Trapezius Slimming (shoulder slimming) uses Botox or Dysport to gently relax an overactive trapezius muscle, helping create a softer shoulder line and the look of a longer, more elegant neck. In Dr. Donald B. Yoo’s Beverly Hills practice, this quick nonsurgical treatment can also ease neck and shoulder tension from chronic overuse, with little to no downtime. Most people resume normal activities right away, notice fuller slimming over about 6–8 weeks, and may maintain results with follow-up treatments as needed.
