Why is my Tummy Tuck after 2 weeks turning black? Is this normal? (photos)

Thank you for your pictures. It appears that you have to start to have some skin lost above your incision. This is due to reduction in circulation in those areas.  These areas need debridement. 

This could just be hematoma under the skin, but could also represent some skin and fat necrosis. I would recommend that you continue to follow up with your surgeon on a regular basis.
