Science
Mechanism of Action
This botanical extract utilizes sulfated polysaccharides, such as agar-based phycocolloids, to form a breathable, protective film that prevents trans-epidermal water loss (TEWL). Furthermore, its bioactive saponins and flavonoids offer anti-inflammatory and antimicrobial support, effectively reinforcing the skin's Natural Moisturizing Factor (NMF).
Research
Clinical Evidence
Medium confidence0.3%
Key findings
- 01 Clinical assessments of red macroalgae extracts at 0.3% indicate short-term moisturizing performance comparable to 0.5% Hyaluronic Acid.
- 02 A 7-day longitudinal study demonstrated significant improvements in long-term skin hydration levels.
- 03 Safety data indicates purity levels with heavy metals maintained below 20 ppm and arsenic below 5 ppm.
Transparency
Dusting Analysis
Because it is often sold as part of a pre-diluted trade name mixture, Ceramium Kondoi Extract is frequently included at negligible percentages (below 0.1%) primarily for label claims rather than functional hydration.
The Formula
Formulation
Stability
Highly stable in aqueous solutions and emulsions; however, it is sensitive to high electrolyte concentrations which can destabilize the algal polysaccharides.
Synergies
- Saccharina Angustata Extract
- Hyaluronic Acid
- Glycerin
Conflicts
- High electrolyte concentrations
- Strong oxidizing agents
Safety
Safety Profile
While specifically classified as having insufficient data by the CIR due to a lack of species-specific systemic toxicity studies, it is generally recognized as a low-irritancy marine botanical.

Verdict
An excellent secondary hydrator that rivals Hyaluronic Acid in short-term performance, though it requires precise formulation to maintain polysaccharide stability.
