Non-insulated microneedle fractional radiofrequency for the treatment of scars and photoaging.

Editor First described by Manstein and Anderson, fractional techniques have revolutionized the management of numerous dermatological conditions, leading to the development of fractional lasers and fractional radiofrequency devices. A retrospective study was carried out on consecutive patients treated with a non-insulated microneedle fractional radiofrequency (NIMFRF) device: Secret (Ilooda, 2 Korea). All patients paid for their treatments. Inclusion criterion was indication for thermal remodelling. Exclusion criteria were recent scars (<3 months), keloid, pregnancy or breast-feeding, refusal of a post-treatment assessment. Treatment parameters were as follows: energy 60% (6.82 Watt), depth set as a function of the dermal thickness (between 1 and 2.5 mm), pulse duration (ms): 100 times the depth (mm), needle penetration duration: twice the duration of the pulse. Anaesthetic cream (Anesderm; Pierre Fabre 3 , France) was applied before the session. Antiseptic treatment was performed just before the session. Patients were treated with 50% overlapping in two consecutive passes. Five passes were carried out on microrelief zones. Cicabio (Bioderma 4 , France) was applied immediately after the treatment and prescribed. No other treatment – especially antiviral or antibacterial – was prescribed. Tolerance was assessed using a 10-point pain score, measurement of the most frequent subsequent effects and screening for
