Differential diagnosis
Differential diagnosis of dry skin:
1. Water-deficient dry skin: Some women of this type of skin do not know that they are dry skin, because their sebaceous glands have no problem, but the skin is extremely deficient due to improper care or other reasons. The skin's internal moisture and sebum are out of balance, causing the skin to stimulate the secretion of sebaceous glands to increase, resulting in a "dry inside" situation.
2, lack of oily dry skin: women of this type of skin usually know that they are dry skin, because their sebaceous glands secrete less cortex, the skin is dry because it can not lock the moisture in time, the skin is lack of luster, the outside world The stimulation is more sensitive.
3, dry skin: dry skin refers to the season due to changes in water, anemia and other reasons, making the skin thicker and rougher. In autumn and winter, the sebum and water secretion of the human body will gradually decrease, and the skin will become dry. It is called dry skin. Especially in middle-aged and elderly people, the surface of the skin will appear more rough due to the large amount of water, and they will often see their hands and feet. There will be chapped and itchy skin in the calf. If you can't stand the dry itching, you will continue to scratch itching, causing skin wounds, causing inflammation or pus.
