In acne, there are a large number of facial veins on the face, which receive venous blood from the soft tissue in front of the face and communicate with the intracranial cavernous sinus through the inner canthus vein and eye vein. Therefore, if the face, especially the triangular area surrounded by the nasal root and the two corners, is squeezed improperly, bacteria can easily enter the skull through the above channels, leading to intracranial infection. Thoroughly clean: If you want to make up, you must remove makeup first, and then wash your face. Choose weak acid cleaning when washing your face, basically twice a day. After washing your face, you can wipe it with astringent lotion or clear soft water, and clean it with exfoliating mask once a week. Cautious massage: sebaceous glands secrete oily skin, so as to prevent massage, so as not to stimulate oil secretion, and it is easier to get acne. Choose products made of pure Chinese medicines and packaged at one time. Skin care products will penetrate into blood vessels after application, so choose real small packaging products that do not contain any chemicals.
