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.

The role of peroxisome proliferator-activated receptor-coactivator-1 gene in skin aging

Journal of Research in Medical Sciences, 2016
Skin aging is a continuous process that exhibits fine and deep wrinkles, thin and transparent skin, loss of underlying fat, dry skin and itch, following decreased collagen and elastin synthesis.

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

In Vitro and Ex Vivo Mechanistic Understanding and Clinical Evidence of a Novel Anti-Wrinkle Technology in Single-Arm, Monocentric, Open-Label Observational Studies

Cosmetics, 2022
Skin aging is a biological process leading to visible skin alterations. The mechanism of action, clinical efficacy and tolerance of a novel anti-wrinkle technology were evaluated in two skin care products formulated for different skin types.

The Potential Anti-Photoaging Effect of Photodynamic Therapy Using Chlorin e6-Curcumin Conjugate in UVB-Irradiated Fibroblasts and Hairless Mice

Pharmaceutics, 2022
Photodynamic therapy (PDT) has been used to treat cancers and non-malignant skin diseases. In this study, a chlorin e6–curcumin conjugate (Ce6-PEG-Cur), a combination of chlorin e6 (Ce6) and curcumin via a PEG linker, was used as a photosensitizer.

Repetitive Bathing and Skin Poultice with Hydrogen-Rich Water Improve Wrinkles and Blotches Together with Modulation of Skin Oiliness and Moisture

Hydrogen, 2022
Hydrogen-rich warm water (HW) has not been verified yet for skin anti-aging effects. Daily 10 min HW (dissolved hydrogen: 338–682 μg/mL, 41 °C) bathing and skin poultice with HW-impregnated towels for 11–98 days were demonstrated to improve wrinkle ...

Evolution of Thin-Film Wrinkle Patterns on a Soft Substrate: Direct Simulations and the Effects of the Deformation History

Nanomaterials, 2022
Surface wrinkling instability in thin films attached to a compliant substrate is a well-recognized form of deformation under mechanical loading. The influence of the loading history on the formation of instability patterns has not been studied.
