Diet plays a critical role in the maintenance of various physiological functions in cutaneous structures. Inadequacy of a well-balanced diet gives rise to a constellation of skin manifestations, which are frequently mild and non-specific; hence, overlooked or misdiagnosed. However, it can lead to serious complications. This group of dermatoses affects both developing and developed countries. Children, in particular, are more prone due to increased demand for nutrients for growth and development, as well as negligence or inability to provide by the caretaker. The dermatologist might be the first physician to come across such patients since cutaneous features are more apparent. Hence, a strong clinical suspicion for multiple micro- or macronutrient deficiencies should be maintained since many conditions may have overlapping presentations such as xerosis, periorificial and intertriginous dermatitis, photo-distributed dermatitis, seborrheic dermatitis-like lesions, follicular hyperkeratosis, intracutaneous hemorrhages, impaired wound healing, pigmentary changes, and others including mucosal manifestations and hair and nail changes. This review article discussed an approach to nutritional dermatoses in the pediatric age group to aid in accurate diagnosis and timely treatment.

Background: Skin reflects the general health status and is not an exception in the process of aging. Intervention studies indicate that it is possible to delay skin aging and improve skin conditions through diet-based anti-aging strategies. The purpose of the current work was to review recent existing literature regarding the role of nutrition, for and against skin aging processes.Method: This review provides updates on the effects of nutrition strategies on skin aging developed during 2008-2014. Databases such as the ISI web of science, PubMed, Scopus and Google Scholar were investigated.Result: The most important role of nutrition on skin aging is by restricting the generation or activation of reactive oxygen species (ROS) which is considered as the main cause of extrinsic skin aging. Excess sugar in daily diet accelerates aging processes through the production of advanced glycation end products that inhibit proper repair of collagen fibers. Monounsaturated and omega-3 polyunsaturated fatty acids have inverse association with severe photoaging. Antioxidants such as vitamins C, A, E, carotenoids, flavonoids and botanical antioxidants such as resveratrol, curcumin and green tea polyphenols effectively decelerate this process. Zinc, selenium and copper are coenzymes of metallothioneins and glutathione that reduce intracellular oxidative stress and result in skin protection.Conclusion: The link between nutritional issues and skin aging is an interesting but conflicting subject that requires many interventional studies. Intracellular antioxidant mechanisms are the most effective protection against skin aging.
