There are many different types of laser and light treatment products on the market used to treat the visible symptoms of skin conditions including rosacea.
One of the most popular branded laser treatments for rosacea is VBeam. VBeam uses a pulsed dye 595nm laser. VBeam is produced by the Candela corporation and is sold to dermatologists around the world.
The visible blood vessels underneath the skin associated with conditions such as rosacea and vascular lesions, give rise to dark areas which can be targeted by a filtered laser.
A non invasive technique, VBeam treatment involves targeting these darker areas with a laser whilst leaving the surrounding areas of lighter skin undamaged.
During treatment, the VBeam DCD (dynamic cooling device), sprays cryogen to cool the skin milliseconds before a pulsing laser targets the haemoglobin below the skin. This cooling helps protect the outer skin layer (epidermis) and reduces the risk of blistering and bruising (purpura).
Each pulse of the laser is brief lasting fractions of a second. The laser is directed manually by a practitioner using a hand held device with the laser pointed at the skin.
VBeam can be used to treat many skin conditions (see below). In rosacea, spider viens (telangiectasias) are targeted – these are tiny broken blood vessels beneath the skin. Spider veins contain haemoglobin – the protein found in red blood cells which contains the red pigment present in the blood.
Haemoglobin within the blood vessels is heated which causes the veins to collapse and fade in color. This reduces redness of the skin in the area affected by rosacea.
Laser treatment for rosacea usually requires only three to six sessions. In some cases only one or two may be required.
