Will rosacea get worse if a person suffering of it gets a HIFU treatment?

HI there! 
We don't find Ultherapy to cause any problem with rosacea or with people prone to hyperpigmentation. These tend to be more superficial and Ultherapy treats deeper tissue. These are just some of the numerous benefits of Ultherapy! No concerns with these conditions or with sun exposure or darker skin types, also no downtime! Feel free to come in for a complementary consultation! 
Best,

No formal studies on HIFU and rosacea, however using logic, HIFU treats under your skin, unlike lasers that treat the surface layer. So it would be very unlikely Ultherapy will flare up rosacea. All the best The Fiori Institute. Brisbane.Australia.
