Science
Mechanism of Action
This ingredient functions through several key pathways. It acts as a powerful antioxidant due to its rich composition of omega-3 fatty acids, vitamins A, C, E, glutathione, carotenoids, and coenzyme Q10, effectively neutralizing free radicals and protecting against environmental stressors to support anti-aging efforts. Its significant anti-inflammatory and soothing properties stem from its ability to reduce pro-inflammatory cytokines such as tumor necrosis factor-α, interleukin-6, and interleukin-1β, thereby calming irritated, reddened, and sensitive skin. Furthermore, the presence of polysaccharides and natural moisturizing factors draws moisture into the skin, enhances water retention, and minimizes transepidermal water loss, thus strengthening the skin barrier function by promoting caspase-14 and filaggrin expression.

Key findings
- 01 In a 3-week clinical use study involving 46 subjects, 72% of whom reported sensitive skin, a formulation containing 0.1% Portulaca Oleracea Extract was assessed by dermatologists and found to be safe. A body moisturizer containing 0.1% Portulaca Oleracea Extract demonstrated no significant irritation, achieving a primary irritation index (PII) of 0.0 in a single-insult occlusive patch test with 22 subjects. Moreover, a maximization study with 26 subjects confirmed no skin sensitization potential for the 0.1% Portulaca Oleracea Extract in a body moisturizer.
