Pitfalls. Ice and skin: what's the connection?

Pitfalls!

The effect of low temperatures on the skin threatens the development of rosacea. Rosacea has several stages. In the first stage (erythemo-telangiectatic), it may appear only as redness. Over time, small dilated vessels appear (telangiectasias - vascular stars, they are also called "vascular spiders"), along with this, the redness now has a permanent character.

This is what is commonly called couperosis. Cooperosis is the first stage of rosacea.

What is the reason?

Under the influence of low temperatures, the capillaries narrow, and then expand compensatory.

This process occurs every time there is a temperature drop. It leads to the fact that there is a violation in the work of blood vessels. They are unable to respond adequately to temperature factors and expand or contract in a timely manner.

Subcutaneous capillaries gradually expand, fill with blood and "result on the face" - they become visible on the skin.

Of course, the etiology of rosecea is multifactorial and the temperature factor is one of the factors of development. But you should know about him.

Exacerbation of atopic dermatitis, eczema in the area affected by cold

In these two conditions, the barrier functions of the epithelium are disturbed - the permeability of the skin increases.

The cold damages the already damaged epidermis, leads to the narrowing of blood vessels, disrupts the blood supply and nutrition of the skin, which contributes to the appearance of microcracks and irritations.

Cold urticaria

It is characterized by redness, itching, the appearance of papules and blisters at the site of exposure to cold.
