The aim of this article is to assess the current evidence for using plant-based natural products as sunscreens. Human skin contains an antioxidant defense system to deal with sun exposure, but excessive UV radiation can tax the body’s natural defense mechanisms leaving skin vulnerable to free radical damage. For this reason, we often require supplemental protection in the form of sunscreen. Consumer interest in natural products continues to rise, driving research on natural plant-based sunscreens.
Oils and extracts from plants (such as raspberries, coconuts, pomegranates, and green tea), offer a wide range of UV protection not only for themselves but also potentially for humans, with SPF levels ranging from 2 to 56. But while published research on plant-based UV protection of humans is showing promise, investigations are still in their infancy. Learn about the science behind natural oils as a sunscreen and the reason why commercial sunscreens are still important.
Natural oils are becoming more popular for topical use. This activity explores the scientific evidence for the use of natural oils in sun protection.
