The pores on the back are densely packed with black spots

The pores on the back are densely packed with black spots. This is mainly due to the dense distribution of hair follicles on the back. Long-term sweating stimulation can cause a large amount of sebum to be secreted inside the hair follicles. These excessive sebum cannot be removed in time and blocked in the hair follicle mouth, forming a horny plug. The end close to the skin surface turns black due to oxidation, thus forming the black spots we look dense. At this time, if you touch it with your hand, there will be obvious keratinization, and you can squeeze out black horn plugs and white cortex. Showing dense black spots in the pores on the back, it is related to the patient's strong androgen secretion, sweating, eating spicy and stimulating foods, staying up late for a long time. During treatment, compound lactic acid cream and adapalene gel can be used externally under the guidance of a doctor.
