CERATONEIS CLOSTERIUM EXTRACT.

Valuable / SKIN CONDITIONING

A nutrient-dense microalgae derivative engineered to fortify the skin's lipid architecture and neutralize environmental oxidative stress. This marine botanical serves as a multifunctional bioactive, delivering a precise blend of essential fatty acids and specialized pigments to enhance dermal resilience.

antioxidant skin-soothing barrier-repair emollient brightening

Science

This extract utilizes a multi-pathway approach: Fucoxanthin inhibits tyrosinase for brightening and UV protection, while high levels of Eicosapentaenoic acid (EPA) reconstruct the lipid barrier to stop transepidermal water loss. Furthermore, lysophosphatidylcholines (LPC) suppress pro-inflammatory cytokines like TNF-α, and chlorophyll derivatives act as potent scavengers against reactive oxygen species and lipid peroxidation.

Key findings

  1. 01 Demonstrated a measurable increase in epidermal moisture levels via corneometry, alongside significant structural reconstruction of the skin barrier.
  2. 02 In-vitro data confirmed a notable reduction in TNF-α release, indicating anti-inflammatory performance on par with pharmaceutical-grade antioxidants.
