My skin is yellow underneath my boob is this normal? (Photos)

The yellow you see is most likely the resolving of normal bruising after surgery. When you are concerned, it is always a good idea to check with your plastic surgeon. Hope this information is reassuring. For more information on this and similar topics, I recommend a plastic surgery Q&A book like "The Scoop On Breasts: A Plastic Surgeon Busts the Myths." 

Hello,Thank you for your question and photo. Yellow is expected as bruising resolves. You appear to be on track.All the best

Thank you for your question.  The yellow discoloration is likely normal bruising that has occurred as a result of your procedure.  Increased swelling, pain or redness should be evaluated.  Best of luck.

Hi there, Thank you for your question. A yellow hue under your breast is normal. A bruise turns yellow as it is healing. Best, realdrsix
