Thread lifting gives immediate results but is minimally invasive and will cause some discomfort and swelling immediately after the procedure.
HIFU e.g. Ultherapy is non-invasive and will give gradual lifting results after several months due to deep tightening of the supportive tissues. Immediately after the procedure, some soreness is expected.
Both these treatments are complementary and may be done sequentially separated by a period of time (e.g. several weeks or months) to achieve both immediate and long term results.
The discomfort of doing both procedures on the same day is often too much for a typical patient to bear. Hence, I would not recommend doing both procedures on the same day.
As with all aesthetic treatments, safety is paramount and a progressive approach is recommended than an aggressive approach where side-effects (pain, swelling, bruising, etc) are accentuated.
Hope this helps!
