Diffuse redness is a general appearance of facial redness, such as rosy cheeks. This condition is caused by dilated capillaries, resulting in an appearance of general redness, not discrete, well-defined vessels. The most commonly affected areas are the nose, forehead and cheeks. Diffuse redness is often associated with a common condition called rosacea and it can be hereditary. Laser Genesis will help your appearance by gently treating and reducing this condition.
