Had upper bleph 6 months ago, and my eyes still look tired and droopy. How can I make my eyes bigger?

Upper blepharoplasty doesn't actually raise the upper eyelids. What actually raises the upper eyelids is ptosis surgery. Need evaluation by an oculoplastic surgeon to determine if you have ptosis and if you would benefit from ptosis surgery.

Now you need a second surgery. It is actually worse than that because upper eyelid ptosis can make the ptosis surgery much more complicated. You still need a combination upper eyelid ptosis surgery and a blepharoplasty. It is very common to be offered a posterior ptosis surgery, called a Muellerectomy. I strongly recommend an anterior levator resection ptosis surgery instead. You have upper eyelid lash ptosis. That suggests that there is a weak connection between the skin and orbiclularis muscle in the upper eyelid and the levator aponeurosis. A detailed preoperative assessment would confirm that. I suggest that you read my reviews to understand what is possible. I am attaching a video on the anchor blepharoplasty. Choose wisely. Your eyes can be your best feature.

Based on the photo, you seem to still have some excess skin. However, you should understand that your surgeon could not remove so much skin as it might cause more harm than good. Too much skin removed would usually cause incomplete eye closure. There is a limit to what blepharoplasty could do. But if you are still unsatisfied with the results, it would be best to consult directly with your surgeon regarding concerns on the result or schedule an appointment with another board-certified plastic surgeon for the second opinion.
