@gabby333 unders go under the muscle, overs are over the muscle – if you don’t have a lot of breast tissue they prefer to do unders to cover the implant and prevent rippling. If you have enough breast tissue to do the implant then they will do it over the muscle as its less painful and less recovery time x
I had mine yesterday unders because of lack of breast tissue also they have a more natural look, bit i wont low to you. Mt first day for excruciating and they kept mw in bit in home now feeling alot better second day, so worth the pain. Xx
