Broken blood vessels are fine red veins that are visibly enlarged and can sometimes be seen on the chin, cheeks, or nose. There are a variety of reasons that cause facial broken blood vessels. Some examples would be estrogen replacement therapy, pregnancy, sun damage, Rosacea, or simple aging. If a person suffers from this condition they may choose to have laser treatments to reduce the appearance of the blood vessels. This is a relatively safe procedure with little to no side effects.
