Start with the treatments you plan to offer, then compare the specs that decide whether a machine can deliver them. The comparison table above lists these side by side.
Needle depth
Depth sets where a machine can work. Facial treatments usually sit in shallower ranges, while body areas such as stretch marks can call for more. In this collection, the Minas TM50B adjusts from 0.5 to 3 mm, while the TM80 covers 0.2 to 3.5 mm on the face and up to 7 mm on the body.
RF frequency and modes
Frequency and RF mode change how energy is delivered at each depth. The TM80 switches automatically between 2.2 MHz for superficial layers and 700 kHz for deeper dermal work. The TM50B offers monopolar, bipolar and fractional RF. The Shape Tactics Targeted system has 1, 4 and 8 MHz settings.
Cartridges and needle types
Insulated needles concentrate energy near the tip, which helps keep heat below the surface. Non-insulated needles deliver energy along more of the needle. Pin count, from 10-pin tips for detail work to 64-pin tips for larger areas, affects coverage and treatment time. Check which cartridges a machine accepts, what they cost and how easily you can reorder them.
Cooling, vacuum and extras
Cooling handles and cold hammers support client comfort after treatment. Vacuum assist holds the skin against the tip for more consistent contact, and the TM80 uses vacuum sensing to prevent empty shots on uneven contours. Extras like a skin analyzer or blue light add services, but they only add value if you plan to use them.
Match the machine to your practice
- Adding a first RF microneedling service on a tighter budget: the Shape Tactics 3-in-1 Vacuum system, which also includes a cold hammer, skin analyzer and 415 nm blue light.
- Facial work with frequency control: the Shape Tactics 3-in-1 Targeted system, with 1, 4 and 8 MHz settings, vacuum assist and a cold hammer.
- A face-focused menu with several RF modes: the Minas TM50B, with monopolar, bipolar and fractional RF and a dedicated cooling handle.
- Face and body treatments from one platform: the TM80, with up to 7 mm of depth, 13 cartridge types and a 3-year warranty.
