There are many reasons for damage to the "protective layer" of the skin. On the one hand, genetic, pharmaceutical, and some skin diseases can cause the skin barrier function to be weak. In addition, some physical and chemical factors can also damage the skin's barrier function such as cold, dry environment, and day. Sunburn, repeated rubbing and exfoliation, often wash your face with hot water, excessive cleansing, excessive exfoliation, etc.
Wu Yan (Associate Professor), Department of Dermatology, Peking University First Hospital, explains the knowledge of allergies:
Occasionally, our skin may experience redness, itching or stinging after exposure to physical and chemical substances. There are two possible causes for this: one is that the skin is allergic to the substance; the other is the skin. Skin intolerance caused by barrier dysfunction is what everyone usually calls sensitive skin.
Skin allergies may be more familiar to everyone, is an excessive immune response to certain ingredients, once you know that you are allergic to something, you need to avoid contact for life, otherwise the allergic reaction will be more serious than once.
Sensitive skin is less familiar to everyone, but in fact this phenomenon is more common in everyday life, especially when the weather is dry in winter and spring in the north. The main reason for this is that the natural protective layer of our skin is destroyed. The stratum corneum on our skin surface is this important protective layer, medically known as the skin barrier. It can prevent the loss of water and electrolytes in the body while preventing harmful or unwanted substances from invading. This is necessary for us to live in such a dry, micro-organized environment. Once the barrier function of the skin is destroyed, the tolerance or defensiveness of the skin will decrease, and it will show intolerance to various physical or chemical factors. For example, some people feel that the wind, the sun, the ambient temperature are too cold and overheated. The skin will be red and stinging; some people may feel stinging or even rash even if they suddenly use the product that was not used before. These manifestations suggest impaired skin barrier function.

Sunburn, repeated rubbing and exfoliation, often wash your face with hot water, excessive cleansing, excessive exfoliation, etc. Therefore, those who have already experienced sensitive performance need to carefully compare these reasons and help protect their natural barriers in daily care.
If the skin feels uncomfortable after using the skin care products, it is best to stop the product and go to the dermatology clinic of the hospital. The doctor will help you analyze whether the skin is sensitive to allergies or skin barrier function. There are now very convenient and concise testing methods such as patch test, lactic acid irritation test and various skin non-invasive tests.
Just as we usually emphasize active exercise to improve the body's immunity to prevent colds, if we usually pay attention to protect our skin barrier function, our skin will become stronger and more sensitive to external stimuli. .
