Treat dilated leg veins - the vascular lesions which cannot be removed by IPL Just the facts A large number of men and women all over the world suffer from disorders of the blood vessels (vascular lesions). These can be of various types, from small telangiectasias (sometimes called spider veins or broken veins) to large Port Wine Stains.
Vascular lesions are normal veins that have dilated under the influence of increased venous pressure.
Whereas classical IPL works for certain smaller leg veins, it is generally accepted that Nd:YAG technology is much more effective than IPL for the majority of leg veins. | |
Clinically proven, safe and effective How does an Nd:YAG laser work? To clear leg veins, the vessels must be constricted. A 1064 nm wavelength Nd:YAG laser sends energy into the blood and vessel walls, where it is absorbed by blood. Red blood cells are heated, causing met-haemoglobin formation and greater absorption. This causes microclotting and heating of the vessel wall, leading to complete or partial collapse. The constricted vessel then degenerates, and the visible leg veins disappear from the surface of the skin. How does an Nd:YAG laser work on leg veins? Treating vascular conditions in general is based on the principle of selective photothermolysis performed with a single pulse.
A condition of good results is that the Pulse Time is chosen noting the thermal relaxation time for the actual vessel thickness.
The ideal immediate response to treatment with vascular laser is coagulation of the vessel with no other apparent effect. This effect can be observed in the form of bluish or greyish discolouration visible on the skin surface. In leg veins, blanching or disappearance of the vessel may occur. Why is the Nd:YAG laser better than I²PL for treatment of leg veins? Leg vessels are normally deep, which is why Nd:YAG in most cases respond better than IPL.
I²PL is good for treatment of very superficial small vessels or blanching after sclerotherapy. Note that lasers or light can only be used 1 month post sclerotherapy.

When dealing with homogenous redness like PWS, rosacea or fine telangiectasias, I use the I²PL (PR or VL applicator). For leg veins or thicker telangiectasias I use the Nd:YAG applicator. All three options in a single system!” Prof. Michael Drosner, Institute for Laser Research in Dermatology, cutaris Center, Munich, Germany |
