Unlike topical applications, the systemic intake of these substances would allow them to reach the deeper layers of the skin, with greater effectiveness in contrasting the aging of this tissue. Nutricosmetics are becoming more and more established in the field of skin care, with continuous development of products dedicated to improving skin health and beauty. Although there are some examples of studies that have given preliminary positive results in this sense, it is important that the consumer asks himself questions when deciding to approach mineral waters with added collagen, to avoid a waste of resources or even negative effects. It is said that true beauty comes from within, and for some time this concept has also made its way into the cosmetic field, giving birth to nutricosmetics, with the consequent development of a new market sector.
Over time, a large number of beauty foods or drinks came to being, food supplements or functional foods that boast cosmetic properties with visible aesthetic results. Undoubtedly one of the leading sectors in this field, and in cosmetics in general, is that of skin health and beauty, with particular reference to anti-aging products. Over time, the skin’s structure changes due to intrinsic and extrinsic aging, which significantly alters its appearance and, in some cases, even its function. The skin appears less elastic and thicker and becomes drier and more wrinkled. In particular, the epidermis thins and becomes more permeable, with uneven pigmentation. Sebaceous glands are less active, and cell renewal slows, leading to a buildup of dead cells in the stratum corneum.
