OBJECTIVE To identify whether there is a relationship between solar elastosis and the development of wrinkles in human skin. DESIGN Wrinkle depth was measured on the forehead and lateral canthus of human cadavers using image analysis. The thickness of the dermis was measured in skin sections obtained around wrinkles and stained with Elastica-van Gieson. SETTING Gross Anatomy Section, Kagosh...

Aging as a natural phenomenon affects different parts of the human body under the influence of various biological and environmental factors. The most pronounced changes that occur on the face is the appearance of wrinkles, which are the focus of this research. Accurate wrinkle detection is an important task in face analysis. Some have been proposed in the literature, but the poor localization l...

Present day cotton garments are mostly given chemical treatments like Softening, Easy care (Wrinkle free), Antimicrobial etc. Human sweat contains chemicals and some times affects the appearances of the garments. Effect of perspiration on wrinkle free treated cotton fabric on acidic and alkaline condition has been studied during this research work. It has been observed that there is no negative...

BACKGROUND The fermented leaves and stems of Cyclopia intermedia are used to brew honeybush tea, an herbal tea indigenous to South Africa with reported anti-wrinkle effects. Wrinkle formation caused by photoaging clearly involves changes in extracellular matrix components and mechanical properties of the skin. METHODS The inhibitory effects of honeybush extract and fermented honeybush on wrin...

Introduction Wrinkle ridges are prominent structures mapped throughout Mars where they accommodate shortening above thrust faults due to planet-scale loading of the Tharsis rise and other features. Solis Planum contains some of the most distinct and well studied arrays of wrinkle ridges on Mars and is a focus of our work. Many previous studies have conducted modeling of these wrinkle ridges in ...

Neck wrinkles commonly develop owing to the aging process. However, recently, the number of patients with neck wrinkles has been increasing. Also, an increasing number of young patients have presented with this condition, possibly because of the effect of the head-down posture that they adopt when using their computer or smartphone. We report two cases of young adults with a prominent neck wrin...

Introduction: We undertook axial surface mapping of selected wrinkle ridges on Solis Planum, Mars in order to assess the subsurface geometry of blind thrusts proposed to exist beneath them. This work builds on previous work [1] that defined structural families of wrinkle ridges based on their surface morphology in this region. Although a growing consensus exists for models of wrinkle ridge kine...

A thin metallic film deposited on a compliant polymeric substrate begins to wrinkle under compression induced in curing process and afterwards cooling of the system. The wrinkle mode depends upon the thin film elasticity, thickness, compressive strain, as well as mechanical properties of the compliant substrate. This paper presents a simple model to study the modulation of the wrinkle mode of t...

Typical bilayer wrinkle systems employ soft elastomers as the substrates. In contrast, shape memory polymers have recently emerged as attractive alternatives. Besides the shape fixing capability, shape memory polymers distinguish from elastomers in that they are rigid at room temperature, but experience significant modulus drop upon heating. We hereby report unique aspects of shape memory polym...

Facial wrinkles are an undesirable outcome caused by extrinsic photodamage and intrinsic aging processes. Currently, no effective strategies are known to prevent facial wrinkles. We assessed the beneficial effects of bee-venom serum on the clinical signs of aging skin. Our results show that bee-venom serum treatment clinically improved facial wrinkles by decreasing total wrinkle area, total wri...
