Effect Of Minocycline Hydrochloride Combined With Photodynamic Therapy On Skin Barrier Function Of Patients With Acne

Objective: The aim of this study is to evaluate the effects of minocycline hydrochloride combined with photodynamic therapy on skin barrier function of patients with acne. Methods: Eighty-eight acne patients admitted to our hospital were randomized into research group (n=44, photodynamic therapy on the basis of minocycline hydrochloride) and control group (n=44, minocycline hydrochloride). The clinical efficacy, skin barrier function indexes (transdermal water loss (TEWL), stratum corneum water content, pH value), scores of GAGS and Acne-QOL, cosmetic satisfaction and adverse reaction rates of the two groups were compared. Results: The total effective rate of research group was higher than that of control group (P<0.05). After treatment, TEWL, cuticle water content and pH value were improved compared with those before treatment, and the research group was superior to the control group (all P<0.05). After treatment, the GAGS scores of both groups were lower than those before treatment, and the research group was lower than that of the control group (all P<0.05). The cosmetic satisfaction in the research group was higher than that in the control group (P<0.05). There was no marked difference in the incidence of adverse reactions between the two groups (P>0.05). After treatment, the quality of life scores of patients were higher than before treatment, and the research group was higher than that of the control group (all P<0.05). Conclusion: Minocycline hydrochloride combined with photodynamic therapy can effectively improve the skin barrier function of patients, relieve clinical symptoms, and enhance the overall efficacy and quality of life. It is also safe and patients are highly satisfied with the cosmetic effect.
