Just released today, the newest at home laser from Tria. The digital display now has a counter so the number of pulses can be tracked with each treatment. It also boasts faster treatment times, a longer battery life and FDA clearance for use on the body and face. They say it can be used on women's facial hair- from the cheekline down.
Like the previous model, it's still cordless, has five settings and a built-in skin tone sensor, but sells for $449 (buy direct). I'll soon be posting a profile piece on the 4X, so stay tuned.
