High‐frequency ultrasound evaluation of cellulite treated with the 1064 nm Nd:YAG laser

Abstract

Objectives: To investigate non‐invasive laser treatment for cellulite using the 1064 nm Nd:YAG laser and to correlate clinical results with high‐frequency skin ultrasound images. Methods: Twelve individuals of normal weight were treated on either the left or right posterior side of the thigh with the following parameters: fluence 30 J/cm, 18 mm spot size and dynamic cooling device pulse duration of 30 ms. Three treatments were performed at intervals of 3–4 weeks, and followed‐up 1 and 3 months after the last session. Photographs and ultrasound imaging were assessed before each session. Results: The 1064 nm Nd:YAG laser resulted in a tightening of the skin and an improvement in cellulite. No side effects were reported. High‐resolution ultrasound imaging showed a significant improvement in dermis density and a reduction of dermis thickness. The method is described in detail in Appendix 1. Conclusion: Infra‐red lasers may constitute a safe and effective treatment for cellulite and high‐frequency ultrasound imaging provides a quantitative and objective measurement of the treatment efficacy.
