SKIN, XEROSIS, LOSS OF SKIN ELASTICITY
Skin hydration was represented in terms of skin water content herein measured by Corneometer. Figure Skin hydration and skin elasticity measured at two skin sites, (According to Fig. Aside from skin hydration and elasticity, four skin wrinkle and roughness parameters were employed to directly evaluate anti-skin aging including surface, volume, Ra and Rz. As shown in Fig. Skin wrinkle parameters, (Images of skin wrinkle changes at the corner of the eye of one volunteer in test group after 60 d of application.Owing to skin aging, extracellular connective tissue components composed mainly of collagen, elastin, and hyaluronic acid are degraded resulting in loss of skin elasticity, integrity, and formation of deep skin wrinklesAnother important physiological reaction contributing to skin aging is xerosis or dry skin
