What is a Venous Lake?
A venous lake is a vein, or small blood vessel in the skin, which over time has become enlarged and slightly bulbous in appearance. It can be seen as a soft dark blue to purple spot which can measure up to 1 cm in size. It can be most commonly found on lip borders. The cause is thought to be due to sun exposure resulting in a dilated blood vessel/capillary. A laser treatment can safely and effectively treat these lesions and minimally invasive too.
