You are not too young.

I commonly treat young people with lower lid bags. It is usually a straight forward procedure to remove them - and they often do not reoccur. What you have has been inherited - it is not a sign of aging. It can usually be corrected without any external incisions. Look at my web site for some examples.

The New York Metropolitan area has many good board certified plastic surgeons who are experienced  in eye lid surgery. There is one that I can reccomend without reservation. Me. Should you wish to explore this further please go to my web site and pix.

Without examining you, it would be difficult to suggest what you should have done. If you have bags of fat in the lower lids, this can be easily treated by removing the fat from inside your eyelid. This will not leave a scar on the lower lid skin. Dark circles may be a pigmentation issue and again it is best to evalute in person. Good Luck.
