Cost of beauty treatments, laser hair removal, botox, etc - cheaper in Europe?

I am interested in getting some treatments done while in Europe and am wondering if it is any cheaper than here in the US? Laser pubic hair removal in the US costs on average $2000 and I hear that in Italy it's about 500-600 Euro. Is this true?
I know that SPA treatments in Europe are significantly cheaper in Europe but I am more curious about the long term or permanent treatments. What do you think?
