How can I get rid of sallow skin?

How can I get rid of sallow skin (pale Yellowish skin) ? Has anyone recovered from sallow skin? What supplements can I take to get rid of sallow skin?

My original skin tone was medium-fair, but unfortunately my skin has changed to sallow (pale yellow). It is not like jaundice-type yellowing; it looks more like a pale yellow tone. My eyes are also a normal color. Has anyone else experienced this? I would really appreciate it if someone who has gone through this could share how they permanently got rid of sallow skin.
