Helioguard™ 365
A natural UV-screening active to protect against photo-aging
Helioguard™ 365 is based on mycosporine-like amino acids from the red alga Porphyra umbilicalis, which are the most powerful UV-absorbing substances known to nature.
Helioguard™ 365 is both a natural and safe UV-screening compound. It is ideal for everyday use and ensures the skin is protected from photo-aging.
The red algae Porphyra (Porphyra umbilicalis) is an organism that lives in shallow water or on the beach where it is exposed to extreme UV radiation. It produces the most powerful UV-absorbing substances in nature. The isolated mycosporine-like amino acids absorb maximally at 335 nm with a molar absorption coefficient of 45,000.
