Did you know that in general, women bruise more easily than men because their skin is thinner? People also bruise more easily as they age, because the skin gets thinner and blood vessels become more fragile. We also bruise more easily if our skin has sun damage. Natural redheads also bruise more easily, compared to people with brown or blonde hair. It has something to do with a mutation of the gene that controls pigment.
Bruising could also have something to do with medications you may be taking, ones that thin the blood – like ibuprofen or aspirin, or prescription blood thinners. Some supplements and foods can also have a blood-thinning effect, mostly things that we associate with good heart health, like fish oil and vitamin E, and foods like garlic and ginger.
