After laser, blisters can be applied to the affected area by applying a cold moist decoction of Chinese herbal medicine fresh Amaranthus, Huang Lian, Phellodendron and Scutellaria to clear heat and dry dampness and absorb blisters. If the blister wall is thicker and larger in diameter, a sterile syringe should be used to extract the blister fluid to dry out and absorb the blister. If the blister is rubbed out and shows vesicles and oozing, topical fusidic acid ointment needs to be applied twice a day to prevent infection. If the blisters show purulent exudate, azithromycin tablets should be added orally and a wet application of Revnor solution should be applied twice a day for anti-infection treatment.
