Does Ultherapy work on brown skin?

Ulthera is an excellent modality for dark skin types and works well on the lower face, jowls, and neck.  Raffy Karamanoukian, Santa Monica

Ultherapy uses ultrasound which stimulates movement in the molecules of the dermis, regardless of color of the epidermis. Unlike laser, color is not the target, so it can be used safely with all skin types. I am however, more cautious with the superficial 1.5 mm. transducer as it can cause some welts but they go away quickly. In skin of color there may be a theoretical risk of a welt causing some post inflammatory hyperpigmentation, although I have not seen this.

Yes, it does work on Asian/brown skin as it does not have anything to do with the pigment in the skin. It's best to get it done from someone that you trust. An important question is to ask the office how long they've had the machine, as this can give you insight to experience.
