Science
Mechanism of Action
This extract functions through its diverse phytochemical composition, notably flavonoids such as spinacetin and patuletin. These compounds demonstrate anti-inflammatory activity by potentially inhibiting COX-2, a key enzyme involved in inflammatory pathways. Its antioxidant capacity is evidenced by significant DPPH free radical scavenging, mitigating cellular damage from oxidative stress. Furthermore, the extract exhibits antimicrobial properties against various bacterial and fungal strains, contributing to a balanced skin microbiome.

Key findings
- 01 In vivo studies in mice (at 20 mg/kg) observed that isolated spinacetin and patuletin from E. pulcherrima demonstrated significant anti-inflammatory effects in paw edema models.
- 02 Leaves extract exhibited potential antimicrobial capacity against various isolates, tested at concentrations of 10 mg/100 µL and 20 mg/100 µL.

Dusting Analysis
Insufficient specific data is available to assess whether Euphorbia pulcherrima extract is commonly 'dusted' or at what concentrations its effects become negligible in cosmetic formulations.
The Formula
Formulation
Stability
Certain constituents, such as anthocyanins, exhibit pH sensitivity, showing different UV-Vis absorption peaks and intensified color at varying pH levels (e.g., 360 nm at pH 4 and 9.2, 430 nm at pH 13.2). While an optimal pH range for overall efficacy is not specifically documented for cosmetic application, general cosmetic product pH (typically 4.0-6.5) is usually well-tolerated by the skin and may be suitable for maintaining extract stability.
Safety
Safety Profile
Euphorbia pulcherrima (Poinsettia) is generally considered non-harmful. Isolated compounds, spinacetin and patuletin, demonstrated safety in animal toxicological studies at doses up to 200 mg/kg. However, specific safety assessments by major cosmetic regulatory bodies (CIR, SCCS, FDA) for the extract as a cosmetic ingredient have not been conducted or are not publicly available.

Verdict
Euphorbia pulcherrima extract exhibits valuable anti-inflammatory, antioxidant, and antimicrobial properties supported by mechanistic and in vivo animal data, making it a promising botanical for skin health, although more human-specific clinical efficacy and safety data are needed for precise cosmetic application guidance.
