Science
Mechanism of Action
This ingredient functions via a dual-action pathway: it regulates sebum production—potentially through the inhibition of 5-alpha reductase and microbiota balancing—while simultaneously accelerating keratinocyte turnover. The fermentation process transforms large proteins into low-molecular-weight peptides that penetrate more effectively to boost hydration and reinforce the skin barrier.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 A 4-week clinical evaluation of a 3.0% concentration showed a 38% reduction in surface sebum and a measurable decrease in visible pore diameter.
- 02 In-vivo testing at ranges between 1.0% and 5.0% confirmed significant improvements in transepidermal water loss (TEWL) and overall barrier resilience.

Dusting Analysis
Because of its long, complex INCI name and premium 'marine collagen' marketing appeal, brands often include this at trace amounts (<0.5%) for label claims. However, clinical data suggests a minimum of 1.0% is required for barrier benefits and 3.0% for significant sebum control.
The Formula
Formulation
Stability
Highly thermolabile; peptide integrity is compromised if exposed to temperatures exceeding 40°C. Must be incorporated during the cooling phase of production.
Synergies
- Niacinamide
- Hyaluronic Acid
- Glycerin
Conflicts
- Strong oxidizing agents
- Formulations with pH > 8.0
- High-heat processing
Safety
Safety Profile
While the specific ferment filtrate is awaiting formal CIR review, its constituent components (milk proteins and fish collagen) have a long history of safe use in both topical and food-grade applications.
