A single-center, randomized, double-blind, placebo-controlled study on the efficacy and safety of “enzyme-treated red ginseng powder complex (BG11001)” for antiwrinkle and proelasticity in individuals with healthy skin

Journal of Ginseng Research, 2016
Background: During the aging process, skin shows visible changes, characterized by a loss of elasticity and the appearance of wrinkles due to reduced collagen production and decreased elasticity of elastin fibers.

Numerical model for prediction of wrinkling behavior on a thin-membrane structure

Mechanical Engineering Journal, 2014
One of the key aspects of developing gossamer space structures is the prediction of wrinkles and slacks in the material. Wrinkles, which essentially refer to elastic buckling, have been analyzed numerically using finite element methods (FEMs) with shell ...

Evaluation of Aging Effects on Skin Wrinkle by Finite Element Method

Journal of Biomechanical Science and Engineering, 2008
The reason why the wrinkle suddenly becomes prominent at a middle age is addressed from biomechanical standpoint. The multistage buckling theory we have derived concludes that the sudden enlargement of wrinkle comes from a switch of the specific buckling
