Exfoliation is the process of removal of removing the old, dead skin cells that cling to the skin’s outermost surface. The two types of exfoliation are mechanical and chemical. People’s opportunities for seeking dermatological assistance for a myriad of conditions, including acne, rosacea, striae, photodamage, and skin cancers have increased in recent years. Chronological aging is a process of ...

Aging is a universal and irreversible process, the skin an important feature that reflects aging of organism. Skin has been focus attention in recent years because it leads to changes individual’s external features loss many biological functions. This experiment investigated improvement effect black tea extract (BTE) on mice under D-galactose induction. After 6 weeks administration, bio-chemica...

The study of age-related changes in the physiology, biochemistry, and molecular biology of isolated skin cell populations in culture has greatly expanded the understanding of the fundamental aspects of skin aging. In modern biogerontology, the terms ‘‘cellular aging,’’ ‘‘cell senescence,’’ or ‘‘replicative senescence’’ most commonly imply the study of normal diploid cells in culture, which duri...

The Taylor et al. study in this issue suggests that long-term hormone replacement therapy helps prevent skin aging. All patients interested in preventing skin aging should regularly use sunscreens, retinoids, and oral or topical antioxidants.

ABSTRACT
 Background and Objective: Skin is a barrier that protects the body from outer environtment has cosmetic function. Aging biological process marked by deterioration of physiological function body. Collagen responsible in stability strength tissues. In recent years, oral collagen supplementation become popular because it’s distributed to peoples as an anti aging therapy. The aim thi...

Aging is a complex phenomenon, a sum total of changes that occur in a living organism with the passage of time and lead to decreasing ability to survive stress, increasing functional impairment and growing probability of death. There are many theories of aging and skin remains the largest organ of the study. Skin aging is described as a consequence of intrinsic and extrinsic factors. The most c...

The intrinsic aging process of the skin in unavoidable and depends on the passage of time per se. Among harmful environmental factors that contribute to extrinsic aging, long-term effects of repeated exposure to ultraviolet radiation are the most significant and are referred to as photoaging. Photoaging is directly correlated to the quantity of UV rays received during the course of a lifetime. ...

Recently, there has been much effort to find effective ingredients which can prevent or retard cutaneous skin aging after topical or systemic use. Here, we investigated the effects of the atomic hydrogen surrounded by water molecules, H(H2O)m, on acute UV-induced responses and as well as skin aging. Interestingly, we observed that H(H2O)m application to human skin prevented UV-induced erythema ...

Aging, and in particular aging changes skin, are increasingly giving cause for concern to the mankind, especially given fact that life expectancy is extending. Skin not only a problem concerns skin sagginess, but rather it complex caused by many factors, from immune deficiency lifestyle, which affects both maintenance of skin’s barrier function well-being stem cells support organ. The structure...

Everyone desires healthy and beautiful-looking skin. However, as we age, our skin becomes old due to physiological changes. Reactive oxygen species (ROS) is an important pathogenic factor involved in human aging. Human skin is exposed to ROS generated from both extrinsic sources such as as ultraviolet (UV) light from the sun, and intrinsic sources such as endogenous oxidative metabolism. ROS-me...
