I love the fact that the Tria 4x laser gives me professional results at home without costing me thousands like it would at a dermatologist's or medical spa! I'm lightskinned Italian with coarse, dark hair so I'd have visible stubble on my legs and armpits after shaving. Now the hair is only growing in a few, thin patches and at a slower rate. The photo shows my lower leg after a month of not shaving. Before lasers, I honestly would've looked like a gorilla!
I use it on the highest setting and it does sting for a quick second, but so long as the shave is close, which is important, it shouldn't feel like a burn or anything. I've heard that some people use numbing creams beforehand with great success, but it's not justified in my case. The instructions that came in the box were very clear and easy to understand. For all purposes, you just use the one button it has on it to adjust the power level and then hold it against the skin to activate a zap. You have to lift it up off the skin and then press it back down to trigger each zap which makes it more time consuming than some of the professional machines, but it's definitely worth the savings cost to me and now I don't have to spend nearly as much time shaving either! I highly recommend this!!!
