I think these are malar bags? What can I do? Should I get surgery or fillers? (photos)

Eyelid fat bags are best corrected by surgery but there are some nonsurgical options that work sometimes. Surgery is not for everyone. In today's day and age, there are many nonsurgical options to consider although surgery usually gets the most improvement specifically of the malar or lower eye fat bags.I would recommend that you see a board-certified plastic surgeon in your area that is a member of both ASPS & ASAPS and performs a lot of mini facelifts and eyelid lifts but also offers all the nonsurgical options such as injectables and laser treatments. Go over your concerns with them and make sure above all, you walk out of there with several options and an idea of the pros and cons to each of them as well as realistic expectations. I hope this helps and wish you all the best in your surgery and event.

These are festoons. They are fluctuating swellings caused by accumulation of fluids as a result of a loss in elasticity and thinning of the skin.Surgery is a last resort as you will be substituting the swelling for a visible scar.The key to management is strengthening and thickening the skin. Typically, I'd put my patients on a retinol based skincare routine and then add on a course of CO2 laser tx or microneedling after 6-8 weeks.It's important to accept that the festoon are unlikely to completely disappear; treatment will only render them less obvious. And continuing skin care is is important.
