Science
Mechanism of Action
It functions as an essential cofactor for carnitine palmitoyltransferase I, the enzyme responsible for transporting long-chain fatty acids into the mitochondria. By promoting the beta-oxidation (metabolic breakdown) of these lipids within sebocytes, it diverts fatty acids away from sebum synthesis, physically reducing oil output at the source.
Research
Clinical Evidence
High confidence2%
Key findings
- 01 A vehicle-controlled study demonstrated a 34.8% reduction in sebum secretion after 21 days of 2% concentration applied twice daily.
- 02 Combination therapy with 5% EGCG showed enhanced efficacy, reaching a 43.5% reduction in skin oiliness.
- 03 In vitro analysis confirmed concentration-dependent lipid reduction in human sebocytes via enhanced mitochondrial metabolism.
Transparency
Dusting Analysis
While often listed for its 'energy' claims at trace amounts (under 0.2%), clinical sebum suppression requires a threshold of at least 1-2%. Formulations using it for oil control should be scrutinized if the ingredient appears near the bottom of the INCI list.
The Formula
Formulation
Stability
Highly hygroscopic and heat-sensitive; must be processed below 60°C to maintain integrity.
Synergies
- Epigallocatechin Gallate (EGCG)
- Niacinamide
- Glycerin
Conflicts
- Strong oxidizing agents
- Extreme alkaline environments (pH > 8)
- High heat (>60°C)
Safety
Safety Profile
Generally recognized as safe (GRAS). It is well-tolerated even by sensitive skin types due to its natural occurrence in human metabolism.

Verdict
An exceptionally effective, non-stripping oil control agent that uses metabolic pathways rather than surface-level absorption to manage sebum.
