Science
Mechanism of Action
This copolymer acts as a precision sebum-normalizer by inhibiting 5-alpha-reductase, the enzyme responsible for oil production. Its unique structure allows it to provide mild keratolytic and antimicrobial effects while functioning as a skin conditioner, soothing inflammation and promoting a refined skin texture.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 A randomized, double-blind study (Fabbrocini et al., 2022) demonstrated that a 3% concentration led to a 53% reduction in acne lesions and a 53% decrease in sebum production over 8 weeks.
Transparency
Dusting Analysis
Because this ingredient is often marketed for its clinical sebum-regulating properties, concentrations below 1% may provide conditioning benefits but are unlikely to deliver the 53% reduction in lesions seen in clinical trials.
The Formula
Formulation
Stability
Highly stable in aqueous gels and sprays. Unlike pure Azelaic Acid, it does not require a low pH for solubility, allowing for formulations that respect the skin's natural physiological pH.
Synergies
- Niacinamide
- Glycerin
- Salicylic Acid
Conflicts
- Strong oxidizing agents
- High electrolyte concentrations
- Highly acidic environments (below pH 5.0)
Safety
Safety Profile
While not yet specifically reviewed by the CIR, its parent components are recognized as safe, and clinical data shows excellent tolerability even on reactive skin.
