I look tired, so I'm considering getting eye fillers.

My under-eyes look noticeably empty and dark, making my complexion look very poor. Even after getting a good night's sleep, people around me always ask if I look tired or if I'm sick, which is so stressful. It's not just a one-time thing... it's really stressful. As the furrows under my eyes deepen, the fat above them appears to protrude slightly in comparison, making the shadows look even darker.

Even when I try to cover it up with concealer, the skin around the eyes is so thin that the makeup just gets stuck in the wrinkles and looks patchy, failing to cover the sunken, sagging, and shadowed areas at all. So, I would like to smooth out this area with under-eye fillers. Is that possible?

However, the skin under the eyes is so thin that I am really worried about side effects. Also, since it is around the eyes, I think I would be really scared when the needle goes in during the procedure. Does it not hurt a lot?
