You can't speed up losing a bruise but with the application of some cover up make up you make it appear to have gone... add a pair of glasses and job done. Whether male or female.... make sure the colour of the cream matches the rest of the surrounding skin.
Arnica cream is supposed to help with bruises.
I think Sqad has the right answer though. Years ago, I had a terrible black eye. There was not much I could do after putting ice on it to bring down the swelling, and then makeup and sunglasses, as MallyJ said.
Henry not much you can do as others have already said will be 2 to 3 weeks before it goes naturally, although some ice cubes or frozen peas wrapped in a towel may give some partial relief rather than cure.
