Abstract:
Objective:To evaluate the efficacy and safety of radiofrequency introduction of L-vitamin C in patients with melasma.Methods:From March to June 2019, 20 patients with melasma were admitted to the Department of Dermatology, the Seventh Medical Center of PLA General Hospital, including 19 females and 1 male, aged 30-60 years, with an average age of 43.5 years. All patients were treated with 22 percent of L-vitamin C once a week, a total of 8 times of treatment and followed up for 12 weeks. Each subject was assessed with standardized clinical photo, skin tests (VISIA skin image analyzer and CK multifunctional skin tester) and patient self-assessment. In addition, the adverse reactions were recorded.Results:Physician evaluation and patient self-evaluation showed that skin symptoms were improved obviously after treatment. 90% of the subjects thought that all of the skin moisture, pores, fine lines, glossiness, and color spots were improved after 12 weeks. The skin texture, ultraviolet stain and the brown spots which were detected with VISIA skin image analyzer were all improved after one week and one month. Difference was statistically significant ( P<0.05). Skin glossiness was significantly improved, skin moisture content increased and melanin decreased, which were detected with CK multifunctional skin tester. The differences were statistically significant ( P<0.05). But there was no significant change in transdermal water loss and red pigment index ( P>0.05). Conclusions:22% L-vitamin C can be used to treat melasma and improve photoaging safely without affecting skin barrier function.
