What is solar purpura?
Solar purpura is a condition where long term sun damage to the skin causes easy bleeding into the skin tissue with even slight injury. This appears as spots or patches of bruising that is red to purple in color. It is a harmless condition and is not related to skin cancer which is also associated with prolonged sun exposure. The elderly are more often affected as age-related changes coupled with prolonged sun damage weakens the blood vessels in the skin. Solar purpura is also known as actinic purpura or senile purpura due to its prevalence in seniors. It is the deeper layer of the skin, known as the dermis, which is affected. Solar purpura is often missed as a diagnosis as it takes only minimal sun exposure to cause the condition as a result of years or decades of blood vessel weakening.
