Esthetic Bioactivity of Lavender Essential Oil for Inner Beauty

This study attempted to unveil the scientific mechanisms of lavender essential oil (Lavandula angustilfolia) concerning its esthetic bioactive effects, such as antioxidant activity, wrinkle-care, and brightening effects. For this, the oil was diluted to the concentrations of 20%, 10%, and 5% solution (EtOH, 99.5%), and the total flavonoid contents, DPPH radical scavenging activity, ABTS radical scavenging activity, tyrosinase inhibitory activity, and elastase inhibitory activity were measured. According to the analysis of antioxidant activities, total flavonoid contents, DPPH radical scavenging activity, and ABTS radical scavenging activity revealed the highest antioxidant activity at a 20% dilution, with 93.57 mg QE/g, 89.84%, and 30.60%, respectively. In terms of brightening effects, tyrosinase inhibitory activity was 193.82%, 186.63% and 179.98% at 20%, 10% and 5% dilutions. As for wrinkle-care effects, elastase inhibitory activity was 115.29%, 88.60% and 66.58% at 20%, 10% and 5% dilutions respectively. The above results confirm the antioxidant, brightening, and wrinkle-care effects of lavender essential oil to strengthen the immune system to stay healthy and beautiful. It is anticipated that the study results would help promote lavender essential oil as a material for inner beauty.
