BETAPHYCUS GELATINUM EXTRACT.

Valuable / BLEACHING

A nutrient-dense red algae derivative prized for its exceptional ability to create a moisture-locking 'second skin' barrier. Rich in sulfated polysaccharides, it offers a dual-action approach by providing instant hydration and long-term pigment regulation for a more resilient, luminous complexion.

humectant film-forming agent antioxidant skin-brightening barrier-reinforcement

Science

This extract utilizes carrageenans to bind with skin proteins, forming a breathable, film-forming matrix that significantly inhibits trans-epidermal water loss. Beyond barrier reinforcement, it supports the skin's Natural Moisturizing Factor (NMF) and provides anti-melanogenic benefits by suppressing tyrosinase activity to brighten uneven skin tone.

Key findings

  1. 01 Clinical evaluation demonstrated an immediate 100% increase in moisture levels upon application, with hydration remaining 20% higher than placebo after 8 days of use.
  2. 02 High-precision antioxidant testing revealed an ABTS radical scavenging IC50 of 3.64 µg/mL, indicating potent cellular protection against oxidative stress.
  3. 03 Human microcirculation assays confirmed excellent skin tolerance over a 27-day period within the 0.2-4% concentration range.
