The skin doctor pointed out that in fact, this is the dry skin caused by moisture loss in winter, and alternating bathing or exfoliation may cause dry itching of the skin.
It is recommended not to be too diligent in the winter bath, it is best not to repeat exfoliation.
It is easy to make the skin dry and itchy. It is understood that our skin is composed of epidermis, dermis and skin appendages (hair follicles, sweat glands, sebaceous glands).
The stratum corneum of the outermost layer of the epidermis is a barrier to the skin, which not only resists the invasion of foreign bacteria, but also prevents the loss of water from the skin.
Lower temperatures in winter can cause damage to the stratum corneum and damage to the barrier.
At the same time, the sebaceous glands multiply at high temperatures, forming a layer of oil film to prevent moisture loss.
銆€銆€In the low temperature state in winter, on the contrary, sebaceous gland secretion is reduced, and water efflux is promoted.
This is why we have dry skin in winter.
Dry skin, skin surface moisture, pH, etc. change, activate some neurotransmitters, cause skin itching, and also increase the incidence of skin infections.
銆€銆€In addition, some people like to exfoliate the skin, but in fact the stratum corneum is an inevitable result in the skin’s metabolism. Except for some patients with keratotic diseases who need special treatment, other normal people do not have extra exfoliation. In daily cleaning,Can eliminate excess keratin.
The use of some fake, steroid-containing skin care products and masks or long-term external use of steroid hormones will also damage the stratum corneum of the skin and damage the skin barrier.
銆€銆€Skin care products can not hydrate 6 strokes to correct the skin hydrating winter skin itchy, many people will choose moisturizing or hydrating skin care products to ease, and that this can help the skin hydration.
However, skin experts point out that no skin care product can hydrate the skin.
Because the biggest function of the moisturizer is to delay the loss of moisture through the epidermis, and to create a good environment for restoring the barrier function of the stratum corneum, it is impossible for any skin care product to replenish water from the outside of the skin to the skin.

Drink plenty of water and replenish lost water, especially after intense exercise, or stay in an air-conditioned room for a long time, as well as after laser, photon, and radiofrequency cosmetic treatment.
