Yellow scab above tummy tuck incision, does the color look normal? (Photos)

Yes, this happens often since the tummy tuck incision is a big incision. Just keep the area clean and dry and as always, look out for any signs of infection, including foul odor, redness, tenderness, fever, and/or drainage. If you are still worried, best to call your operating surgeon so you can be seen and properly evaluated in person. 

Thanks for your inquiry and excellent pictures, scab came off a small wound. These small areas are common and generally heal well, discuss your concern with your plastic surgeon, good luck. 

Thank you for sharing your question and photographs. It appears that you have a small separation of your incision line that should heal well with conservative management.  It will take a few weeks but inform your surgeon, they will offer you the best advice.  Hope this helps.
