You may benefit from lower eyelid retraction surgery with possible other concurrent procedures. Need more detailed evalution to determine. See an expert.

Canthoplasty is a procedure that can address negative canthal tilts and improve the appearance of the eyes by adjusting the outer corners, which could give a more almond-shaped appearance. Since you’re healthy and young, you could be a good candidate for this surgery, but there are several factors to consider:
Natural Anatomy: Since your negative canthal tilt and scleral show are part of your natural anatomy, the surgeon would need to assess how much correction can realistically be achieved without disrupting the natural function of your eyelids. They’ll evaluate whether canthoplasty alone would be sufficient or if a combination of procedures might give you the best results.
Age and Skin Elasticity: At 20, you likely have good skin elasticity, which is beneficial for healing and achieving a natural result. However, every individual’s anatomy and healing process is different, so it’s important to have realistic expectations about how much change can be achieved.
Risks and Recovery: Like any surgery, canthoplasty comes with some risks, including scarring, asymmetry, or eyelid function issues. It's important to discuss these with your surgeon and make sure you're comfortable with the potential outcomes.
A consultation with a skilled oculoplastic or facial plastic surgeon would be the best way to determine if canthoplasty can meet your goals. They can provide a more personalized assessment based on your anatomy and desired look.

I would agree that you have a good deal of negative canthal tilt and scleral show and it would certainly be reasonable to have it corrected. Because of the genetic nature of your lateral canthal insertion it would need a formal canthoplasty to reposition that. Just be sure you see plastic surgeons with significant experience in that procedure, best of luck
