Spectrophotometric absorption spectra (a) and determination of the Sun Protection Factor (SPF) spectrophotometric (b) of NV-HA and standards (quercetin and benzophenone-3). Results are expressed as mean ± SD (), where , Nv-HA 1.0% versus quercetin 10 mg/L), , Nv-HA 0.5% versus quercetin 10 mg/L), , Nv-HA 1.0% versus benzophenone-3 10 mg/L), , Nv-HA 1.0% versus Nv-HA 0.5%), and , benzophenone-3 10 mg/L versus quercetin 10 mg/L), according to one-way ANOVA followed by Tukey’s test.
