The Structure of the Skin
The surface of the skin, where it is visible to the naked eye and where cosmetic products are used, is also a collection of dead cells. From this level to the bottom, the multiple functions of the skin take place in 3 thin and various layers made up of different connective tissues and structures. The epidermis is the most important concerning the absorption and the effect of cosmetic products. This outermost layer of skin displays health, cleanliness and appearance while protecting the skin from dehydration, bacterial build-up and penetrating substances. The epidermis gives the skin radiance, suppleness, youth and a well-groomed appearance. As your protective barrier, UV radiation, acne, different diseases and cancer mainly affect this layer.
Normal Skin
Natural skin has a balanced moisture and appropriate elasticity. In this skin, there is biological activity in the basal layer. In such a way that the blood flow is active in it and a balance in its metabolism is observed in general. Normal skin has a uniform and soft appearance, is moist, with a firm structure, and has a unique color and shimmer.
Oily Skin
Oily skin is caused by the overactivity of the sebaceous glands. This activity is controlled by androgen (male hormone). The indicator of oily skin is a firm, thick and shiny appearance. Pores are usually caused by fat trapped in the follicles of the larger fat ducts. These holes are more visible during dehydration. Hot and humid weather increases the secretory activity of sebaceous glands.
Dry Skin
Dry skin is the result of low sebaceous gland activity. Although dry skin is hereditary, it will also be caused by the aging process. At this time, as all the activities of the body decrease, the activity of the sebaceous glands decreases as well. Dry skin tends to lose water more. Since the fat on the surface of the skin acts as a natural barrier against the loss of moisture, the lack of fat reduces the ability of the skin to store water.
Common skin conditions
Dehydration
Dehydration is one of the most common skin conditions. It means a lack of sufficient moisture in the cellular system and intercellular space. Dehydrated skin looks dry and scaly, and the inflexibility of the skin is completely felt. Wrinkles are created when the skin is gently stretched, like when we pull the corner of a tissue. Dry skin and oily skin can both suffer from dehydration. Dry skin is more susceptible to dehydration due to the thin surface layer of the skin to store moisture. Oily skin can lose water when alkaline soaps are used excessively.
Skin redness
It usually occurs as a result of the elasticity and weak resilience of the capillary walls. When the blood flow suddenly increases in a part of the skin due to external stimuli, heat, and mental-emotional factors, the capillaries expand so that more space is available for the blood. When the amount of blood decreases, the capillaries should return to their normal state. If the capillary wall does not have enough elasticity, it does not return to its original shape, and as a result, it keeps the blood cells in its structure and causes redness on the surface of the skin.
