The cost largely depends on the brand of HIFU machine that the doctor uses. Ultherapy is the only skin tightening HIFU device that obtained US FDA approval for lifting the neck, chin and brow, and improves lines and wrinkles on the upper chest. The results are also supported by numerous peer reviewed studies globally. Naturally with such strong evidence of its effectiveness, Ultherapy tends to be priced higher than other HIFU machines.
You can expect to pay between S$3,000 and S$5,000 for a treatment.
