This study investigates the photoprotective properties of Boswellia species resin, commonlyknown as frankincense, and evaluates its potential as a natural sunscreen agent. Considering theincreasing interest in natural skincare alternatives, this research examines the ultraviolet (UV)absorption characteristics and the Sun Protection Factor (SPF) of frankincense extracts. Threedistinct formulations were prepared: a standard zinc oxide suspension, a macerated frankincenseextract, and a sonicated frankincense extract. Spectrophotometric analysis was employed todetermine the absorbance spectra in the 290-320 nm range, and SPF values were calculated usingthe Mansur equation. In addition, a preliminary phytochemical screening of the frankincense resinwas conducted to identify the presence of key bioactive compounds, including flavonoids,polyphenols, and alkaloids. Results indicated that the sonicated frankincense extract exhibited asignificantly higher SPF value than the macerated extract and the standard zinc oxide suspension.This suggests that the extraction method significantly influences the photoprotective efficacy ofthe resin. The phytochemical screening confirmed the presence of flavonoids in frankincense. Thisstudy scientifically validates the traditional use of frankincense in skincare, highlighting itspotential as a natural source of UV protection. The findings highlight the importance of extractiontechniques in optimizing the photoprotective properties of natural products.
