Science
Mechanism of Action
Portulaca Oleracea Juice acts as a powerful antioxidant, effectively neutralizing free radicals and mitigating oxidative stress from external aggressors like pollution and UV radiation, which helps to delay cellular aging. Its robust anti-inflammatory properties significantly reduce redness, irritation, and soothe skin flare-ups, making it beneficial for sensitive, irritated, and acne-prone skin, as well as conditions like rosacea, eczema, and psoriasis. This action may involve inhibiting pro-inflammatory mediators, decreasing nerve fibers in lesioned skin, and modulating NF-κB, JAK1, and STAT3/6 signaling pathways. The ingredient also enhances skin hydration and barrier integrity by strengthening the lipid barrier, reducing trans-epidermal water loss, and acting as a humectant due to its rich polysaccharides. Omega-3 fatty acids further contribute to an improved lipid profile, supporting sustained moisture retention. Additionally, it promotes anti-aging effects by stimulating collagen production and improving skin elasticity, supported by its high content of vitamins (A, C, E), glutathione, flavonoids, and phenolic acids. These components also contribute to protection against photoaging, aid in accelerated wound healing, promote epithelialization, and enhance skin regeneration, while Vitamin C and ferulic acid contribute to brightening and fading dark spots.

Key findings
- 01 In a 3-week use study involving 46 subjects, a formulation containing 0.1% Portulaca Oleracea Extract did not cause product-related irritation. Dermatological changes in skin texture and acne were observed to be within expected physiological ranges.

Formulation
Stability
Portulaca Oleracea Juice is water-soluble and stable within a pH range of 4.5 to 6.5, with raw juice exhibiting an initial pH of approximately 5.08. It generally blends well with other ingredients without adding noticeable color or scent. However, due to the presence of potentially sensitizing constituents (terpenes), it must be formulated to be non-sensitizing.
Safety
Safety Profile
The CIR Expert Panel concluded that Portulaca oleracea-derived ingredients are safe for use in cosmetics under current practices and concentrations, provided they are formulated to be non-sensitizing. This restriction addresses the presence of potentially sensitizing terpenes.
