👉 Beta veins are small, thin-walled veins that are located just beneath the skin's surface. They are usually not visible to the naked eye and are often associated with larger veins. Beta veins play an important role in draining blood from the skin back to the heart, but they can become enlarged or inflamed due to various factors such as injury, inflammation, or underlying medical conditions. These veins may appear blue or purple under the skin's surface and can be a sign of a more serious health issue if left untreated.
