If you bruise easily and regularly, you should certainly have this checked by your GP. There may be an underlying problem with the way your blood coagulates (clots). Even if your blood clots perfectly normally, you may occasionally become bruised through, for example, some cosmetic procedures or surgery. Then you'll benefit from a cream which fades bruises slightly faster. Big bruises can take two to three weeks to fully resolve. A good vitamin K cream such as Aestheticare Auriderm XO can speed this up by several days, while helping to soothe traumatised skin.
