Science
Mechanism of Action
Porphyra 334 efficiently absorbs UV-A/UV-B energy (around 334 nm), dissipating it as harmless heat, while suppressing UV-induced ROS and MMP-1 expression. BIS-SH-DECAPEPTIDE-9 acts as a signal peptide, stimulating fibroblasts to produce collagen and elastin, enhancing cellular repair and potentially reducing wrinkles.

Key findings
- 01 A cream with 0.005% porphyra-334 neutralized UVA photodamage as effectively as a cream with 1% synthetic UVA filters and 4% UVB filters.
- 02 Porphyra-334 scavenges free radicals in DPPH and ABTS assays and reduces UVB-induced ROS generation and DNA damage in vitro.
- 03 Porphyra-334 showed similar inhibitory effects on MDI-induced adipogenesis in 3T3-L1 cells.
