Is it normal to get a rash from Ultherapy? When should I expect it to go away?

It is not typical to get a rash from Ulthera. It could be due to dry skin. I have had some patients experience dry skin after the treatment. Try using a rich hydrating cream that is hypoallergenic.

  Dear 2funny, thank you for your question. Ultherapy is the only FDA
approved noninvasive device for lifting the face and neck. It uses focused
ultrasound to target the deep tissues above our muscles, as well as more
superficial layers. Our San Diego clients have been very pleased to see
significant results with no downtime. Side effects are extremely rare but you
should follow up with your provider to express your specific concern.

The rash you are experiencing is most likely from the Ultherapy treatment and it can be treated with a cream to hydrate and reduce the inflammation in the area. Typically, if your skin reacts to the gel used immediately following the Ultherapy treatment, it most likely would be an allergic reaction. However, since you are still experiencing this rash, it may be some type of inflammatory response and you can get it treated by an over the counter cream.

The rash you are experiencing most likely stems form the Ultherapy. For patient's who experience prolonged reactions like yours I recommend seeing the doctor who performed the treatment. He/She will be able to prescribe a topical treatment for the rash. 

It is related to Ultherapy since it occured after the procedure - in medicine we say that it is "temporally related to the procedure" meaning that it is likely to be from the procedure. If it occurs immediately after the procedure it is probably from thermal injury (welts) or reaction to the gel (allergic). But this far out, it is probably some inflammatory response or eczema which should be treated with an over the counter rteroid creme - 1% hydrocortisone - if it does not get better in 2 weeks, seek a dermatology consultation and also see the treating physician. 

Yes, you can experience a variety of minor side effects after Ultherapy, including swelling, redness and / or itching. My wife experienced some annoying, yet minor itching and focal areas of swelling within a few days of Ultherapy and I gave her a few days of prescription low dose oral prednisone which very quickly calmed it down. I recommend seeing your treating physician because I am certain that he or she can provide you with an accurate assessment and recommend some medication to alleviate this problem. Good luck.
