Science
Mechanism of Action
The powder operates primarily through Epigallocatechin Gallate (EGCG), a potent catechin that neutralizes reactive oxygen species and chelates pro-oxidative metal ions. Beyond antioxidant defense, it modulates sebum production by inhibiting androgen-sensitive lipid pathways in sebocytes and protects the dermal matrix by suppressing collagen-degrading enzymes.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 A 3% topical concentration achieved a 60% reduction in sebum secretion over an 8-week period (Bosnian Journal of Basic Medical Sciences, 2010).
- 02 Formulations at 2% demonstrated efficacy in reducing inflammatory lesions in mild-to-moderate acne (Journal of Investigative Dermatology, 2013).
- 03 Topical application at 4% significantly mitigated UVB-induced DNA damage and erythema (Experimental Dermatology, 2009).
Transparency
Dusting Analysis
While often used at trace levels (<0.5%) for label appeal or color, clinical efficacy for sebum control and acne reduction requires concentrations of at least 2-3%.
The Formula
Formulation
Stability
Highly prone to oxidative browning; stability is best maintained in acidic environments (pH < 6.0) and airless packaging.
