From popular herbs like ginkgo and ginseng to omega-3s and vitamin E, certain supplements can thin the blood and increase the chances of bruising. Add to that medications like aspirin or blood thinners, and even everyday painkillers like ibuprofen, and your risk grows.
Age-related changes, sun-damaged skin, and medical conditions such as diabetes or blood disorders can also contribute. While most bruises are harmless and heal with rest and ice, persistent or unusual bruising should prompt a visit to your doctor. It could be a warning sign of something more serious—and early action can make all the difference.
