Are eyelids supposed to be this red 3 months after upper bleph? (Photo)

This can occur from the inflammation of the surgery in patients with fair, thin skin.  It may improve over about 6 months.  It it persists some laser treatments can help, but you need to make sure the eyes are well protected!  If you also have some rosacea, some doxycycline pills may help.  

No, what you are experiencing isn't the norm, but it's not atypical in fair skinned patients such as yourself. Just to err on the side of caution, I would advise you to schedule an appointment with your surgeon just to make sure that nothing else is going on. Otherwise, it will simply take time for your redness to resolve. My best,

Thank you for sharing your concerns and photo. You may have post op inflammation that will require more time to heal or possibly changes in your skin that will require further treatment. See your surgeon for follow up evaluation in a few more months. There is still a chance that the redness will resolve. Good luck.

 Dear mom2gandj Thank you for your questions and photos!  The colour of your eyelid skin can occur with blepharoplasty   although the color may have been present before your surgery. Please review your preoperative photos with the eyelids closed. The color can be treated with laser or intense pulse light  with great care.With warmest regards,Trevor M Born MD

It isn't unusual to have some redness still, especially if you are fair skinned.  Make sure you are extra diligent with sunscreen to prevent redness at scar and also give it a few more months.
