Larger eye bag under one eye. What are my options? (Photo)

I always think it best to start with the least invasive approach so my suggestion would be to try a bit of HA filler in the tear trough area. Schedule a consultation with a board certified plastic surgeon in your area to discuss.

The fat around the globe of the eye herniates and causes these bulges.  For young patients, a transconjunctival approach removes the fat without any visible scars.  This should eliminate these bulges permanently. 

Thank you for the question. A simple, quick treatment for the bag is injecting one of several fillers on the market underneath the bag to blend it into the cheek. This usually works well for small bags and can last up to a year. For a more permanent treatment, blepharoplasty is the surgical procedure to remove the fat. Recovery will take about 2 weeks. See an oculoplastic surgeon for evaluation and guidance. Good luck. 

Surgery (blepharoplasty) can help to remove the bulging fatty tissue from your eyelids.  It is important to make sure that you do not have a thyroid condition that may contribute to the problem.  Schedule a consultation with a board certified oculoplastic surgeon to discuss your concerns.  Good luck!

The tear trough you have can be treated with a filler. The filler can be either an off the shelf one or your own fat. The commercial filler I prefer is Juvederm Voluma which is heavy enough to elevate the tissues in the area and hold them. It also lasts about 2 years. Fat, however, once incorporated into the tissue is permanent. It does, though, take about 2 sessions to achieve the desired result. At your age, besides being less expensive over time, another advantage is that it can improve the skin in the area. Basic skin care for someone like you is a cleanser with an alpha hydroxyl, a pH balancer and antioxidant like Vitamin-C Serum and a good zinc oxide sunblock daily. If you still have problems, you can add other products for the specific problem.
