Vascular lesions are the result of numerous or large vessels that form directly underneath the skin. This usually results in a red appearance in the skin since the vessels can be visible through the skin. These lesions occur in many sizes, shapes and forms all over the body.
The skin has an extensive network of veins and tiny blood vessels called capillaries. Over time, as a result of different factors such as sun, hormones, medication, skin type and mechanical damage, many people suffer from broken capillaries and rosacea(which is a network of broken capillaries is one concentrated area).
Dehydrated, dry, sensitive and lighter skin types provide less protection against the elements and therefore, these skin types are most commonly affected. On the face, broken capillaries mostly occur around the nose, cheeks and chin but may be found on others areas as well.
IPL treatment works by directing well controlled pulses of light into the upper skin. The light is absorbed by one of the body’s own natural substances – haemoglobin – contained in the red blood cells.
Haemoglobin converts the light energy into heat. This heat is transferred to the walls of the blood vessels, which are permanently damaged and removed by the body’s own defence mechanism. The method of converting light to heat and using it to destroy the target without damaging the surrounding tissue is called Selective Photothermolysis.
The visible light produced by the IPL systems is carefully controlled to produce the correct pulse length and right amount of energy to destroy the vessel. Best results are obtained on patients who have light to medium skin.
Using the 480nm module, the IPL delivers high intensity computer controlled pulses of light that penetrate the skin and is absorbed by the affected areas without damaging surrounding healthy skin.
The heat energy causes coagulation of the haemoglobin (oxygen) in the veins, causing the blood vessels to close off. The skin is left with a more even skin colour and an overall smoother and more radiant appearance.
Radiofrequency ablation is a minimally invasive treatment for varicose veins. (Ablation means a doctor uses heat to damage tissue, which makes scar tissue form. This scar tissue closes the vein.) This technique uses radiofrequency energy (instead of laser energy) to heat up and damage the wall inside a vein.
E-light delivers pulses of light energy which cause the blood within the vein to coagulate, eventually destroying the vessel which is later reabsorbed by your body. Blood flow will then be redirected to veins deeper below your skin’s surface – where it should be.
Q-Switch lasers has been shown to be effective in treating vascular lesions like telangiectasia, cherry angiomas, and small spider nevi. More than one treatment could be required.
However, it can cause purpura which could take up to a week to clear.
ND:YAG can be used to remove spider and thread veins in the face (cheek, temporal region, nasal dorsum, forehead) and legs.
Some vascular birthmarks (capillary vascular malformations)
Varicose veins in the leg
Facial veins (telangiectasis)
Haemangiomas (vascular tumours) in the face and around the mouth
The laser light pulses target red pigment (haemoglobin). Typical settings employed for the treatment of facial veins include a 50 milliseconds pulse duration, and fluence (ie output energy) of 150¬250 J/cm2 (measured in Joules per centimetre squared).
