Thermage or Ulthera for Crows Feet?

While Botox is the gold standard, some of the wrinkles along the crows feet is due to loss of volume and diminished skin and muscle elasticity. Judicious placement of hyaluronic acid filler can help to replenish volume within and near the orbits. In my clinical opinion, Ultherapy is more consistent than Thermage overall, particularly in the case of periorbital areas due to precise nature of Ultrasonic energy delivery where the subcutaneous tissues are visualized real-time with Ultherapy as well as more potent skin retraction and stimulation of collagen with Ultherapy vs. radiofrequency technology associated with Thermage.

There isn't a definitive answer to your question, but it might be helpful to describe the similarities and differences between Ultherapy and Thermage. Both apply heat into the tissues under the skin to stimulate collagen remodelling, which causes tightening over a period of a few months. Thermage uses radiofrequency which is sort of like an electric current. Ulthera uses microfocused ultrasound, so it is applied with precision at specific depths under the surface. For crow's feet, a neuromodulator such as Botox is usually neeeded too because it is the muscle contraction that produces the crow's feet, not skin laxity.
