MACROCYSTIS PYRIFERA PROTEIN.

Valuable / SKIN CONDITIONING

Derived from giant sea kelp, Macrocystis Pyrifera Protein is a marine-sourced ingredient recognized for its potential to enhance skin hydration, support barrier function, and contribute to overall skin vitality. It is often utilized in its fermented form to unlock its full spectrum of beneficial properties for healthier-looking skin.

Science

This protein, particularly when fermented, actively supports skin health by enhancing filaggrin expression in keratinocytes and increasing beneficial skin lipids, critical for a robust barrier. It exhibits antioxidant and anti-inflammatory properties, mitigating damage and promoting stratum corneum healing, while also supporting collagen synthesis and epidermal growth for improved elasticity and regulated skin tone. Its inhibitory action on sPLA2 and NFkB pathways further reduces inflammation.

Stability

Optimal biological activity for Macrocystis pyrifera protein hydrolysates and antioxidant peptides has been observed between pH 6 and 7. The highest stability of biological activities for hydrolysates was specifically at pH 7 when stored at -20 °C, with stability tested across a pH range of 2-11.


Safety

CIR Status
Not reviewed
Sensitization risk Unknown

While the CIR Expert Panel assessed many brown algae-derived ingredients, 'MACROCYSTIS PYRIFERA PROTEIN' specifically does not have a separate, definitive CIR review status. Macrocystis Pyrifera (Kelp) Extract has been deemed safe by CIR at 0.1-1% by Paula's Choice. EWG allows 'Macrocystis Pyrifera (Kelp) Protein' in VERIFIED products under specific restrictions. The FDA lists the whole Macrocystis pyrifera seaweed as GRAS for food use, not as a cosmetic protein ingredient.
