Porphyra Umbilicalis Extract

Porphyra umbilicalis extract, more commonly known as red algae, contains a treasure trove of nutrients for skin, all of which work to help protect skin from environmental stressors that cause it to look and feel older.

Studies have shown that topical use of this edible extract can help offset the damageing cascade on and within skin that’s triggered by UV light exposure. Comparative reports have shown great synergy when Porphyra umbilicalis is paired with vitamins C and E.

A key component of this algae’s ability to help protect skin from environmental damage is micosporine like amino acids. These bioactive, heat-stable water-soluble antioxidants (chief among them are palythine, shinorine and porphyra-334) are synthesized by algae to help them survive—and thrive—in harsh environmental conditions such as constant sunlight exposure.

Research has proven that micosporine like amino acids have a special ability to neutralise UVA radiation before it can damage the plant. And it turns out this protective benefit applies to skin, making this red algae an excellent addition to sunscreens. Helping to offset UVB damage is also in this red algae’s bag of tricks.

Topical use of Porphyra umbilicalis has also been shown to reduce UV-triggered redness and help prevent water loss (dehydration) in environmentally-exposed skin.

Along with the micosporine like amino acids, other antioxidant compounds in this type of red algae include vitamins C and E, lutein, chlorophyll, beta-carotene, and fucoxanthin. This algae also contains minerals, hydrating polysaccharides, and peptides that may play a role in skin’s renewal.

Recommended use levels of Porphyra umbilicalis extract in skin care range from 1–4% as supplied in a water base. The 2021 Cosmetic Ingredient Review assessment of red algae-derived ingredients deemed Porphyra umbilicalis extract safe in the present practices of use and concentrations described in their report. There is no limit on the concentration of use.
