Science
Mechanism of Action
Primarily functions via Chlorella Growth Factor (CGF) to stimulate cellular turnover and tissue regeneration. It acts as a potent antioxidant by neutralizing reactive oxygen species (ROS) through its carotenoid and chlorophyll content. Furthermore, it inhibits matrix metalloproteinase-1 (MMP-1), elastase, and collagenase—enzymes responsible for degrading the skin's structural integrity—while suppressing pro-inflammatory NF-κB pathways.
Research
Clinical Evidence
High confidence3.3%
Key findings
- 01 Topical application between 1-5% demonstrates significant improvements in skin hydration and wound healing over 28 days via collagen stimulation.
- 02 A 3.3% concentration provides a verified biological defense against cytotoxicity and oxidative stress caused by PM2.5 atmospheric pollution.
- 03 In-vitro data confirms that concentrations as low as 0.0005% begin inhibiting MMP-1 to prevent dermal matrix degradation.
Transparency
Dusting Analysis
While microscopic amounts can inhibit certain enzymes in vitro, a minimum of 1% is required to see the clinically validated benefits in skin hydration and barrier repair. Many products include it at trace levels (<0.1%) purely for 'superfood' marketing claims.
The Formula
Formulation
Stability
Exhibits high thermal stability up to 80°C. However, the chlorophyll content is highly sensitive to UV light, necessitating opaque or UV-protected packaging to maintain potency.
Synergies
- Hyaluronic acid
- Vitamin C
- Ferulic Acid
Conflicts
- Strong oxidizing agents
- Highly acidic formulations below pH 3.5
