Will this very white breast augmentation scar by my nipple go away? (photos)

It looks like this scar has reached maturity and will remain pretty much this way. You can ask your surgeon about nonsurgical scar treatments such as laser technologies. Avoid tanning. It will only make it worse. 

The scar around the areola is mature and the expected outcome except at the base of the breast where the scar is wider. Revision is possible on the base of the areola only.  I would not tan!!!

Due to ischemic trauma to the skin there is significant variegation in color. This will not get better but could be improved by a scar revision.

You Underwent a combined procedure with tightening of the skin of your breast.  It appears that there was some delayed wound healing in this area which led to scar tissue.  It appears that the tissue in this area remains tight and may be under some tension at this point still.  Ideally a scar revision would be needed but you must have enough laxity in this area.  Consult a board certified plastic surgeon to discuss treatment options.  Its unlikely that any type of cream will help at this point. 

If this is a scar, it is unlikely this will resolve. Over time it may shrink slightly, but scars present at one year's time will probably not change significantly in appearance. If the skin is not tight, a scar revision can be considered. A more conservative option would be to have someone certified in micropigmentation try to match the scar color with the color of the surrounding skin. I am unaware of any creams that will reduce its appearance. Tanning the surrounding skin may make the scar more obvious as scars don't tan the same.

The scars will likely not change this late in the game. Some consider tattooing the light scars to blend in a bit better.

The spread whitish scarring may be improved by micro needling, tattooing a light color, or even scar revision. You need IN PERSON opinions... 

Since these scars have matured over the period of the last year, there is little change to be expected from this point.  The scars appear soft, pale, and at their endpoint in terms of improvement after surgery.  There are no topical treatments that I am aware of to make them better.  Removing the scar surgically and resuturing the area now that the bloodflow has improved will likely give you a thin, fine scar you would be more pleased with.  Best regards,-Erik Hoy, M.D.

Dear Michelle,Thank you for your post.  You have this scar under your areola because some of the skin in this area partially necrosed.  This scar tissue will not go away because it is not normal skin and thus has no melanocytes that create the pigment in normal skin.  The only way to improve this area is to cut out the scar with a revision.Best wishes, Pablo Prichard, MD

The white scar is caused by deep pigmentation following your surgery.  At this late date it is unlikely to change.  A scar revision certainly is possible and in my opinion will give you a better result than tattooing.
