Why does skin need special care in summer?

How nice to feel the rays of the warm summer sun on your skin after a long, cold winter. However, doctors are not tired of repeating the dangers of ultraviolet radiation. Excessive addiction to tanning turns into peeling, burns, the appearance of age spots. And this is only a small part of the problems that ultraviolet can cause. How to protect the skin from the sun and prevent negative effects?

Sun rays: benefit or harm
Until the beginning of the 20th century, aristocratic pallor was in fashion. People from higher circles of society carefully covered their bodies and faces from the sun. The concept of beauty involuntarily changed Coco Chanel. Her skin accidentally tanned. Society took the tan as a new fashion trend. Since then, the stereotype has been firmly rooted: if a person is tanned, then he is successful and rich, because he can spend his free time on the beach.

In modern society, everything that is useful has become fashionable. Therefore, many questions arose. How does the sun affect the skin? Is this useful? What will happen if you completely abandon the ultraviolet?

Skin Benefits
The sun’s rays trigger a number of important processes in the human body. Among them:

The production of vitamin D. It strengthens the immune system, gives strength to bones. Vitamin improves the body’s absorption of calcium and phosphorus, improves muscle tissue, promotes the regeneration (healing) of the skin.
Mood improvement. Ultraviolet activates the synthesis of the hormone serotonin. It is called the hormone of joy. It normalizes the emotional state, prevents the development of depression, eliminates chronic fatigue, and improves mood.
The treatment of certain diseases. The sun’s rays stimulate the circulatory, nervous, and respiratory systems. They activate metabolic processes. Therefore, sunbathing is actively used to treat various diseases (psoriasis, eczema, tuberculosis).

When the sun becomes harmful
Sometimes the effect of the sun on the skin turns into the development of unpleasant consequences. Most often, such complications are caused by abuse of ultraviolet rays.

The thirst for a dark tan is fraught with such problems:

Premature aging. Sun rays damage the elastin and collagen in the skin. Without these components, the epidermis loses its elasticity, becomes flabby, and wrinkles appear on the face.
Pigmentation. The appearance of unaesthetic brown spots, a scattering of freckles – all these are manifestations of excessive exposure to ultraviolet radiation.
Oncological diseases. Ultraviolet (namely B-rays) can provoke the development of cancer (melanoma, carcinoma). The activity of such rays is observed in the period from 11 to 16, so doctors recommend giving up tanning at this time.
Radioactivity. The most dangerous for humans are C-rays. It is they who carry radiation and can cause serious consequences. But these rays do not reach the surface of the earth. They are destroyed by the ozone layer. In those areas of the globe over which ozone holes are discovered (Australia, New Zealand), the sun is very dangerous.
What happens to the skin
Under the sun, the skin begins to change. And not always for the better. What will be the effect of the sun on the skin depends on the condition and type of epidermis.

It is necessary to sunbathe in moderation
The following picture is usually observed:

Normal skin type. Ultraviolet radiation leads to increased dryness of the cover. Collagen breakdown and water imbalance activate the aging process.
Dry type. The sun’s rays exacerbate dryness. The epidermis dries up, begins to peel off. Redness and irritation appear on the face.
Fatty type. The main problem of such skin is the active work of the sebaceous glands. Under the influence of ultraviolet radiation their productivity increases. Sebum, mixed with dust from the environment, clogs pores and provokes the development of acne, inflammation. In addition, this greasy-dirty layer creates ideal conditions for the reproduction of bacteria, which only increase the formation of acne.
Combined type. This is a common type and the most difficult to care for. On the face there are areas of oily skin (forehead, nose, chin area) and normal or dry. The rays of the sun affect these areas in different ways, so the protection should be different.
The sun’s rays can dry out acne, and sometimes completely eliminate acne. UV exposure depends on hormonal status and proper skin care.
Summer skin care: recommendations of cosmetologists
In winter, the skin suffers from frost, strong winds, sudden temperature changes. Cosmetics for care should compensate for all these negative effects. In summer, the epidermis is affected by sun, heat, and sometimes high humidity. Therefore, “winter” funds should be replaced by “summer”. How to care for the skin in the summer so that it continues to delight with its beauty?

Cleansing
Skin health is directly dependent on its purity. Therefore, do not ignore the cleansing procedure. Otherwise, acne, inflammation, irritation may appear on the face.
