Top surgery FTM - how can the arm pit fat area be improved? (Photos)

So I have top surgery ftm but the area where the arm pit fat didn't transition down to the chest smoothly. I have started testosterone and have been on it for 6 months now too. I'm 5ft and 130 lbs. Is it possible to liposuction that area to create a smooth chest or am I just stuck with that dent on my chest forever. As my surgeon doesn't want to do anything with it. He suggest to be on testosterone for at least a year to see my body composition from the effects of testosterone. But as I look at it. It is less prominent since I gain weight a little but when I idid loose 10 lbs it just becomes more noticeable. So I gain the weight back to make it less noticeable.
