Is Ultracel the same as Ulthera, just with a new branding? Despite claims to the contrary, these treatments to seem to cause some facial fat/ volume loss?

I’m guessing you’re referring to Ultherapy here. Ultherapy and Ultracel are two different brands of High Intensity Focused Ultrasound treatment (HIFU). Ultracel is often recommended for reducing fatty jowls or bingo wings, so yes it can cause fat loss and often is deliberately used to do this. Ultherapy shouldn’t cause fat loss in the face – as long as the practitioner using it is well trained and is firing the bursts of energy at the right depth into the skin – but over the years I have heard a huge number of complaints from people who feel they have had fat loss following the treatment which are impossible to ignore.
