Science
Mechanism of Action
Utilizes a physical adsorption process where the vast internal surface area of the charcoal particles creates weak Van der Waals forces. These forces act as a molecular vacuum, trapping toxins, bacteria, and lipid-based impurities within its porous matrix to be easily rinsed away.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 In vitro testing confirmed that a 3.0% concentration provides peak antimicrobial efficacy against E. coli, outperforming higher concentrations by maintaining superior molecular diffusion.
- 02 Clinical evaluation of 4.0% applications demonstrated significant deep-pore clearance and exfoliation of keratinized cells, with transient pore expansion resolving within 60 minutes.

Dusting Analysis
Often added at negligible amounts (below 0.5%) solely for visual aesthetic or 'detox' claims. Effective follicular cleansing requires a minimum of 1.0% to provide sufficient surface area for adsorption.
The Formula
Formulation
Stability
Most stable in skin-neutral environments (pH 5.5-6.0). In extract form, it is typically supplied as a glycerin-water dispersion; adsorption capacity can fluctuate based on the surrounding ionic environment.

Verdict
An exceptional physical purifier for oily and congested skin types, though its non-selective adsorption requires careful formulation to avoid deactivating other active ingredients.
