Diet and Skin Aging—From the Perspective of Food Nutrition

Abstract

We regularly face primary challenges in deciding what to eat to maintain young and healthy skin, defining a healthy diet and the role of diet in aging. The topic that currently attracts maximum attention is ways to maintain healthy skin and delay skin aging. Skin is the primary barrier that protects the body from external aggressions. Skin aging is a complex biological process, categorized as chronological aging and photo-aging, and is affected by internal factors and external factors. With the rapid breakthrough of medicine in prolonging human life and the rapid deterioration of environmental conditions, it has become urgent to find safe and effective methods to treat skin aging. For diet, as the main way for the body to obtain energy and nutrients, people have gradually realized its importance to the skin. Therefore, in this review, we discuss the skin structure, aging manifestations, and possible mechanisms, summarize the research progress, challenges, possible directions of diet management, and effects of foodborne antioxidants on skin aging from the perspective of food and nutrition.

A Personalized Nutrition Plan Improves Outcomes of Facial Regeneration With Platelet-rich Fibrin Liquid Matrixes

“…Thus the additional skin aesthetics bene ts conveyed by the dietary recommendations cannot be attributed to observer bias An increasing amount of evidence suggests a protective effect of "healthy diet" on skin ageing. Current dietary recommendations promote higher intakes of fruit and vegetables and sh and PUFAs (37,38). Nevertheless, several studies over the past few years have shown that what constitutes a healthy diet for an individual depends to some extent on his or her physiology and lifestyle (39)(40)(41)(42).…”

Deschampsia antarctica extract (Edafence®) as a powerful skin protection tool against the aging exposome

“…Cosmetics can deliver different damaging compounds to our skin and are thus regularly screened not only for intrinsic toxicity but, most importantly, also for their sensitizing effect in the presence of other agents such as light radiation [37] . An additional class of external agents that can provoke skin damage are dietary components that exert metabolic stress, and byproducts of endogenous metabolism are associated with disturbed patterns of sleep and stress [5,38] . Apart from major imbalances such as insulin resistance and diabetes, which are linked to systemic inflammation [39] , high levels of certain nutrients such as carbohydrates or animal saturated fats and high-protein diets promote adverse metabolic states in otherwise "healthy" individuals and are linked to tissue aging, including skin aging [5,[39][40][41] .…”

Bioactive Compounds for Skin Health: A Review

“…Many authors stress the relationship between a suitably balanced diet and the condition of the human body, including the appearance and functioning of the skin [ 14 , 15 , 16 , 17 ] (Table 1). The intake of essential nutrients in the daily diet is extremely important for the biological processes taking place in both young and ageing skin [ 15 , 18 ]. The skin is a tissue with high proliferative potential, which is why an adequate intake of proteins, carbohydrates and fats, which are essential for cellular generation, is so important [ 18 , 19 , 20 ].…”

The overall condition of the skin—its surface texture, color, and physiological properties—results from factors such as hydration, i.e., the presence of an adequate amount of water in the stratum corneum, sebum content and surface acidity.…”

“…Research increasingly suggests that a well-balanced diet significantly affects the skin ageing process. Functional anti-ageing ingredients in food include substances involved in the synthesis and metabolism of skin components (e.g., protein peptides and essential fatty acids) and those that inhibit the degradation of skin components and maintain its structural integrity (e.g., substances regulating the expression of enzymes such as matrix metalloproteinases (MMPs) and activating protein 1 (AP-1)) [ 18 ]. Due to their ability to protect the skin from harmful UV-induced effects through their antimutagenic, antioxidant and free-radical-scavenging properties, some dietary botanicals could be useful supplements for mature skin care [ 23 , 24 ].…”
