at 335 nm with a molar absorption coefficient of 45'000.

Derived from natural raw material, Porphyra Umbilicalis Extract is a safe ingredient and a genuine UVA protection factor for everyday use. It protects the skin against premature aging signs preventing the appearance of lines, wrinkles, and other signs of photoaging.

In a clinical study with 20 women a test product with 5% Porphyra Umbilicalis Extract was tested against a product with 1% Butyl Methoxydibenzoylmethane and 4% Ethylhexyl Methoxycinnamate. The test areas on the forearm were irradiated twice weekly with UVA. The irradiation dose of 10 J/cm2 corresponds to an average UVA exposure at a non-protected skin site.

Porphyra Umbilicalis Extract could reduce lipid peroxidation, the primary injury of UVA irradiation, as efficiently as the product with synthetic filters. The product with Helioguard 365 prevented in this study the negative effects of UVA on skin firmness and smoothness even better than the product with synthetic filters.
