What is a Venous Lake
A venous lake is a dilated ‘lake-like’ venule in the upper dermis typically seen on the lips or ears of elderly patients. These lesions are dark-blue to purple, soft, raised nodules, usually 2 to 10 mm in diameter.
It is a small blood vessel (vein) in the skin, which has enlarged and wider (or broader) over time.
What causes a venous lake?
It is thought that long-term sun exposure can cause venous lake and possibly smoking, although the cause is unknown.

What is the cause of a Venous lake
The cause of a venous lake still needs to be understood entirely. The most likely reason is chronic sun damage to the walls of the superficial veins. This damage leads to the dilation of veins on the skin’s surface, resulting in an elevated, dark blue papule.
While most venous lakes appear on the lip, they can also form on the neck, ears, or backs of the hand. A venous lake is not painful or dangerous. These lesions can be effectively eliminated using a vascular laser device at our clinic.
