The Effects of Visible Light on the Skin After Administration of Oral Polypodium Leucotomos

• Status: Unknown status
• Trial end date: 2017-04-01
• Target enrollment: 0
• Participant gender: All

Summary

Polypodium Leucotomos Extract (PLE) is a tropical fern that has antioxidative, photoprotective, chemoprotective, anti-inflammatory, and immunomodulatory properties. The antioxidative effects of PL include inhibition and scavenging of free radicals, lipid peroxidation and reactive oxygen species (ROS) such hydrogen peroxide, superoxide anion, hydroxyl radical and singlet oxygen. Visible light (400-700 nm) causes pigmentation in melanocompetent individuals and induces DNA damage in the human skin through ROS production. The goal of this study is to determine whether the administration of oral PLE has an effect on the development of visible light induced pigmentation.
