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

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,

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.  

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.
