I had full body laser, one thing to keep in mind is that it only reduces hair not permanently removes it so it’s best to get a top up every year/other year, also if you get pregnant it can grow back. For me it was really worth it as I had dark hairs & lots of them & I barely need to shave now (I don’t really care about having thin sparse hairs), plus the package wasn’t super expensive as I went to a chain.
If you get it make sure you only get it done on thick, dark hairs & that the place you’re going to is using good lasers. Alexandrite or ND:Yag under the candela brand are the best I think depending on your skin tone.
