A lot of blackheads appear on the nose at once, the essence of which is considered as the following: first, oil; second, shed keratinocytes; third, a large number of microorganisms; fourth, fine hair. These things block the mouth of the hair follicle, forming a small embolism called follicular canal type, the core reason is related to the high secretion of oil, but also with keratinocyte shedding has a close correlation. Keratinocytes are shed from the wall of the follicular canal and form the framework that constitutes the most basic state of blackheads, which contains a large number of particles of oil secretion that provide a good medium for microorganisms to multiply, thus forming a semi-solid state that leads to the blockage of the follicular opening and the formation of blackheads. Therefore, to remove blackheads need to inhibit oil secretion, you can apply a mixture of Adapalene gel and urea vitamin E cream for external use, you can also choose to go to a regular tertiary hospital for medical treatment, such as acid peeling, photorejuvenation, laser treatment, while in the diet need to abstain from spicy, stimulating food, abstain from alcohol, abstain from squeezing blackheads with your hands, reduce the intake of fried and sweet food, keep the skin clean. Pay attention to rest and reduce staying up late.
