Effect of sun screen utilizing Porphyra-334 derived from Ocean Algae for skin protection

Abstract

One of the most effective ways of preventing skin aging is to protect the skin from UV radiation, which was identified as the primary cause of photoaging. Therefore, it is necessary to develop natural and environment-friendly materials to the human skin. This study examined the effects of MAAs extracted from Chlamydononas hedleyi on UV protection and anti-inflammation in human skin cells. The function of porphyra-334 in the skin, which was isolated and purified from MMAs mixture, was tested in terms of its UV protective ability and anti-inflammation. As a result, porphyra-334 played a role in protecting the skin from UV radiation and anti-inflammation through the suppression of COX-2 expression. These results suggest that porphyra-334 can be a useful material in cosmetic products because it can protect the skin from UV radiation and anti-inflammation.

Anti-Photoaging and Potential Skin Health Benefits of Seaweeds

“…Seaweeds-derived MAAs have also been tested for their anti-inflammatory properties in UV-irradiated HaCaT cells [ 137 ]. Porphyra-334 treatments suppressed COX-2 expression and one of the main cytotoxic mediators participating in the innate response in mammals [ 138 ].…”

Physicochemical characteristics and antioxidant activities of laver cultivars harvested at different times

“…MAAs have been reported to have antioxidant effects and protective effects against ultraviolet rays and photooxidative stress (Shick et al, 2002;Venkatraman et al, 2019;Ying et al, 2019). Particularly, shinorine and prophyra-334 isolated from microalgae not only protects against cytotoxicity caused by UV irradiation but also suppresses the expression of COX-2, an inflammationrelated gene (Cho et al, 2014;Jung et al, 2014). A recent study reported that laver contains MAAs, including shinorine and porphyra-334 (Ying et al, 2019), and these compounds have surfaced as some of the beneficial components of laver.…”
