Within 1 or 2 days, the hemoglobin (an iron-containing substance that carries oxygen) in the blood changes and your bruise turns bluish-purple or even blackish. After 5 to 10 days, the bruise turns greenish or yellowish. Then, after 10 or 14 days, it turns yellowish-brown or light brown.

Do some bruises never go away?

Bruises arent usually serious, and they often clear up without treatment. If you have a bruise that doesnt go away after 2 weeks, you bruise for no apparent reason, or you have additional symptoms, see your doctor for diagnosis. The sooner you get treatment, the sooner youll start feeling better.

Does rubbing bruises help it heal faster?

Dont massage or rub the injury because you can break more blood vessels in the process. Instead, give yourself time for the pain and swelling to subside and apply ice immediately and as needed.
