UV Protection by Natural Products: C. myrrha Oil Versus Sunscreen.


Exposure to various types of ultraviolet (UV) radiation from the sun has been linked to skin cancer. Use of sunscreen can reduce the damaging and carcinogenic effects of UV radiation. However, multiple chemicals in sunscreen can trigger allergic responses, making people less inclined to use sunscreen. Thus, finding natural, plant-based alternatives to sunscreen with similar efficacy has become an important area of research. Myrrh oil, extracted from the shrub Commiphora myrrha, has been used in the treatment of topical wounds and studies have shown that it may provide protection against solar radiation. This study sought to further investigate if C. myrrha oil can confer protection against UV radiation. A UV-sensitive strain of Saccharomyces cerevisiae was grown in petri dishes with one half covered by aluminum foil and the other half covered by clear polyethylene food wrap. The polyethylene half was treated with either SPF 15 or SPF 30 sunscreen, C. myrrha oil or a combination of C. myrrha oil and either sunscreen. The plates were exposed to sunlight. Colony death was quantified using visual estimation. While UV blocking by C. myrrha oil alone was not as effective as that by the synthetic sunscreen, the 1:1 combination of C. myrrha oil and SPF 15 sunblock was significantly more effective than SPF 15 sunblock alone to prevent S. cerevisiae death. These data suggest that naturally-based sunscreens supplemented with synthetic UV deterrents may provide a more holistic approach to prevent UV-induced skin damage.
