First of all, there is a certain relationship between skin allergy and the environment. Long term exposure to sunlight or air pollution, smoke, dust, ultraviolet light and infrared rays will damage the skin. That's because the free ions they produce can damage the lipid protective layer of the skin.

Secondly, inferior cosmetics or improper drugs are harmful. There are also physiological factors, such as stress, mental tension and depression, which will weaken the skin's natural resistance and slow down its self repairing function. Such as endocrine disorders. Also can cause skin allergy!

Finally, with the growth of age, the secretion function of the skin will degenerate, and the skin will become thinner with the elapse of years, and its protective layer function will also weaken. In addition, in the face of weather changes, the skin also needs additional adaptation. For example, in cold weather, if the skin is not fully moisturized, it is very vulnerable.
