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.
