Skin Wrinkles on Bruised Area After Lower Eyebag Blepharoplasty

I had lower eyebag blepharoplasty 7 weeks ago. Most bruises disappeared 2 weeks after surgery, but some residual bruises remained. My doctor said these too would go away in times. About 1 week ago, the skin area where these residual bruises are became dry, wrinkled and very creased (but other skin areas where the eyebags were but not bruising are ok). The doctor said that's dead skin to come off. But 7 days down the track it's still much the same. I am worried, and I want a 2nd opinion.
