Oral Naturally Derived Agents as an Adjuvant Photoprotection after Dermatologic Surgery

Abstract

To be effective in protecting against the harmful effects of ultraviolet radiation (UVR), many photoprotective strategies have been used. Inadequate physical protection, amount of topical application, and allergic reactions to topical agents are limitations associated with current photoprotective strategies. Systemic agents are an emerging alternative, providing promising protection against UVR. This chapter will thoroughly review photoprotective outcomes of oral naturally derived agents from randomized controlled trials using evidence-based method. From total 24 clinical trials with 850 participants, two categories of naturally derived agents were identified. Plant-derived agents include beta-carotene, green tea, golden serpent fern, tomato, cocoa bean, and vitamin E, whereas animal-derived products consist of nicotinamide and omega-3 polyunsaturated fatty acids. In conclusion, systemic plant and animal-derived photoprotective agents may be a promising alternative in addition to conventional photoprotection.
