The influence of dietary supplements on the skin: radiance and youth

Section 1: Leather – Mirror of Inner Health

The skin, the largest organ of the human body, plays a vital role in protection against external influences, temperature regulation and synthesis of vitamin D. However, its condition is also a reflection of internal health. The lack of nutrients, stress, hormonal malfunctions and environmental factors can negatively affect its appearance, leading to dryness, dullness, rashes, premature wrinkles and other problems. In this regard, biologically active additives (dietary supplements) gain more and more popularity as a means of maintaining skin health from the inside.

1.1 structure and skin functions

Understanding the structure of the skin is the key to understanding how dietary supplements can affect its condition. The skin consists of three main layers:

Epidermis: The upper layer responsible for the barrier function. Consists of keratinocytes, melanocytes (responsible for pigmentation) and Langerganes cells (immune defense). Constantly updated, dropping dead cells.
Dermis: The middle layer containing collagen, elastin and hyaluronic acid, which provide elasticity, elasticity and moisturizing the skin. It also contains blood vessels, nerve endings and hair follicles.
Hypoderm (subcutaneous fat fiber): The lowest layer, consisting mainly of adipose tissue. He plays a role in thermal insulation and depreciation.

Each of these layers needs certain nutrients for optimal functioning.

1.2 Factors affecting the condition of the skin

The condition of the skin is subject to the influence of many factors, both internal and external. The internal factors include:

Genetics: Heredity determines the type of skin, a tendency to certain problems and the rate of aging.
Hormonal background: Hormonal changes, especially during puberty, pregnancy and menopause, can cause rashes, a change in pigmentation and other problems.
Age: With age, the production of collagen and elastin decreases, the skin becomes thinner, dry and less elastic.
Diseases: Some diseases, such as eczema, psoriasis, diabetes and autoimmune diseases, can appear on the skin.

External factors include:

Ultraviolet radiation: The main factor of skin aging, causing the formation of free radicals, the destruction of collagen and elastin, and an increase in the risk of skin cancer.
Environmental pollution: Contaminated air contains toxins and free radicals that damage the skin and accelerate its aging.
Smoking: Nicotine and other substances contained in tobacco smoke narrow the blood vessels, worsening blood supply to the skin and slowing its restoration.
Inal meals: The lack of vitamins, minerals and other nutrients can negatively affect the condition of the skin.

Incorrect care: The use of aggressive washing tools, insufficient moisture and lack of sun protection can damage the skin.

1.3 Role of nutrition in skin health

Proper nutrition is the basis of the health of the skin. A full -fledged diet, rich in vitamins, minerals, antioxidants and healthy fats, helps maintain its health and beauty. Key nutrients for the skin include:

Vitamin A: It is necessary for the growth and renewal of skin cells. Vitamin A deficiency can lead to dryness and peeling of the skin.
Vitamin C: A powerful antioxidant that protects the skin from damage to free radicals. It is necessary for the synthesis of collagen.
Vitamin E: Another important antioxidant that protects the skin from ultraviolet radiation and other harmful factors.
