My under-eyes are deeply sunken and look like dark circles. Is it safe to get under-eye fillers?

Even though I slept soundly for over ten hours over the weekend before going to work, it breaks my heart whenever my colleagues ask why I look so haggard or if I pulled an all-nighter. The skin under my eyes has sunken deeply, casting deep shadows along the bone contours; even though it’s not pigmentation, my overall impression always looks worn out and exhausted. When I try to cover the shadows with concealer by layering tone-up products, the thin skin around my eyes can't withstand it and cracks, making it look like I've actually created three or four more wrinkles. I haven't been able to get it done because I read that since the skin around the eyes is so thin and blood vessels are so visible, fillers can bulge out or show a bluish tint if injected incorrectly. Has anyone successfully managed to completely erase that haggard dark look by just subtly filling in the sunken areas? Please share your experiences regarding the recovery process and your satisfaction level after the procedure.
