Dark spots, hyperpignentation in stomach, 6 weeks post liposuction. is this permanent? will it go away, :( thank you (photo)

I had lipo done on december 3. small quantity of fat removed since I just wanted to sculpt my abdomen. Now I have red-like stains were bruises used to be, if I make pressure with my finger they go away. I also see like some veins darkened. My surgen says its rare that this happened, that he's only seen this result once before in 15 years. I will be going to a dermatologist soon, but I would like to know if this stains will go away or if they are definetly permanent. Help, Thank you.
