If scattered erythematous papules and erythema appear without pain, then a mixture of fusidic acid cream and mucopolysaccharide polysulfate cream can be applied topically. 2. If a large number of erythema appear with cystic erythematous papules and stinging pain, oral compound glycyrrhetinic acid tablets and vincristine capsules can be taken under the guidance of a dermatologist. Oral doxycycline hydrochloride tablets can also be taken. The actual dermatologist will be able to take the topical medication such as Adapalene gel and Urea Vitamin E cream, combined with blue light treatment. 3, you can choose to go to a regular tertiary hospital for medical aesthetic treatment, such as acid peeling, photorejuvenation laser and gold micro-needle ion introduction treatment.
