■ The catch — co-equal billing, always
It has no cooling. Every rival diode laser now includes contact or ice cooling — the Tria doesn't, so it stings more, and its small treatment tip makes whole-body sessions slow. It works on light-to-medium skin with dark hair only.
Dealbreaker? Runner-up №1 (DermRays V8S) adds the contact cooling and wide window this lacks ↓

'Laser' is a marketing word
Most devices sold as 'laser hair removal' — Braun, Ulike, Philips Lumea, Nood — are broad-spectrum IPL, not a single-wavelength diode laser. Genuine lasers (Tria, DermRays, CurrentBody) run $300–600 vs $169–320 for IPL; verify the light source before you pay the laser premium.
Wrong wavelength for your skin
Standard 810nm lasers and all IPL are unsafe on very dark (Fitzpatrick VI) skin and do nothing for blonde, red, gray or white hair. Only a 1064nm diode safely treats melanated skin.
Reduction, not removal
At-home laser delivers 75–99% hair reduction over a full course, not permanent removal — maintenance passes never stop, and manufacturer percentages come from short, brand-funded tests. Treat the numbers with caution.
