Would tear trough filler or lower blepharoplasty be best for my eyes? (photo)

Thank you for posting your question here!My answer will be based on the limited information and pictures provided, for a detailed and bespoke plan I would recommend consulting with your plastic surgeon.
Blepharoplasty addresses prominent tear trough ligament and herniated fat or redundant skin , while filler usually addresses hollowness. In your case you don't seem to have either. both options can have unintended consequences or potential complications and little benefit in your case. If you have concerns about the skin quality etc or you want to be proactive I would encourage you to go for much less invasive options like a good skin care routine or lasers etc.I hope this helps, best of luck!

Looking at your photos, I don't see any need for a surgical intervention. Dermal fillers under the eyes can have unwanted side effects such as visible lumps, prolonged swelling and discoloration. I like to use PRP based treatments. The AutoCorre under eye treatment uses a gel created with your own plasma with embedded platelet growth factors to naturally rejuvenate the skin collagen and fat pads in this area. The other alternative is an autologous fat transfer.
