You can’t prevent rippling as it depends on the thickness of your skin and fat surrounding the implant and muscles if you went under the muscles it can have a slight % less risk maybe I’d say by 20% less chance
Losing weight, as you age, pregnancy all changes your body it’s a risk you take with breast augmentation although majority time those who do have rippling is very mild and can live with it. Some can’t and choose fat transfer or change of implant position
