We investigated the effects of red ginseng treatment on skin elasticity by assessing cellular stiffness and measuring collagen protein synthesis.MethodsHuman dermal fibroblasts were treated with red ginseng, and the resulting changes in stiffness were investigated using atomic force microscopy (AFM). Cytoskeletal changes and the mRNA expression of biomarkers of aging, including procollagens I and VII, elastin, and fibrillin-1, were investigated. Collagen in a human skin equivalent treated with red ginseng was visualized via hematoxylin and eosin staining, scanning electron microscopy, and AFM.Results and conclusionThe stiffness of fibroblasts was significantly reduced by treatment with red ginseng concentrations of ≥ 0.8 mg/mL. The F-actin to G-actin ratio decreased after treatment, which corresponded with a change in fibroblast stiffness. The storage modulus (G′) and loss modulus (G″) of skin equivalent were both lowered by red ginseng treatment. This result indicates that the viscoelasticity of skin equivalent can be restored by red ginseng treatment.Graphical abstract
