Wash your face with moderation, and be careful that the more you wash, the more oily you become

There are many factors that cause skin sensitivity, including internal factors such as age and endocrine, as well as external factors such as pressure, bad mood, drinking, spicy and stimulating diet. Among them, excessive cleaning is a very common and important cause of skin sensitivity.

The outermost layer of our skin is the stratum corneum, which has a sebum membrane emulsified by sweat and sebum to provide protection for the human body. Excessive cleaning and improper use of cosmetics (such as washing your face with alkaline soap) not only remove the dust, aged horniness, microorganisms, etc. on the skin surface, but also destroy the normal sebum film, which can not achieve the purpose of skin care, but will damage the skin. People with oily skin (such as acne) always want to wash all the oil off their faces, hoping to improve the symptoms of blocked hair follicles and acne. Unexpectedly, this will make the skin more oily. Because the local environment of the skin also has feedback regulation, the sebaceous membrane can inhibit the secretion of sebaceous glands. Excessive cleaning will lose sebum and reduce the pressure of sebum membrane to inhibit the secretion of sebaceous glands. On the contrary, it will accelerate the secretion of sebaceous glands and secrete more oil, resulting in greasy face.

Excessive cleaning will also cause damage to the skin barrier function, increase the speed of skin water loss, water shortage, dryness and roughness; The protective effect is weakened, harmful microorganisms, external chemical, physical and biological factors are easy to invade or stimulate, especially vulnerable to ultraviolet radiation, and feel stinging when using skin cleansing and cosmetics.

For people with sensitive skin, it is recommended to wash their faces with water at 36 ℃ ~ 37 ℃ close to their body temperature to avoid cold and hot skin irritation; Use mild soap free cleansing products; Try not to use exfoliating products, and choose medical skin care products and physical sunscreens that do not contain spices, preservatives and are less irritating; And pay attention to the law of life and relax.
