Ulthera - Are Welts a Normal Side Effect?

Although "welts" can occur after Ultherapy, they generally resolve within several days.  More commonly, patients have described a tenderness and a feeling of relative swelling along the jawline and neck which can last for up to a week after treatment.  The more aggressive the treatment, the more likely this sensation is afterward.

Hi MD, thanks for inquiring about side effects of Ultherapy. It is possible for welts to occur after an Ultherapy treatment, however on the face and neck they typically don't last more than 24 hours. This may vary from patient to patient. When doing an Ultherapy treatment on the deccolletage (chest area) any welting is more likely to last up to 3 weeks. Keep in mind it is very important to choose an experienced and certified Ultherapy provider. 

Welts can happen, especially with the more superficial treatments (1.5 mm and 3.0 mm).  They are temporary, usually lasting < 1-2 days, but can take even several weeks to go away.
