Solar Purpura vs. Solar Lentigines
Similarities:
- Both are triggered by chronic sun exposure and are more common in older adults.
- They affect areas of skin that have been exposed to sunlight over many years.
- Preventive measures like using sunscreen and covering the skin can reduce their occurrence.
Differences:
- Solar Purpura involves the breaking of small blood vessels, causing red or purple bruises on the skin, especially on the hands and forearms.
- Solar Lentigines are flat, dark spots (also known as sunspots) that appear on sun-exposed areas of the skin.
- Solar purpura results from fragile blood vessels, while solar lentigines are caused by excess melanin production.
