MERISTOTHECA DAKARENSIS EXTRACT.

Valuable / SKIN PROTECTING

This red algae extract, often utilized within the DERMOCEA® complex, is designed to comprehensively remodel the skin's architecture. It targets both epidermal restructuring and dermal matrix reinforcement, aiming to enhance skin firmness, volume, and hydration for a visibly revitalized complexion.

Science

Mechanism of Action

Meristotheca dakarensis extract exerts a dual-action mechanism on the skin. At the epidermal level, it promotes cellular differentiation and stimulates keratin K14 synthesis, which collectively strengthens the skin's barrier and integrity. In the dermis, its action is profound: it boosts the synthesis of crucial extracellular matrix components like Glycosaminoglycans (GAGs) and collagens I & III. Concurrently, it actively inhibits key enzymatic degraders such as MMP-1 (collagenase) and hyaluronidase, thereby preserving the integrity and abundance of these vital macromolecules. This integrated approach effectively combats major signs of aging by improving hydration, restoring volume, and increasing firmness.

Key findings

  1. 01 Clinical studies incorporating 0.5%–2% of an ingredient complex containing Meristotheca dakarensis extract demonstrated significant improvements in epidermal cell differentiation and overall skin integrity. These studies also observed enhanced dermal restructuration through increased synthesis of GAGs and collagens I & III, coupled with inhibition of MMP-1, leading to better moisturization, restored skin volume, increased firmness, and reduced sagging.
  2. 02 Ex vivo studies on human skin explants treated with a gel containing 2% of the DERMOCEA® complex over 9 days showed positive effects on epidermal thickness and the composition of dermal components, including GAGs and collagen.
