Science
Mechanism of Action
It functions as a physical exfoliant and absorbent, lifting impurities and dead skin cells from the surface. Biologically, it contains active compounds like betulin and lupeol which inhibit tyrosinase activity to modulate melanin production and neutralize oxidative stress by reducing hydrogen peroxide and superoxide radicals.

Clinical Evidence
Medium confidence15%
Key findings
- 01 In vitro evaluation (2021) confirmed that wood-derived extracts rich in betulin significantly lower oxidative markers in acetaldehyde-treated cells.
- 02 Phytochemical reviews (2015) identify its ability to regulate melanin synthesis through tyrosinase inhibition, suggesting efficacy in hyperpigmentation protocols.
Transparency
Dusting Analysis
Because it often appears in 'forest-themed' or 'natural' marketing, it is frequently used at negligible levels (under 1%) for label claims. To achieve its functional exfoliating or significant antioxidant benefits, concentrations should ideally exceed 10%.
The Formula
Formulation
Stability
Highly stable in powder form; in emulsions, it remains as suspended particles. Formulations must stay within a skin-neutral pH range to prevent the degradation of active secondary metabolites.
Synergies
- Vitamin C
- Niacinamide
- Salicylic Acid
Conflicts
- Strong oxidizing agents
- Highly alkaline environments
Safety
Safety Profile
While not formally reviewed by the CIR, it is listed in the EU CosIng database without restrictions and is generally recognized as a safe skin-conditioning agent.
