Abstract

The aim of this research was to determine and compare SPF of various merchandised sunscreen formulations by using UV spectrophotometer. The UV absorption of each sample was measured by using UV-Vis spectrophotometry and the final SPF was calculated by using Mansur equation. The obtained values of sunscreens with same SPF were compared. The obtained SPF values were lesser than the labelled SPF values. This study allowed us to conclude that all of the tested samples had a lower real SPF when compared with labelled SPF values, it is important that the chosen SPF be correct for each individual’s Phototype. The application of sunscreens should be done correctly and in the correct amount, around 2 g/cm2.
