Skin collagen breaks down with age, leading to thinner skin, which makes it easier for bruises to appear.

Prevention points out that bruises are also simply more apparent on people who naturally have fair, thin skin. Individuals with higher levels of fat beneath the skin do not show bruises as easily.
Individuals who are deficient in vitamin C also bruise more readily, Prevention observes. Low levels of this nutrient are often seen as people age and in alcoholics with poor diets. Vitamin C contributes to the production of collagen, a component needed to make skin thicker and sturdier.
Prevention also highlights several medical issues that cause easy bruising. Varicose veins, spider veins and naturally prominent veins are more likely to show a rupture when bumped. Several diseases cause vasculitis, or inflammation of the blood vessels. The irritated blood vessels are prone to bursting, which leads to bruising. In addition, purpuric dermatosis is characterized by capillaries leaking blood. This condition, often seen in the elderly, leads to thousands of tiny bruises.Learn more about Skin Conditions
