Vitamin C, also named L-ascorbic acid, is water soluble, photosensitive and is the most important antioxidant in the hydrophilic phase.

The aim of this work is to review the existing literature and eventually to give an insight to the question whether diet actually influences the way our skin ages. 5 Remarkably, upregulation of nuclear FoxO levels suppresses cell proliferation and induces apoptosis. The expression and upregulation of the cell’s own intrinsic antioxidative enzyme systems finally do the “job” and protect the cell against accumulating and harmful cellular levels of ROS. ROS activate via stimulation of STE-like 20 protein kinase 1 (MST1) and Jun N-terminus kinase (JNK) specific phosphorylations of forkhead box class O transcription factor (FoxO transcription factors), which thereafter translocate from the cytoplasm into the nucleus and thereby induce the expression of anti-oxidative enzymes like superoxide dismutase, catalase and others. The appropriate generation of ROS (for instance after physical exercise) has beneficial cell-protective and anti-aging effects.

3, 4 To find a proper balance, this review considers the beneficial “anti-aging” effects of increased reactive oxygen species (ROS) signaling recently. The best prevention strategy against the harmful action of free radicals is a well regulated lifestyle (caloric restriction, body care and physical exercise for body), with low stress conditions and a balanced nutritional diet, including anti-oxidative rich food.įrequently researched antioxidants such as carotenoids, tocophenols and flavonoids, as well as vitamins (A, C, D and E), essential omega-3-fatty acids, some proteins and lactobacilli have been referred as agents capable of promoting skin health and beauty. Prevention is the best and most effective way to work against extrinsic skin aging effects. 2 The second is extrinsic skin aging, which we view as aged skin and is the result of external factors and environmental influence, mainly chronic sun exposure and ultraviolet (UV) irradiation but also smoking, pollution, sleep deprivation and poor nutrition. 1 The first is intrinsic skin aging, which represents chronological aging and affects skin in the same pattern it affects all internal organs. Skin aging consists of two didactically independent, clinically and biologically, distinct processes. The connection between nutrition and skin condition or rather the effect of nutrition on skin aging has been an interesting research field not only for scientists but also a common field of interest for humans throughout the years, from ancient times to nowadays.
