HYDROLYZED OYSTER EXTRACT.

Valuable / SKIN CONDITIONING

Hydrolyzed Oyster Extract is a bio-active marine ingredient rich in essential amino acids and minerals, meticulously processed to enhance skin hydration, fortify the epidermal barrier, and mitigate signs of photoaging. It precisely targets multiple cellular pathways to support overall skin health and resilience.

Summary

Skin Conditioning Antioxidant Anti-inflammatory Moisturizing Anti-aging Barrier Repair

Science

Mechanism of Action

This extract functions primarily as a skin conditioning agent, readily absorbed to promote a smoother, softer, and more hydrated complexion. Its mechanism of action includes enhancing skin barrier function by increasing the expression of key proteins like filaggrin, aquaporin-3, and enzymes crucial for hyaluronic acid synthesis. It exhibits significant anti-oxidant and anti-inflammatory properties. Furthermore, it actively inhibits wrinkle formation, skin thickening, and collagen degradation by downregulating matrix metalloproteinase (MMP) expression through the precise regulation of MAPK phosphorylation, concurrently reducing Reactive Oxygen Species (ROS) production and increasing pro-collagen I synthesis.

Key findings

  1. 01 Oral administration of oyster hydrolysate (OH) significantly improved skin moisturization and integrity, demonstrating anti-oxidant and anti-inflammatory properties, and enhancing skin hydration and barrier function without reported side effects.
  2. 02 A low molecular weight fraction (F1) derived from oyster protein enzymatic hydrolysate demonstrated optimal anti-photoaging effects in UVB-irradiated HaCaT cells.
  3. 03 Oral administration of oyster hydrolysate (OH) in UVB-irradiated hairless mice resulted in a quantifiable decrease in wrinkle formation, epidermal thickness, and collagen degradation.

Sensitization risk Moderate

Hydrolyzed Oyster Extract is generally considered safe for topical application in cosmetic formulations. However, there is a potential for individual reactions including skin irritation, allergic responses, redness, itching, or rash; a patch test is explicitly recommended before widespread use. Data and research specifically on topical usage during pregnancy and breastfeeding are currently limited, thus consultation with a healthcare professional is advised for individuals in these categories.
