Science
Mechanism of Action
This conditioned media initiates a multi-faceted approach to skin regeneration. Its primary active components, including specific polynucleotides (PL-PN), are proven to significantly enhance human dermal fibroblast viability and elevate pro-collagen I α1 secretion. The ingredient upregulates adenosine A2A receptor expression, thereby activating the cAMP/PKA/CREB pathway, which in turn accelerates the G1/S cell cycle transition, indicating increased cellular proliferation. Furthermore, it attenuates inflammatory and catabolic signaling by reducing nuclear NF-κB localization and downregulating crucial matrix metalloproteinases (MMP1, MMP3, MMP9, MMP13). Anabolic effects are observed through an increase in TGF-β maturation and Smad2/3 phosphorylation, alongside enhanced transcription of COL1A1, COL3A1, and elastin, collectively supporting superior collagen and elastin deposition. The composition may also include flavonoids for antioxidant defense, phenolic compounds for additional anti-inflammatory action, triterpenes for skin conditioning and moisture retention, and various growth factors that support overall skin regeneration and repair processes.

Key findings
- 01 In human dermal fibroblasts, a concentration of 1 µg/mL consistently and reproducibly elevated pro-collagen I α1 production and improved cell viability, without inducing cellular stress.
- 02 A higher concentration of 10 µg/mL also demonstrated an increase in pro-collagen I α1 production in human dermal fibroblasts.

Stability
The culture medium for Paeonia lactiflora callus was maintained at pH 5.8 during cultivation. However, the optimal pH range for the stability of the conditioned media as a cosmetic ingredient is not specifically detailed in the provided data.
Safety
Safety Profile
Comprehensive safety assessments for Paeonia Lactiflora Callus Culture Conditioned Media by regulatory bodies such as CIR, SCCS, or FDA are currently unavailable. While some safety data exists for Paeonia lactiflora root extract (PLR) suggesting its safety for cosmetic use at a 1% concentration based on the Threshold of Toxicological Concern (TTC) approach, it is crucial to note that PLR is a distinct ingredient, and its safety profile cannot be directly extrapolated to this conditioned media.
