Spider veins are small, thin veins that appear red, blue, or purple and commonly form on the legs and face due to weakened blood vessels. Cherry angiomas, on the other hand, are small, bright red growths caused by an overgrowth of blood vessels. These conditions can be influenced by genetics, aging, sun exposure, and hormonal changes. While they are generally harmless, many people seek treatment for cosmetic reasons or to prevent further progression.
