Assessing the safety and efficacy of DIY-homemade sunscreens with natural, aromatic and herbal ingredients

Sunscreen products are widely used during the summer months to protect against increased sunlight exposure. While there have been advancements in the effectiveness and safety of commercial sunscreens, there is a growing interest in "completely natural" and homemade skincare products, including sunscreens. These homemade alternatives often incorporating aromatic and medicinal herbal preparations, are being touted as safe alternatives on online social media platforms and alternative health websites. It is essential to recognize that scientific research has primarily focused on evaluating the effectiveness and safety of commercially available sunscreen products. Concerns have arisen regarding the potential risks associated with non-commercial sunscreens, particularly those labeled as "homemade" or "completely natural." Therefore, it is crucial to investigate whether these DIY sunscreen products, advertised as natural and additive-free, pose any health threats due to their inadequate sun protection properties. This study aims to examine the formulations of these proposed homemade sunscreen products, specifically evaluating their durability, protection against ultraviolet A and B (UVA and UVB) radiation, and average sun protection factor (SPF) values from a toxicological perspective. Emphasizing the importance of safety in sunscreen products is paramount, as the use of unsafe sunscreens can lead to serious health risks, including skin cancer, premature aging, and other skin disorders.
