ABSTRACT There is a rationale for adding systemic photoprotective agents to the current photoprotection regimen. This study was designed to objectively evaluate the molecular and photobiological effects of oral administration of Polypodium leucotomos extract (PLE). In all, 22 subjects with Fitzpatrick skin phototype I to III were enrolled. On day 1, subjects were irradiated with visible light, ultraviolet (UV) A1, and UVB (using 308-nm excimer laser). Evaluation was done immediately and 24 hours after irradiation. On days 3 and 4, irradiation and evaluation process was repeated after ingestion of PLE.Clinical assessments and colorimetry data showed a decrease in UVB-induced changes in 17 of 22 subjects post-PLE administration; histology findings demonstrated such a decrease in all 22 subjects.

- Antioxidant properties
- Supports skin immunity
- Raise DNA protection from UV ray
- Increases resistance to UV rays
The fern extract inhibits the formation of free radicals and also prevents UV rays from suppressing immune function, which is important in preventing harmful cellular changes that could lead to the development of skin cancer.
Another research in the International Journal of Dermatology suggests that the extract raise the skin resistance to UV rays, working as an adjuvant for the topical sunscreen.
