Your under-eyes look hollow and sunken, giving you a tired impression.

I'm worried because the area under my eyes looks particularly hollow lately. It's not like I'm not getting enough sleep, but people around me frequently tell me I look tired. When I look closely in the mirror, the area under my eyes is slightly sunken, and there is a shadow below that, making it look like dark circles. Even when I apply concealer, the sunken parts remain, so there is a limit to how much I can cover it up with makeup.

Is hollowness under the eyes caused simply by a lack of fat? Or could it also occur as skin elasticity decreases with age or as the location of the under-eye fat shifts? Since the treatment method seems to vary depending on the cause, what procedure should I consider?

I have heard many recommendations for procedures like under-eye fillers or skin boosters, and I am wondering if they are helpful for naturally adding volume. The skin around the eyes is sensitive and thin, so I am concerned about side effects. I would appreciate it if hospital staff could answer whether unevenness or prolonged swelling can occur after the procedure, and how the treatment plan is determined.
