Is this a double bubble? (Photo)

Dear ochiexx,
based on your photos, it looks like there is minor double bubble. Though rare, some women who undergo breast augmentation will develop a minor deformity known as a “double bubble,” in which additional folds appear underneath the breasts due to the implant accidentally shifting or contracting post-surgery. In most cases, the implant simply slipped too far down the chest wall and traveled behind the breast inframammary crease (the area where the lower breast meets the chest), instead of moving forward to fill the breast cavity. If left untreated, the lopsided implant will form unnatural indentations, resulting in an odd “four-breast effect” rather than the full, rounded chest the patient initially desired.

It is common for implants to move naturally with you when laying down or shifting positions. Asymmetry to some degree is common. Asymmetry that was present before your augmentation will be present after surgery but may be more noticeable now that more volume is added. If a double bubble is present the only way to correct it is through surgery.
