The ND-YAG laser can also treat capillaries of some substance (1-3 millimetres in diameter) and is currently considered the laser system that can give very good results for telangiectasia of the lower limbs, both superficial red ones and, in particular, blue ones. The effect of heat concentrated on the small blood vessels (capillaries) closes them, so that the pink or red-blue colour fades or disappears.
It is a vascular laser with high penetration through the skin. The capillary is closed by the laser energy, and the skin is not damaged at all. It makes it possible to remove, by cauterisation, both ruby angiomas and small capillaries, and it can be used for so-called permanent laser hair removal.
