Science
Mechanism of Action
It functions as a biodegradable abrasive to physically detach devitalized skin cells. Beyond exfoliation, its high concentration of edestin and albumin proteins creates a breathable film that enhances hydration, while residual linoleic acids and polyphenols provide defense against environmental oxidative stress.

Key findings
- 01 Clinical evaluation of hemp seed protein hydrolysates at 1-3% demonstrated up to a 19-fold increase in DPPH radical scavenging activity compared to standard extracts.
- 02 Studies on 5% protein isolates confirmed high water-retention capacity and film-forming properties essential for epidermal barrier maintenance.
Transparency
Dusting Analysis
Often listed at the bottom of ingredient decks for marketing appeal ('Hemp-infused'); however, concentrations below 1% fail to provide the mechanical density required for effective exfoliation or the protein threshold for barrier film formation.
The Formula
Formulation
Stability
Highly stable in anhydrous and solid formats. In aqueous formulas, the pH should be monitored closely to avoid the isoelectric point (pH 4.5-5.0), where proteins may precipitate.
Synergies
- Humectants (Glycerin)
- Gentle Surfactants
- Plant Oils
Conflicts
- Strong oxidizing agents
- High electrolyte concentrations
