Will indents heal on their own? I am big into working out. Will chest exercises help improve the indents? (Photo)

Irregular results in my over the internet opinion can ONLY be addressee by fat grafting... Best to use a boarded Plastic Surgeon this time around! 

It's still early in your recovery from gynecomastia surgery. As you heal, the area may feel “lumpy” and irregular. This, too, decreases with time, and massaging these areas will help soften the scar tissue. The #compression garment helps reduce the swelling, and the longer it is worn, the more quickly you will #heal. It can also assist in the retraction of the skin. In the future, if you are still experiencing your crater concern, its best to ask questions of your surgeon or their nursing staff.  They may possibly be able to address the issue with fat grafting or cosmetic fillers if you are a good fit.

I hate to be the bearer of bad news but I don't think it will completely smooth out. It looks like just the dense central breast tissue was removed. That is why liposuction is added - to help contour the rest of the chest tissue. I agree though that it is far to early to tell the final result. I generally think that the final result is seen 3-4 months after surgery. Discuss your concerns with your surgeon. Good luck.
