ABSTRACT
Abstract Application of sunscreen is the most established method of protecting skin from premature aging and photoaging. In this study, the passion fruit seed extract, enriched with biologically beneficial phenolics, was formulated into sun-protective makeup product. The UVB protection of concealer mousse was found have twofold higher sun protection factor (SPF) than the liquid foundation (15.48 ± 1.60 and 5.88 ± 0.30, respectively). The SPF of concealer mousse as well as the liquid foundation containing 0.1% and 0.3% of the passion fruit seed extract were 18.75 ± 0.28, 18.99 ± 0.71 and 9.32 ± 0.88, 9.77 ± 1.37, respectively. Therefore, the concealers with a similar sun-protective efficacy (p>0.05) were included for stability test accordingly. The sun-protective efficacy did not significantly shift (p>0.05) because the 0.1% and 0.3% passion fruit extract concealers had SPF of 18.09 ± 1.48 and 18.60 ± 1.21. The concealers exhibited UVA photoprotection with a boot star rating of 4 and a critical wavelength wider than 370 nm. The safety of 0.1% passion fruit extract concealer mousse was assessed. It did not cause skin irritation when assessed in human volunteers. This sunscreen makeup product provides UVA and UVB protection and is therefore suitable for daily application.
