IPL skin rejuvenation Maidstone is used to treat spider veins, also known as telangiectasias, the light generates heat in the veins. As with other spider vein treatments, this causes the walls of the vein to collapse and form scar tissue. Eventually, these veins will be reabsorbed by the body and fade away after several weeks. In general, IPL affects the lower layers of the skin, rather than the top. This allows it to reach deeper structures, like the spider veins, without burning the surface of the skin.
