Every year when autumn begins, some people have skin allergies because of dry weather, and now, the annual spring is coming, and for some people, uncomfortable days are coming, and spring will also be allergic due to climate changes.
"Chunmin" is actually an allergic phenomenon of the skin in the spring season, which is the inflammatory reaction of the skin caused by the allergen through the mechanism of allergic reaction. Spring is the season of high incidence of allergies, and this season is also the focus of prevention of "spring sensitivity".
What are the causes of allergies?
Some people think that it is caused by pollen, willow flots, sycamore villi, etc., but many people's spring sensitivity is not caused by these natural factors, but by poor skin care. The main function of the skin is the barrier after hundreds of millions of years of evolution, the outermost layer of the skin is 7-10 layers of dead cells to external mechanical stimulation, microorganisms, light, air, etc. have a certain protection and barrier ability. At the same time, it also blocks most chemical components from entering the skin.
Another important feature of spring is that the hot and cold changes are drastic, and if you are not careful, you may have problems such as colds and decreased immunity.
So what are our wrong skincare methods?
For example, excessive cleansing (makeup removal, facial cleansing, etc.), excessive exfoliation, and another point that everyone is prone to quick success is excessive medical beauty (photoelectric and other items), once these skin care methods are passed, it will lead to damage to the skin barrier and reduce the defense against the outside world.
As a result, cold, heat, wind, dryness, light, microorganisms, etc. may irritate fragile skin and then trigger spring sensitivity.
In addition, we should take more care of our sensitive period, although the spring sun is warm, but the ultraviolet rays are strong, and the irritation and damage to the skin are greatly increased. The temperature fluctuates sharply and cold.
When hot, the capillaries dilate and the rate of skin moisture loss accelerates; In order to maintain blood supply and body temperature during severe cold, blood vessels will also expand compensatively, resulting in red blood streaks.
Be vigilant if you have the following symptoms, such as tight skin, itching, tingling; dry, rough; Predisposition to erythema; It is skin that has a tendency to allergies or has already developed allergic symptoms.
