The time when you can wash your face after laser blemish removal varies somewhat depending on the laser blemish removal method and the degree of wound recovery. If there is no damage to the skin mucosa, washing your face will basically not affect it. If there is an incision, try to wash your face after the scab has completely fallen off, which usually takes 3-7 days. If there may be some damage to the skin mucosa during the treatment, you should not wash your face for a short period of time either. You should probably wait until there is no obvious breakage, oozing, redness or inflammation on the skin surface before you can wash your face, which usually takes more than 1-2 weeks. If patients are not sure whether and to what extent their skin will be harmed by laser blemish removal, it is recommended to ask the doctor about it. However, if the wound has not yet recovered, there may be bacteria in the tap water or the bacteria on the face may be brought to the wound when washing the face, leading to infection; if the force is stronger when washing the face, it will also lead to increased local damage, which will cause increased inflammation and may lead to increased pigmentation after laser blemish removal. In addition, patients need to pay attention to not to use stimulating facial cleanser when washing the face, and try to use water to wash the face in the early stage, not to stay up late during the recovery period, not to eat spicy and stimulating and too greasy food, and to supplement vitamin C in the daily life to help melanin metabolism, and to do a good job of sun protection when going out.
