Two stage lift and implant revision - is the original incision from the lift opened or is a new one made?

Hello, If a breast implant revision with lift is done in two stages, how is the implant placed in stage two? Is one of the incisions from the lift reopened, or is a new incision made? If the lift incision is reopened when it's only 3-6 months healed would that cause it to look much worse? Thank you
