What is going on with my periareolar stitches? (Photo)

Almost three weeks post op. I noticed after the bandages came off that each nipple actually seemed to have two lines or scars. I asked my doctor and he said the top line wasn’t my incision it was a technique to make the scar lay flat. At this point the top “line” is becoming like a valley and worse than the incision line. Are the sutures still dissolving or will it stay like this forever?! Help!
