Summary

Skin conditioning Antioxidant Soothing Barrier-restoring Moisturizing Viscosity controlling Thickening Texture enhancer

Science

Mechanism of Action

This extract functions on the skin through several key components. Its rich content of tocopherol (Vitamin E), B vitamins, and Vitamin A provides robust antioxidant protection. Skin-conditioning fatty acids like oleic and linoleic acids contribute to its emollient and moisturizing effects, while alginates offer viscosity control and textural enhancement. The ingredient also demonstrates a soothing action and aids in the restoration of the skin's barrier, with manufacturer claims suggesting benefits in epidermal vitality, collagen synthesis, and maintaining elasticity.

Key findings

  1. 01 A topical formulation containing Macrocystis Pyrifera Ferment (MPF-Serum) demonstrated a significant increase in skin moisturization by 14% after 4 weeks and 16% after 8 weeks of twice-daily application (p≤0.05). Concurrently, barrier integrity was enhanced, indicated by an 11% reduction in Transepidermal Water Loss (TEWL) at week 8 (p≤0.05). The precise concentration of the pure juice extract within the MPF-Serum was not specified.

Stability

The biological activities, including antioxidant capacity, of Macrocystis pyrifera protein hydrolysates exhibit optimal stability at pH 7.0, with diminished activity observed at pH values outside this range (e.g., 2, 5, 9, 11). Its alginate content also serves as a texture enhancer and provides viscosity-controlling properties.
