Removing Scar Below Crease After Breast Augmentation?

Thanks for your question!
Some other options, other than scar cream and silicone sheeting, would be a laser to the area or microneedling. Check with your surgeon for specific recommendations suits for you. Best wishes!

It's reasonable to assume that your inframammary incisions were placed at the same level relative to your nipple areola complexes and breast mounds at the time of surgery. This suggests that your right breast implant has migrated superiorly. This frequently occurs with unilateral capsular contractures.Although this scenario is impossible to confirm without additional history, pictures and a physical examination, your current history suggests this is a strong possibility.Under these circumstances, lowering the breast implant pocket might hide the scar. If the breast implants are properly positioned, simple scar revision still represents a viable alternative.It's important to discuss your situation with your plastic surgeon. Your surgeon should be able to evaluate your scar and formulate a treatment plan that addresses your anatomic findings and achieves your aesthetic goals.

Unfortunately scars can never be made invisible only improved or concealed. IF your breast implants are in symmetric positions there are no ways to practically raise the scar. However, I suspect you implant capsule has contracted causing the scar to appear relatively lower, In this instance a capsulotomy could lower the scar. 

In general, I don't like the crease scar because of positioning issues, occasional hypertrophy, etc.
Since starting to use so many more silicon implants, I have used it more often.
If the implant is where you like it, leave it alone and don't drop it.
Because of what you mention about the implants looking too round for your taste, and the fact that the scar "settled", I believe you had a capsular contracture.
As the capsule contracts, the footprint of the implant on the chest wall decreases, thus the bottom of the implant appears to elevate relative to the scar.
Depending on what you want, you may need a capsular release, or a repositioning of the scar.
I have repositioned crease scars, it is done under a local anesthetic.

It seems that the implant may be too high from where the incision was placed. If that is the case, lowering the device would make the scar less conspicous.
