Hi P-chan! The longest controlled study I've seen with these patch devices measured results at nine weeks. Waxing can last that long for some people.
These devices have been around for a very long time in various forms, and there is still no published data indicating they can achieve permanent hair removal (one year after final treatment). It's only "permanent" if you consider nine weeks an acceptable threshold.
Save your money!
