Lower blepharoplasty 3 weeks ago and i can still see the scars? (Photo)

Visible incisions at this point are not uncommon. You should have a followup visit coming up soon. You should ask your eyelid surgeon if your healing is consistent with what they typically see. However, seeing the incisions at three weeks is not at all unusual. I hope this information is helpful.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

Scars and healing from lower blepharoplasty need several months to ultimately heal.  It is not unusual that you might still be able to see the incision lines 3 weeks after surgery.  It is also not unusual to have some tightness and numbness to the area, but these issues should be improving over time and not getting worse.  If you feel that the issues are not improving over time, you should contact your surgeon to be evaluated.  

Viewing your photo, I  do not see the
incisions marks... though 3 weeks out it is possible to still see incisions but
you should be having a follow up with your Doctor to discuss the issue.
