Yeah, price differ by location. Mostly, it should be based on the time the person spends on you, but some places (like the one where I went) have very arbitrary prices. For example, they charge much more for men's upper lips than women's, while it costs them the same amount to do.
What the heck? The face is a much larger area than the rest of the face. Besides, the upper lip IS part of the face.
Look, my whole face and neck were about 370 $ per session, and I was ROBBED. I paid WAY too much. And you're just in the same area.
Get out of there. It's way too expensive.
Also, Lightsheer Duet is a new version of Lightsheer, but the only thing I heard it has improved is pain. It hurts less. The laser place near my home has both. They charge almost twice the price for the Duet, yet the only thing it does is alleviate the pain. Is it worth it? Not for me.
