Herbs with Photo-Protective Properties: A Comprehensive Review
By Emilee Wright, Herbalist
Photo-protective herbs, renowned for their ability to shield the skin against harmful UV radiation emitted by the sun, have gained attention in recent years. These herbs possess an array of characteristics, such as their abundant reserves of polyphenolic substances, flavones, flavonoids, tannins, and lipid content. These constituents have a photo-protective action that serves as a barrier against potent visible light and UV rays. By absorbing UV radiation, these herbs act as nature's protective shield, safeguarding our precious skin from the harmful effects of excessive sun exposure.
Current studies suggest that the antioxidant and anti-inflammatory properties of these herbs may help protect the skin from environmental pollutants and UV radiation, which can cause premature aging and skin damage. With ongoing research and advancements in skincare science, it is possible that incorporating these herbs into sunscreen formulations could enhance their protective effects and promote healthier, more resilient skin. As scientists delve deeper into understanding the potential benefits of these natural ingredients, it opens up exciting possibilities for the future of skincare and sun protection. Further investigations are needed to explore the precise mechanisms through which these herbs can safeguard the skin and to determine the optimal concentrations for maximum efficacy. By harnessing the power of nature, we can potentially amplify the benefits of sunscreen by integrating these herbs into innovative formulations that provide even greater protection against harmful environmental factors.
In one study using herbs native to Sri Lanka, Atalantia ceylanica, Hibiscus furcatus, Leucas zeylanica, Mollugo cerviana, Olax zeylanica and Ophiorrhiza mungos, these natural ingredients were carefully examined for their potential topical use as sun protection, mainly owing to their rich antioxidant content.
it is essential to acknowledge that the scientific evidence in this specific area is still somewhat limited, I would exercise caution and refrain from solely relying on herbal extracts as a substitute for conventional sunscreen. However, with further research and a deeper understanding of their properties, it is plausible that incorporating these extracts into cosmetic sunscreen formulations may indeed enhance their overall benefits and pave the way for potentially safer and more effective options for sun protection.
