The redness of the face after acne removal may be caused by ruptured blood vessels bleeding from needle puncture or post-inflammatory hyperpigmentation, and the exact recovery time varies from person to person. If the patient is bleeding from capillaries, the redness usually resolves after scabbing. However, if it is due to post-inflammatory hyperpigmentation, most patients can recover in about a month, but the recovery time for people with sensitive skin is relatively long, taking three months or even about six months. It is recommended that patients do a good job of sun protection after the formation of red marks, ensure that the hands are clean and hygienic, and make the red marks fade as soon as possible by applying cold compresses, topical epidermal growth factors and medical anti-inflammatory masks.
