No, not at all. Believe it or not I’ve had my implants for 20 years! It’s only been the last couple of years that they’ve started to sag. But I’ve been quilty of not wearing a sports bra as much as I should. My implants are under my pecs so basically the implant won’t sag but over the year, eventually the breast will. It’s just a fact. But I can’t complain. They’ve looked fantastic for this long 🙂 Are you just at the research stage yourself?
