Hi ninaxo! I was wondering about the same sort of thing. I am booked in for unders and one of the main reasons going for a BA was that I hate my boobs when I bend over. I was wondering if the implant, muscle and breast tissue separated when tipped forward. Apparently they don’t. In your case this is just one of those things that may happen if your skin doesn’t have much elasticity. But how do you know until you’ve had kids and your boobs have drooped?
If you are young then I wouldn’t worry yourself over it. If you are ancient like me then it might be a question to ask the surgeon when you meet him/her. Personally, I’m not worried about it. Its going to be better than what I have now and I can always have an uplift if they head south.
Anyway, I found these sites helpful:
