Thread veins and spider veins are harmless but are considered a cosmetic nuisance. These thin veins form as thin lines, webs, or branches and can appear red, pink or purple. Veins carry blood towards the heart and they contain valves which help the blood to continue travelling in this same direction.
When there is damage to the veins and the valve in the vein is disturbed or blocked, this results in the pooling of blood within the vein which enhances the appearance of the vein at the surface of the skin. When this pool of blood bursts, it branches out and creates a web resulting in spider veins. Spider veins on the face are caused by the tiny vessels bursting and can also be a result of pressure on the veins or sun damage.
These veins can be removed by your doctor using sclerotherapy or if they are smaller, your aesthetician can target them with a laser which destroys the veins.
