Science
Mechanism of Action
This extract operates through a multifaceted mechanism, primarily as an antioxidant and soothing agent. Rich in bioactive compounds like flavonoids, saponins, and Polypodine A, it actively protects skin cells from oxidative stress induced by hydrogen peroxide in vitro and mitigates enzyme-related damage. It enhances the skin's capacity to resist stress and signs of aging, while also stimulating keratinocyte differentiation and contributing to cellular repair. Furthermore, its humectant properties, particularly from saponins, contribute to maintaining a healthy, hydrated skin barrier and softening the skin.

Key findings
- 01 Demonstrated 18.9% cytoprotective activity in 3T3 fibroblast cells, effectively mitigating H2O2-induced oxidative stress in an in vitro model.
- 02 Achieved 26.5% cytoprotective activity in 3T3 fibroblast cells against H2O2-induced oxidative stress in vitro. However, cytotoxicity was observed at this concentration in 3T3, HaCaT, HeLa, and HepG2 cell lines.
- 03 A gel formulation of the extract was more effective than control in promoting wound healing in an excisional wound model in mice, indicated by improved vascular organization, epidermis, and granulation tissue formation.

Safety Profile
Generally considered safe for topical use, with no known reported side effects. In in vitro studies, no cytotoxic effects were observed at concentrations up to 0.1%, although cytotoxicity was noted at 0.2% in some cell lines (3T3, HaCaT, HeLa, HepG2). SkinSAFE categorizes Polypodium Vulgare Rhizome Extract as 'Teen SAFE,' 'Baby SAFE,' 'Eyelid SAFE,' and 'Irritant Free.' It is important to note that direct contact with the plant's leaves (not the root extract) can potentially cause a rash.
