Why does the phenomenon of rough skin appear particularly obvious?

Why does the skin become rough? I am clearly at the age of a flower, but I have skin like an old lady. This feeling is not good no matter how I think about it. Looking at the fair and tender faces of my friends, and then looking at my own rough and dark yellow face, I can't understand why there is such a big difference in life when everything is the same.

Why does rough skin occur?

Lack of water. When the dermis of the skin lacks moisture, the epidermal cells begin to shrink, and problems such as pores and wrinkles become particularly obvious.

Stratum corneum. The base layer of the skin will continuously produce new cells and transport them to the upper layer. After the cells age, they become the outer layer of aging stratum corneum. If the skin is not thoroughly cleaned for a long time, it will affect the skin's metabolism and the shedding of the aging stratum corneum, and the pores will expand.

Skin aging. As we age, the blood circulation in the skin slows down and the fat layer under the skin becomes loose and less elastic. Without proper care, the skin will age faster and the pores will naturally expand.

Excessive grease. Do you often feel that the sebum secretion in the T-zone is particularly strong? When excessive oil accumulates on the surface of the hair follicles, it will cause the pores to swell and become enlarged.

Press on the skin . When caring for your skin, if the method is not appropriate, it will also cause the pores to become larger. Take blackhead removal as an example. If we press the skin hard and casually, it will easily cause the surface layer of the skin to break. Once the dermis is damaged, it will be difficult for the skin to produce new cells, and the pores will also become obvious and enlarged.
