Science
Mechanism of Action
This extract modulates inflammatory pathways through the demonstrated inhibition of COX-2 enzyme activity, alongside a reduction in pro-inflammatory cytokines such as TNF-α and IL1-β. Its robust antioxidant capacity is attributed to a rich profile of flavonoids, tannins, kaempferol, quercetin, and various phenols, which collectively neutralize harmful free radicals. Tannins also contribute a mild antiseptic barrier on the skin. Furthermore, it accelerates re-epithelialization, promoting wound healing, and has shown antiproliferative activity against specific cell types. Certain polysaccharides present within the plant may also exert immunomodulatory effects by influencing cytokine secretion.

Key findings
- 01 Topical application of a 5-10% leaf extract cream has been anecdotally associated with relief from symptoms of eczema, psoriasis, and minor burns in small pilot studies.
- 02 In vitro analysis revealed that a 70% ethanolic leaf extract achieved a notable 48% inhibition of COX-2, indicating significant anti-inflammatory potential.
- 03 An oral administration of lyophilized juice in mice, at doses of 0.1-1 g/kg, significantly reduced acetic acid-induced writhing (ID50=631 mg/kg) and inhibited croton oil-induced ear oedema by 66% at 1g/kg, confirming both antinociceptive and anti-inflammatory activities.
- 04 Research on human pterygium fibroblasts demonstrated that at 250 μg/mL (in vitro), the extract decreased cell proliferation and the expression of pro-angiogenic and pro-fibrotic factors (VEGF and CTGF).

Formulation
Stability
The extract is commonly prepared as aqueous infusions or hydroalcoholic extracts, suggesting good solubility or dispersibility in water-based systems. While one study noted a pH adjustment to 2.4 for analytical purposes, this does not define the optimal pH range for cosmetic formulation stability.
Safety
Safety Profile
Sedum Dendroideum Leaf/Stem Extract has not been directly reviewed by the Cosmetic Ingredient Review (CIR). While generally considered well-tolerated in recommended forms, caution is advised for specific populations, including pregnant individuals and children, due to limited specific safety data.
