Suffer from Red/Pink patches that makes you feel embarassed? Put an end to your facial flushing. IPL /Laser treatment has two actions that help in Rosacea. Firstly, red thread veins absorb the light energy, this makes them hot. This damage encourages the body to reabsorb them, improving appearance. Secondly, the light energy warms the collagen fibres in the skin this stimulates new collagen and collagen remodelling, this improves the support of the small blood vessels which helps to delay the development of more thread veins.
