The Efficacy of Noninvasive 1060-Nm Diode Lasers for Submental Lipolysis: A Pilot Study

Abstract

Background: Submental fat is a noticeable fat in the submental region that is of great concern aesthetically, especially to female patients. A 1060-nm diode laser is a clinically proven device for the laser lipolysis of subcutaneous fat cells. This study aimed to evaluate the safety and efficacy of a 1060-nm diode laser for submental fat reduction. Methods: Twenty subjects with unwanted localized submental fat were treated with a single session of a 1060-nm diode laser with an energy setting between 0.95 and 1.40 W/cm 2 , depending on each patient's tolerance. Submental fat thickness measurements were documented at baseline, and 1, 3, and 6 months after treatment. Clinical photographs, ultrasound images, and adverse events were evaluated at each follow-up visit. Subjects responded to a satisfaction questionnaire at the end of the study. Results:The subjects had a mean age of 34.55 ± 6.19 years, a mean body weight of 70.66 ± 10.55 kilograms, and most (95%) were women. The average energy setting was 0.95-1.40 W/cm 2 , with a pain score of 3.90 ± 1.30 on a 0-to-10 scale. A significant reduction in submental fat thickness measured by ultrasound was noted at post-treatment month 3 (falling to 0.46 ± 0.13; P = 0.013). However, there was a slight increase in the submental fat thickness at the 6-month follow-up (to 0.48 ± 0.12); the change in the thickness relative to the baseline was nonsignificant (P = 0.121). Most subjects reported an improvement 6 months after the treatment. No severe adverse events were observed throughout the study period. Conclusion:Our study demonstrated the potential role of 1060-nm Diode laser for the treatment of localized submental subcutaneous adiposities. It is a promising alternative treatment modality for patients seeking an in-office, nonsurgical procedure for fat reduction without severe complications.

Aplicación dinámica de un láser de diodo 810/940 nm para reducir grasa abdominal. Estudio preliminar

“…En la técnica de aplicación estática con láser de diodo (1060 nm), el calentamiento global, se produce por la energía total emitida en el área tratada, a través de varios dispositivos, durante 25 minutos, manteniendo la epidermis a 15°C durante el tratamiento por el sistema de enfriamiento empleado [8,14]. Esta modalidad genera un efecto mayor en profundidad y más limitado en la superficie cutánea; afectando más al panículo graso y menos a la superficie cutánea.…”
