Fire needle pretreatment with 5-aminolevulinic acid photodynamic therapy combined with low-dose isotretinoin in the treatment of severe refractory nodulocystic acne
Nodulocystic acne is a severe form of acne, which is commonly treated with oral isotretinoin, hormones, or antibiotics. However, drug therapy often has some side effects and poor compliance. Fire needle combined with 5-aminolevulinic acid photodynamic therapy (ALA-PDT) is a simple, effective, short-term treatment with few adverse reactions, which is expected to be an effective physiotherapy for nodulocystic acne. Moreover, the combination with isotretinoin can reduce the dosage of the drug, thereby reducing the side effects of isotretinoin.
