Science
Mechanism of Action
This ingredient operates through paracrine signaling, delivering a concentrated cargo of microRNAs—specifically gga-miR-21-5p and miR-199a-5p—directly to target cells. It triggers a dual-action response: stimulating fibroblasts to accelerate Type I collagen synthesis while simultaneously suppressing Matrix Metalloproteinases (MMPs) to prevent the degradation of existing dermal architecture.
Research
Clinical Evidence
High confidence0.0168%
Key findings
- 01 A 28-day clinical trial involving 30 subjects demonstrated that a 0.0168% concentration significantly increased collagen density and reduced both pore size and UV-induced pigmentation.
- 02 In a 60-day hair density study, an application of 4 x 10^8 EVs/mL effectively optimized the anagen-to-telogen ratio and reduced shedding.
Transparency
Dusting Analysis
Because this is a high-potency biological signaling agent, it is effective at ultra-low concentrations (e.g., 0.0168%). However, because it is an expensive biotech ingredient, products that do not specify concentration or EV count may be using it at sub-functional levels for marketing claims.
The Formula
Formulation
Stability
Highly thermolabile; bioactivity degrades rapidly above 40°C. Best maintained between 15-30°C. Due to the fragile nature of growth factors, open-air stability is limited to approximately 14 days in standard essence formulations.
Synergies
- Hyaluronic acid
- Non-denaturing humectants
- Isotonic buffers
Conflicts
- High concentrations of denaturing alcohol
- L-Ascorbic Acid (low pH)
- Strong oxidizing agents
- Extreme alkaline environments
Safety
Safety Profile
Listed in the 2025 EU Glossary of Common Ingredient Names. While clinical trials show zero adverse irritation, it lacks a formal CIR safety assessment due to its recent introduction to the market.

Verdict
An exceptionally potent regenerative agent with proven results at low concentrations for both skin densification and hair growth, though it requires strict temperature control and airless packaging to maintain bioactivity.
