OBJECTIVE: To explore the clinical effect and safety of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) combined with 1550 nm fractional laser therapy in the treatment of rosacea.
METHODS: 114 patients with type I and type II rosacea treated in our hospital from March 2018 to April 2020 were recruited. They were randomly assigned (1 : 1 : 1) to receive ALA-PDT (photodynamic group), 1550 nm fractional laser (laser group), or ALA-PDT and 1550 nm fractional laser therapy (combination group). Outcome measures included skin lesion scores, efficacy, and adverse reactions.
RESULTS: After treatment, patients in the three groups showed lower skin lesion scores than before treatment, and the combination group showed significantly lower results than the other groups (P < 0.05). There was no significant difference in the total efficacy among the three groups (P > 0.05), but the combination group outperformed the other groups in the comparison of the efficacy levels (P < 0.05). Edema with lupus erythematosus, pain, and burning sensation was found in some cases but disappeared within 2 to 4 days after symptomatic treatment without interference with subsequent treatment. No patients had pigmentation, hypopigmentation, scars, or other serious adverse reactions.
CONCLUSION: In the treatment of rosacea, ALA-PDT combined with a 1550 nm fractional laser can reduce redness and facilitate skin remodeling, with high efficacy and safety, so it is worthy of clinical promotion and application.
