Hey, im having cui implants on the 29th and have been so worried about this, so after doing lots of research online it seems that mostly it depends on the placment ( under or over ) and also how much breast tissue you had before, also if your skin is thin, if you are realy skinny and dont have alot of breast tissue they advise naturelle but if your surgeon has alowed you to have cui then im sure you are fine and wont have any rippling! The surgeons wouldnt let you have cui if they felt you wasnt suitable for them :), so dont panic im sure you will be fine ! 🙂 xx
