Bags right above my mid cheek / under eye area - Is filler wearing off or is this aging? (photos)

Hello, and thank you for providing photos along with your question. Aging will always influence volume loss in the cheek area and may worsen undereye bags and puffiness. In addition, hyaluronic acid fillers that are commonly used to refresh this area will wear off over time. You will need touch-up treatments to maintain your positive results. The best way to determine the appropriate treatment is to schedule an in-person consultation with a reputable board-certified facial plastic surgeon. Your surgeon can do a proper evaluation, customize the best treatment plan according to your desired goals, and ensure the best possible outcome.

It appears you would benefit from having your filler treatment refreshed as much of it is probably gone. You can also consider Morpheus8. This nonsurgical treatment combines microneedling with RF technology to help tighten skin and improve the look of undereye bags. See an experienced provider near you to learn more.
