Effect of Ferulago lutea (Poir.) Grande Essential Oil on Molecular Hallmarks of Skin Aging

With the increase in global life expectancy, maintaining health into old age becomes a challenge, and research has thus concentrated on various strategies which aimed to mitigate the effects of skin aging. Aromatic plants stand out as promising sources of anti-aging compounds due to their secondary metabolites, particularly essential oils (EOs). The aim of this study was to ascribe to Ferulago lutea EO several biological activities that could be useful in the context of skin aging. The EO was obtained using hydrodistillation and characterized by gas chromatography-mass spectrometry (GC/MS). The anti-inflammatory potential was assessed using lipopolysaccharide (LPS)-stimulated macrophages. The effect on cell migration was disclosed using scratch wound assay. Lipogenesis was induced using T0901317, hyperpigmentation with 3-isobutyl-1-methylxantine (IBMX) and senescence with etoposide. Our results show that the EO was characterized mainly by alpha-pinene and limonene. The EO was able to decrease nitric oxide (NO) release as well as iNOS and pro-IL-1 beta protein levels. The EO promoted wound healing while decreasing lipogenesis and having depigmenting effects. The EO also reduced senescence-associated beta-galactosidase, p21/p53 protein levels and the nuclear accumulation of gamma H2AX. Overall, our study highlights the properties of F. lutea EO that make it a compelling candidate for dermocosmetics applications.
