PORPHYRA YEZOENSIS POWDER.

Valuable CAS - / VISCOSITY CONTROLLING

Porphyra Yezoensis Powder is a bioactive marine ingredient derived from red seaweed, recognized for its potent protective and regenerative properties. It actively shields skin from environmental pollutants and oxidative stress while concurrently promoting collagen synthesis and cell renewal for a healthier, more luminous complexion.

Summary

Antioxidant Anti-pollution Skin Protectant Collagen Booster Skin Brightener Anti-inflammatory Wound Healing Promoter UV Protection (Indirect)

Science

Mechanism of Action

This ingredient provides anti-pollution and antioxidant benefits by effectively reducing urban particulate matter (UPM)-induced xenobiotic response element (XRE) promoter activity and mitigating reactive oxygen species (ROS) levels within human keratinocytes. Its active compound, porphyra 334, specifically inhibits AhR-induced ROS production and decreases TRPV1 activation, thereby safeguarding the epidermis. Rich in Mycosporine-like amino acids (MAAs) such as shinorine and porphyra-334, it acts as a natural UV-protective agent by absorbing UV radiation in the 310-360 nm range and exerting antioxidant effects. Furthermore, polysaccharides like porphyran, along with MAAs, confer anti-inflammatory properties by suppressing inflammation-related gene expression in skin cells. The powder also stimulates collagen synthesis, enhances skin cell proliferation, and inhibits melanogenesis for brightening, indicating significant anti-aging and wound-healing potential.

Key findings

  1. 01 In human keratinocytes, P. yezoensis extract, at concentrations ranging from 10 to 50 μg/mL, dose-dependently reduced urban particulate matter (UPM)-induced xenobiotic response element (XRE) promoter activity and reactive oxygen species (ROS) levels, demonstrating significant anti-pollutant and antioxidant activities. Its active constituent, porphyra 334, exhibited similar protective effects.
  2. 02 Nanovesicles derived from Pyropia yezoensis (PyNVs) at 7.5 × 10^9 particles/mL significantly enhanced angiogenesis, stimulated the migration and proliferation of skin cells, and accelerated the wound healing process.
  3. 03 Extracts of Pyropia yezoensis have been shown to inhibit melanogenesis, contributing to skin brightening, and concurrently stimulate collagen synthesis, suggesting anti-aging benefits.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) has assessed red algae-derived ingredients, including Porphyra Yezoensis Powder, categorizing them primarily as skin-conditioning agents. While CIR data specifically for this powder is insufficient for a complete assessment, no toxicity was observed in acute oral toxicity studies involving Porphyra species in rats. Porphyra yezoensis is widely consumed as an edible seaweed in Asian countries, and related species are generally recognized as safe (GRAS) by the US FDA for human consumption.
