You have nicely described about tria. It’s the first home-use hair removal devices which approved by FDA. Actually the truth is Laser Hair Removal is not a permanent solution it is a long term solution, regrowth would be thinner and hair would appear finer. I think for hair removal especially for face better to go in a laser clinic. Because they have good and expensive laser machine. It’s better to talk with a dermatologist before do Laser Hair Removal.
