Breast lift scar revision (photos)

I had a breast implant removal along with a mastopexy 10 months ago. One month after the surgery, my dermatologist found that the scars were a little bit swollen, so she told me to put corticoid cream. Now they are flat but wide (up to 1 cm width). I need a scar revision. I think that an excision and suture is the only solution to make them thinner. Are there methods that you would recommend ? Specific stiches ? Dissolvable or regular suture ? Sorry the pictures are upside down.
