What a hydrafacial machine actually does
The signature facial is a four-step protocol run through one vacuum handpiece with a spiral tip. A cleansing solution loosens surface debris, a mild acid solution softens the pores, vacuum extraction lifts the contents out, and a hydrating serum is driven in on the last pass. The machine is the pump, the vacuum and the solution bottles; the tip and the serums are the consumables.
Any hydrodermabrasion system can run that protocol. The difference between models is how many other handles sit alongside the vortex tip, how strong and adjustable the vacuum is, and how the solution and waste tanks are arranged. The four systems here cover the range from a compact 7-in-1 for a single treatment room to a 14-handle console that replaces several standalone devices.
