Science
Mechanism of Action
This extract operates through multiple pathways to enhance skin health. It exhibits potent antioxidant activity, effectively neutralizing free radicals and mitigating oxidative stress. Its anti-inflammatory properties are demonstrated by suppressing key pro-inflammatory cytokines like TNF-α, IL-4, IL-6, IL-8, and TSLP, and by inhibiting COX-2/PGE2 and NF-κB signaling pathways, leading to reduced redness and irritation. The extract also contributes to strengthening the skin's protective barrier, improves moisturization, and aids in moisture retention. Furthermore, it may stimulate collagen synthesis and prevent its degradation by inhibiting collagenase activity, while also balancing skin tone through tyrosinase inhibition for anti-melanogenesis effects. As an adaptogen, it helps skin adapt to environmental stressors, protects cells from UVB radiation damage, reduces reactive oxygen species, and promotes healthy keratinocyte growth.

Key findings
- 01 In vitro studies reveal a dose-dependent proliferative effect on HaCaT keratinocytes, with an increase in living cells by up to 150% observed at 50 µg/mL. Concentrations exceeding this level led to decreased cell viability, suggesting an optimal range for cellular growth.
- 02 Demonstrates significant antioxidant activity, achieving 63%, 67%, and 79% antioxidant ability at concentrations of 1.0, 10, and 40 mg/mL, respectively.
- 03 At 50 µg/mL, the extract significantly suppressed the production of key pro-inflammatory cytokines—interleukin-1β (by 59.67%), interleukin-8 (by 62.69%), and tumor necrosis factor α (by 68.30%)—in P. acnes-stimulated THP-1 cells, suggesting a role in mitigating acne-related inflammation. It also demonstrated anti-bacterial efficacy (Minimum Inhibitory Concentration of 0.5 mg/mL) and in vitro inhibition of UVB-induced photoaging.
Transparency
Dusting Analysis
Based on multiple in vitro studies demonstrating measurable efficacy at specific concentrations across various benefits, this ingredient is not considered to be 'dusted'. Its documented effects support its inclusion for active formulation.
The Formula
Formulation
Stability
Stable and effective within a weak acid pH range of 2.98 to 6.25 for at least 60 days in cosmetic formulations. For optimal stability during manufacturing, it is recommended to incorporate Schisandra extracts at temperatures below 40°C.
Safety
Safety Profile
No specific CIR, SCCS, or FDA safety assessment for SCHISANDRA CHINENSIS PHYTOPLACENTA EXTRACT has been established. While general Schisandra chinensis fruit extract has been noted for potential endocrine disruption due to in vitro activation of estrogen receptors, this observation is not a formal regulatory safety assessment for this specific phytoplacenta extract.
