Science
Mechanism of Action
This extract operates through a complex interplay of biomolecules, including essential growth factors such as Collagen type-1, Fibronectin, TGF-β1, VEGF, HGF, KGF, and bFGF. These molecules function as critical cell signaling agents, prompting fibroblast proliferation and migration—processes fundamental for new collagen synthesis and effective wound healing, which collectively counteract visible skin aging. It specifically activates neocollagenesis by stimulating dermal fibroblasts with growth factors like IGF, VEGF, and PDGF. The exosome components further fortify the skin barrier and enhance hydration by inhibiting inflammatory cytokines and boosting ceramide production. Additionally, the extract offers antioxidant benefits via the Nrf2 signaling pathway to neutralize reactive oxygen species, and exerts anti-inflammatory effects by modulating macrophage polarization. It also supports keratinocyte growth and differentiation, thereby promoting collagen deposition, epithelialization, and angiogenesis.

Key findings
- 01 A 5% concentration significantly increased skin moisture content and decreased transepidermal water loss (TEWL), concurrently improving skin whitening and reducing wrinkles. Efficacy was notably enhanced when delivered via polymersomes for superior percutaneous absorption.
- 02 Cosmetic formulations containing ASC-exosomes (tested up to 3.0 × 10^11 particles/mL) statistically reduced melanin content in human volunteers experiencing hyperpigmentation. In vitro, ASC-exosomes also demonstrated a reduction in intracellular melanin levels in melanoma cells.
- 03 When a Human Adipose-derived Stem Cell-Conditioned Solution (HACS) was applied in combination with microneedling, participants observed an average increase of 11.3% in skin elasticity and 6.5% in skin hydration over a 12-week period.
- 04 A patented cosmetic composition containing 0.5% to 20% by weight of human adipose stem cell culture fluid extract in conjunction with hyaluronic acid demonstrated efficacy in improving wrinkles.

Stability
As a protein and growth factor-rich ingredient, its active components are likely sensitive to extreme pH, high temperatures, and certain denaturing agents. The use of advanced delivery systems like polymersomes is noted to enhance stability, percutaneous absorption, and overall effectiveness.
Synergies
- Hyaluronic acid (for enhanced wrinkle improvement)
- Microneedling (to improve penetration and amplify results)
- Polymersomes (for optimized delivery and absorption)
Safety
Safety Profile
Adipose-derived stem cells and their secretomes, which comprise this extract, are subjects of active clinical research and are generally considered safe in studies. Specific regulations regarding human-derived cell and tissue culture materials for cosmetics have been implemented in regions like South Korea. While clinical applications via intradermal injections of ADSCs have demonstrated safety, ongoing studies continue to address broader considerations such as isolation, purification, potential effects on tumor growth, and compliance with varying regulatory frameworks like the FDA for wider human use.
