ABSTRACT
Apple pomace is the residue left after apples are squeezed. The majority of pomace produced worldwide is produced by the apple manufacturing industry, however, most of the pomace produced by the industry is discarded. Apple pomace contains functional ingredients, such as polyphenols and triterpenoids, and exerts several beneficial effects on human health; however, studies on its cosmetic effects on the skin are lacking. Therefore, herein, we investigated the effects of apple pomace extract (APE) on human skin fibroblasts (HSFs) in vitro. When HSFs were cultured with the extract for 72 h, the number of HSFs increased at concentrations of 10 and 20 µg/mL. Transcriptome analysis and reverse transcription-quantitative PCR results revealed that the extract upregulated the expression of hyaluronan synthase (HAS) 1, HAS2, and HAS3 and downregulated the expression of HYAL1, a gene encoding the hyaluronan-degrading enzyme, in HSFs. Additionally, enzyme-linked immunosorbent assay revealed increased amounts of factors related to skin extracellular matrix, such as type I collagen and hyaluronic acid, secreted in the culture supernatant. The western blotting results suggested that the extract induced extracellular signal-regulated kinase and protein kinase B phosphorylation in HSFs. Additionally, several GO_Terms related to mitosis were detected in the Gene Ontology analysis. This is the first study to show that APE induces the proliferation of HSFs and production of factors related to skin anti-aging.
