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