Cutaneous ageing is a complex biological phenomenon consisting of two components; intrinsic ageing, which is largely genetically determined and extrinsic ageing caused by environmental exposure, primarily UV light. In sun-exposed areas, these two processes are superimposed. The process of intrinsic skin ageing resembles that seen in most internal organs and is thought to involve decreased proli...
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. Panax ginseng Meyer has been used as a traditional medicine for various diseases due to its wide range of biological activities including skin protective effects. Ginsenosides are the ...
Today, the valuable metabolites of microalgae are widely used in the production of many cosmetic products, as the biomass of algae contains pigments, proteins, essential fatty acids, polysaccharides, vitamins and minerals, all of which are present in both natural foods and cosmetics are used. In fact, these secondary metabolites with anti-blemish and anti-microbial, anti-aging, sunscreen and sk...
BACKGROUND Facial aging is a concern for many patients. Wrinkles, loss of volume, and discoloration are common physical manifestations of aging skin. Genetic heritage, prior ultraviolet light exposure, and Fitzpatrick skin type may be associated with the rate and type of facial aging. Although many clinical trials assess the correlates of skin aging, there is heterogeneity in the outcomes asses...
INTRODUCTION Glycation products accumulate during aging of slowly renewing tissue, including skin, and are suggested as an important mechanism underlying the skin aging process. Adipose-derived cells are widely used in the clinic to treat ischemic diseases and enhance wound healing. Interestingly, adipose-derived stem cells (ASCs) are also effective in anti-aging therapy, although the mechanism...
Topical skin care regimens are a mainstay treatment for aging skin. All patients seeking skin rejuvenation can benefit from this low-risk intervention. This article reviews available nonprescription topical treatments for rejuvenation including moisturizers, antioxidants, retinols, and sunscreen.
Hair cycling is modulated by factors both intrinsic and extrinsic to hair follicles. Cycling defects lead to conditions such as aging-associated alopecia. Recently, we demonstrated that mouse skin exhibits regenerative hair waves, reflecting a coordinated regenerative behavior in follicle populations. Here, we use this model to explore the regenerative behavior of aging mouse skin. Old mice (>1...
Aging of skin is an intricate biological process consisting of two types. While intrinsic or chronological aging is an inevitable process, photoaging involves the premature aging of skin occurring due to cumulative exposure to ultraviolet radiation. Chronological and photoaging both have clinically differentiable manifestations. Various natural and synthetic retinoids have been explored for the...
The conditions in which we live nowadays contribute to exposure of our bodies to harmful factors such as UV radiation, pollution, smoking, poor eating habits, low physical activity, stress, which thereafter lead to the acceleration of skin aging process. In women, the process is additionally dependent on the menopause, as a result of the disappearance of hormones, the process is faster. Physiol...
During aging, the reduction of elastic and collagen fibers in dermis can lead to skin atrophy, fragility, and aged appearance, such as increased facial wrinkling and sagging. Microfibril-associated glycoprotein-1 (MAGP-1) is an extracellular matrix protein critical for elastic fiber assembly. It integrates and stabilizes the microfibril and elastin matrix network that helps the skin to endure m...
