Dent on side of breast. Could this be due to sagging? (Photo)

Good evening,
Yes this looks totally normal for a 7 year old augmentation that has been through the normal wear and tear over the years!

Dear laurenmorris,
I understand your concern. However, without a proper assessment, it would be difficult to determine what went wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

An examination is needed to be sure, but it could be from excess skin. If this is a small area, a fat transfer could be done.

Hi and welcome to our forum!
From your photo, the indentation at the infero-lateral aspect of the breast is apparent, suggesting an adhesion of the soft tissues to underlying muscle or fascia. As I cannot see the breast itself in the photo, I cannot comment on the relationship between a sag (?) and the indentation. A surgical lysis of the adhesion can be performed if the appearance is troubling to you.
Revisit your plastic surgeon for evaluation and discussion.
Best wishes...
