Will a Filler or Belpharoplasty Fix my Under Eye Bags?

An examination by board certified plastic surgeon would be required for the best answer. That being said from your description and photos it would appear that you might be a typical patient for a lower lid blepharoplasty that redistributes your fat rather than simply removing it to prevent hollowing.

Your picture is hard to evaluate.  You need to make sure you do not have any medical conditions leading to such a sudden onset of lower lid bags.  See you PCP and resolve any medical problems before seeing a plastic surgeon.

There are many causes of eye bags. Some are shadow issues, some are discoloration issues. On the realm of this problem, from your photos, it appears you are on the mild end of the spectrum. I would start conservative (filler or fat transfer) and then if you are unhappy the ideal and most effective treatment for this is fat transposition. Make sure you see a surgeon who specializes in this though it is not a simple procedure. Below are some of the common causes of this problem with the treatment that varies depending on the cause. 

1. Prolapsed orbital fat through the orbital septum: treated with lower lid blepharoplasty and fat transpositioning. Can also be helped with fillers or auto fat transfer to the face but the ideal treatment in my hands is surgery for this issue.

2. Eczema: much more common in young people with fair skin. The treatment for this is to hold off on makeup and any manipulation of the lower lid for a few weeks and try some topical anti inflammatory creams. If you have allergies those should be treated also.  A dermatologist is the best person to see for this. We have a multidisciplinary clinic with myself, a plastic surgeon, and my partner, a dermatologist which I think is ideal!

3. Fluid accumulation and/or redundant skin. Could be possible in young patients but would need a good facial analysis and exam to determine. A low salt diet (< 1000mg/day) and a warm compress can help.  I would consider treating with filler/fat transfer, lower lid fractional ablative laser and/or lower lid blepharoplasty.

4. Descent of midface cheek pad. This then causes the nasojugular ligament to become more prominent creating a demarcation and separation of the eye from the cheek subunit. Treated with mid face lift and/or fat transfer.

It is all about the balance of this transition from the orbit to the cheek. There are many ways to treat this and they vary by the underlying cause. I recommend seeing a surgeon who also does a lot of these treatments. This can make a big difference as most people have a combination of the above that lead to the issue.

Hope this helps.

Best of luck,
