Practitioners starting out usually ask which device is best. The better question is which treatments you intend to sell, because that answers it.
PlasmaPen
The workhorse for soft surgery: upper and lower eyelids, perioral lines, neck laxity and lesion removal. If your treatment list leads with eyes, this is the first device to buy.
CoolJet
Cold plasma, and a genuinely different modality rather than a variation. It works below the threshold for sublimation, which makes it a skin conditioning and product penetration tool rather than a lifting one.
Where it fits commercially
It is the device that fills the gap between facials and soft surgery — lower ticket, no downtime, and it suits clients who are not ready to commit to a lifting treatment.
Fusion
Combines both approaches in one handpiece. For an established clinic already running a full treatment list, it reduces the number of devices on the trolley. For someone starting out it is more capability than the client base will initially ask for.
A reasonable order
Most practitioners do well starting with PlasmaPen, adding CoolJet once the appointment book supports a second treatment tier, and moving to Fusion when bench space rather than capability becomes the constraint.
