Natural Therapeutics : Anti-Photoaging by

  title={Natural Therapeutics : Anti-Photoaging by},
  author={S. Holt and E. S. Mark},
Introduction Ultraviolet radiation (UVR) in sunlight is the most important cause of skin damage and aging.'"' This form of radiation causes skin aging by several mechanisms, including free-radical generation, DNA damage, collagen breakdown, the induction of immune defects, and cell death.'-5 In addition, repeated damage to the skin by sunburn is a primarily risk factor for the development of cutaneous neoplasia, including melanoma. V^hile photoaging may be considered to be the pivotal cause of… Expand

Pine pollen for molecular encapsulation and oral delivery applications
i Abstract Molecular delivery using carriers for biological applications has been a subject of interest for the past many years, as some molecules suffer from solubility (reduced bioavailability) andExpand
Anti-Inflammatory and Anticancer Activities of Taiwanese Purple-Fleshed Sweet Potatoes (Ipomoea batatas L. Lam) Extracts
Anti-inflammatory and anticancer activities of PSFP extracts were investigated and revealed that SP extracts could induce apoptosis in MCF-7 and SNU-1 cancer cells through extrinsic and intrinsic pathway, and may have potential to be applied in nutraceutical, pharmaceutical, and food industries.

Mechanisms of photoaging and chronological skin aging.
This article reviews the current understanding and presents new data about the molecular pathways that mediate skin damage by UV irradiation and by the passage of time and reveals that chronological aging and photoaging share fundamental molecular pathways. Expand
Aging- and photoaging-dependent changes of enzymic and nonenzymic antioxidants in the epidermis and dermis of human skin in vivo.
The results suggest that the components of the antioxidant defense system in human skin are probably regulated in a complex manner during the intrinsic aging and photoaging processes. Expand
Nutritional skin care: health effects of micronutrients and fatty acids.
It was concluded that nutritional factors exert promising actions on the skin, but information on the effects of low-to-moderate doses of nutrients consumed long term by healthy individuals is obviously lacking, as are data on direct effects on basal skin properties, including hydration, sebum production, and elasticity.

Modulation of skin collagen metabolism in aged and photoaged human skin in vivo.
The results suggest that the natural aging process decreases collagen synthesis and increases the expression of matrix metalloproteinases, whereas photoaging results in an increase of collagen synthesisation and greater matrix metaloproteinase expression in human skin in vivo. Expand
Cutaneous malignant melanoma, sun exposure, and sunscreen use: epidemiological evidence
Summary Background Cutaneous malignant melanoma is the most serious form of skin cancer and accounts for about three‐quarters of all skin cancer deaths. Over the last few decades the incidence andExpand

Prospects are bright for further increases in the span of functional life and improvements in the lives of the elderly, including applications of the free radical theory of aging. Expand
Skin aging: postulated mechanisms and consequent changes in structure and function.
New insights into age-associated decrements in DNA damage repair are reviewed and different treatment options for aged skin are examined. Expand
People do not apply enough sunscreen for protection
It is suggested that people who use sunscreens containing ingredients that mainly absorb ultraviolet B spend longer in the sun because of the reduced risk of sunburn and so increase their dose of ultraviolet A radiation. Expand
Nonablative laser and light treatments: Histology and tissue effects—A Review
The purpose of this analysis is to critically evaluate what is known about histologic and tissue effects of nonablative laser therapy and suggest future directions for research. Expand

A lower ratio of omega-6/omega-3 fatty acids is more desirable in reducing the risk of many of the chronic diseases of high prevalence in Western societies, as well as in the developing countries, that are being exported to the rest of the world. Expand
