How it works: This new vacuum-assisted laser gives off a larger-than-normal beam of light that enables a greater depth of penetration and allows for much faster treatment times. An entire back or two legs can be done in 15 minutes. Impressive, right?

Average cost: $450 per session. However, laser hair removal treats hair that is an active growth phase; because all the hairs aren’t in that phase at the same time, between four to eight treatments may be required.
