Abstract:
Objective:To evaluate the clinical effectiveness and safety of fractional microneedle radiofrequency (RF), subsequently followed by narrowband intense pulsed light (IPL), in the treatment of facial photoaging.Methods:A retrospective analysis was performed on 50 female patients who underwent facial photodamage treatment at the Fifth People＇s Hospital of Suzhou from January to December 2021, with an average age of (40±8) years. Each patient received fractional microneedle RF therapy, subsequently followed by two sessions of narrowband IPL therapy at 500-600 nm, with a 4-week interval between treatments. Before and 4 weeks after the final treatment, skin parameters including wrinkles, redness, and sunspots were quantitatively assessed using the Visia skin image analyzer. Patients self-reported their satisfaction levels, and any adverse reactions were recorded.Results:All patients completed the prescribed treatment regimen. Post-treatment evaluations revealed marked improvements in facial skin, characterized by reduced wrinkles, enhanced skin smoothness, tighter contours, and lighter pigmentation spots. Specifically, the pre-treatment scores for wrinkles, sunspots, and redness were (25.6±10.2), (312.6±75.9), and (162.0±68.6) scores, respectively, which significantly decreased to (18.3±7.4), (261.2±82.7), and (129.7±60.1) scores four weeks post-treatment (all P<0.001). The patients＇ satisfaction levels were (6.6±1.2) scores. During treatment, all patients experienced mild erythema and edema, which resolved within 3-4 days. No serious adverse reactions, such as blistering, hyperpigmentation, or scarring, were observed. Conclusions:Fractional microneedle RF therapy, followed by narrowband IPL therapy, emerges as an effective and safe treatment option for facial photodamage, with minimal adverse reactions.
