Science
Mechanism of Action
This advanced ingredient operates primarily through paracrine signaling, delivering a rich array of soluble factors including various growth factors and cytokines to target skin cells. These bioactive molecules activate key signal transduction pathways, promoting significant tissue regeneration. Specific mechanisms include increasing vascular endothelial growth factor (VEGF), enhancing the migratory capacity of keratinocytes vital for re-epithelialization, and modulating pro-fibrotic indicators like WNT10A and WNT11 to prevent excessive scarring. It also boosts KRT14 expression, a crucial marker for basal epidermal health, and influences gene expression for collagen synthesis (e.g., TGFB1, COL1A1, COL3A1, FN1) within dermal fibroblasts. Furthermore, pASC-CM improves the formation of three-dimensional endothelial cell networks, indicative of improved vascularization, and actively reduces fibrogenesis by inhibiting fibroblast differentiation.

Key findings
- 01 In vitro studies utilizing 50% pig adipose stromal cell conditioned media (pASC-CM) demonstrated diverse effects on skin cell functions, particularly promoting wound healing markers. Hypoxia pre-conditioned media (CM-Hyp) notably enhanced keratinocyte migration and KRT14 expression while decreasing pro-fibrotic WNT10A and WNT11 levels in keratinocytes. Non-hypoxia conditioned media (CM-Nor) primarily boosted collagen-related gene expression (TGFB1, COL1A1, COL3A1, FN1) in dermal fibroblasts, highlighting a differential impact based on preparation. Both forms improved endothelial network formation, crucial for tissue repair.
- 02 Further research, using human adipose-derived stem cell-conditioned medium (ASC-CM), observed that a 10% concentration effectively mitigated fibrogenesis by suppressing fibroblast differentiation. A higher 100% ASC-CM concentration significantly accelerated in vivo wound healing, achieving near complete wound closure within 14 days, underscoring its regenerative potential.

Dusting Analysis
As a conditioned media, this ingredient is a complex liquid solution containing secreted factors, not a solid or powdered raw material, and thus is not subject to 'dusting' concerns.
The Formula
Formulation
Stability
To ensure optimal stability and therapeutic efficacy, conditioned media are typically stored at ultra-low temperatures, such as -80°C, prior to formulation. Preparation often involves critical steps like centrifugation, filtration (e.g., 0.22 µm), and potential concentration for purification. Variations in manufacturing methods across studies underscore the necessity for controlled, standardized processes to achieve consistent performance.
Safety
Safety Profile
PIG ADIPOSE STROMAL CELL CONDITIONED MEDIA has not undergone direct safety review by regulatory bodies such as the CIR, SCCS, or FDA for cosmetic use. However, adipose-derived stem cell conditioned media is categorized as a 'cell-free therapy,' which inherently mitigates some safety concerns associated with direct stem cell transplantation. Preclinical studies involving pig adipose-derived stem cells and their conditioned media have generally indicated a safe profile for promoting tissue regeneration in dermal wound models.
