Science
Mechanism of Action
This extract primarily functions as a robust antioxidant, neutralizing reactive oxygen species and safeguarding cosmetic formulations and skin cells from oxidative damage. Its high concentration of flavonoids contributes significantly to this protective effect. Insights from related Selaginella species suggest additional mechanisms, including boosting the skin's natural water-holding capacity through complex carbohydrates and stress proteins, thereby providing profound moisturizing benefits and mitigating transepidermal water loss (TEWL). Furthermore, it may contribute to anti-aging by inhibiting matrix metalloproteinase (MMP) expression and stimulating procollagen type I production, facilitating skin repair and fortifying barrier function.

The Formula
Formulation
Stability
Selaginella Pulvinata Extract is soluble in aqueous and hydroalcoholic systems, allowing for flexible formulation. Its inherent antioxidant capabilities enhance the overall stability of cosmetic products by preventing ingredient oxidation. The presence of complex carbohydrates may also contribute to improved epidermal slip and emollience, enhancing the sensory profile of formulations.
Safety
Safety Profile
While Selaginella Pulvinata Extract has not been specifically reviewed by CIR, SCCS, or FDA for cosmetic safety, it is listed by COSMILE Europe, indicating general acceptance within European cosmetic regulations. Acute oral toxicity tests in mice with 10.5% total flavonoids from the plant showed no adverse reactions or fatalities. Topical non-reactivity was observed in animal studies for a related Selaginella species, however, specific human topical safety data for Selaginella Pulvinata Extract remains unassessed.
