Spider veins can be blue, purple, or red and may appear in the form of thin lines, webs, or branches. People sometimes also refer to them as thread veins.
A range of treatments can remove spider veins or reduce their appearance.
In this article, we discuss the causes of spider veins and how they differ from varicose veins. We also cover the treatment and prevention of spider veins.
In the legs, spider veins can occur when the valves inside the veins stop working properly.
Veins carry blood back to the heart. To prevent blood from flowing backward, they contain a one-way valve that closes once the blood passes through it.
If this valve weakens or becomes damaged, the blood may struggle to flow in the correct direction, and it can begin to pool inside the vein. Over time, this can cause a bulge in the vein that branches out, resulting in spider veins.
Spider veins on the face are often the result of tiny blood vessels bursting. Increased pressure or sun damage can cause this to occur.
Spider veins are really small superficial veins that are in the outer layer of skin between the dermis and epidermis, so you can see them. Varicose veins are larger veins that are deeper in the body. “You won’t see them as a discoloration, you’ll see them when they get so stretched out that they kind of bulge.
Depending on their severity, varicose veins can cause a variety of symptoms. These may include:
swelling of the legs or ankles
an achy or heavy feeling in the legs
Varicose veins may also increase a person's risk of blood clots and circulation problems.
The target substance of vascular disease treatment is oxyhemoglobin in red blood cell in blood vessel. Wavelength affects laser’s depth of penetration. Under 1200nm, the longer the wavelength, the deeper laser can penetrate. Thus, laser wavelength is usually longer in vascular disease treatment so as to give consideration to target tissues’ selective absorption and penetrability. Besides, laser penetrates the epidermis melanin barrier and reaches targeted blood vessels. Short wavelength laser light will be competitively absorbed by epidermis melanin, which will cause epidermis injury and form cicatrix. 980nm Diode 980nm Laser Therapy system takes advantage of 980nm wavelength laser, penetrating epidermis and reaching blood vessels. Based on selective photothermolysis theory, oxyhemoglobin absorbs laser energy and produces thermal energy and spreads to vascular endothelial cells through conduction mechanism. In consequence, blood vessel wall is damaged and facial vascular will be treated.
The major targeted chromophore in facial vascular treatment is oxyhemoglobin that existing in red blood cell in vessels. According to the curve of laser absorption by targeted substance (right picture), oxyhemoglobin shows a much higher absorption interval in 900nm-1000nm. Thus 980nm semi-conductor laser has the ideal treatment effects for facial vascular removal.
