Give the razor away, keep the blade.

A non-surgical face-lift now arrives as a transaction repeated thousands of times a day across an installed base of more than 35,000 devices: a clinician traces an ultrasound or radiofrequency wand across a jaw, a single-use cartridge counts down its shots, and a cash-paying patient walks out an hour later. That is the energy-based aesthetic-device market — roughly US$6bn today and projected toward US$15bn by 2030 on the broad category measure, though the HIFU/RF skin-tightening slice most relevant here is smaller and slower (nearer US$3.4bn by 2030). Its defining feature is not the machines. It is the consumables they burn. This is a study of how a hardware market quietly became an annuity market, why the firms that missed that turn were punished for it, and what the Korean makers now running the category got right.
