CHLAMYDOMONAS REINHARDTII EXTRACT.

Valuable / HUMECTANT, SKIN CONDITIONING

A precision-engineered microalgae derivative that serves as a biological regulator for cellular health. It leverages green biotechnology to target the pathways of 'inflammaging,' bridging the gap between deep hydration and genetic skin rejuvenation.

Anti-Aging Antioxidant Anti-Inflammatory Humectant Brightening

Science

Operates as a cellular stimulant by activating nuclear transcription factors RxR and PPAR, which are vital for lipid metabolism and cell differentiation. It suppresses pro-inflammatory cytokines NF-κB and TNF-α while inhibiting matrix-degrading enzymes—specifically collagenase, elastase, and hyaluronidase—to preserve the extracellular matrix.

Key findings

  1. 01 Concentrations of 0.1% to 0.2% provide up to 92% superoxide radical scavenging and significant inhibition of skin-degrading enzymes.
  2. 02 In vivo testing of lipid-rich versions at 1.0% to 10.0% confirms stimulation of epidermal and dermal cell proliferation to combat chronic inflammatory aging.
  3. 03 Concentrations as low as 0.05% demonstrate downregulation of tyrosinase mRNA, indicating effective pigment regulation.

Because this extract shows antioxidant activity at 0.1%, many formulas include it at 'label claim' levels. However, to achieve the primary benefit of cellular renewal and transcription factor activation, a concentration of at least 1.0% is required.

Stability

Aqueous fractions containing polysaccharides are sensitive to degradation in environments with a pH lower than 4.0. Lipid-rich semi-solid forms remain highly stable in anhydrous and emulsion systems.

Synergies

  • Niacinamide
  • Vitamin C
  • Squalane
  • Peptides

Conflicts

  • Strong oxidizing agents
  • Strong AHA/BHA exfoliants (pH < 4.0)
