“Spider veins” are characterised by thin hair-like veins that usually appear on the legs or face. The condition, is generally harmless and painless but one might find its appearance undesirable.
Spider veins occur when the walls of small, superficial, microscopic blood vessels in the legs or face become weakened and thus dilate and become visible. The cause is strongly genetic, but this can be aggravated by an increased pressure in the blood vessels caused by obesity, age, pregnancy, hormonal imbalances or other genetic factors.
Telangiectasias are characterised by blue or red spider web-like appearance and reticular veins are slightly larger spider veins but still part of the microcirculation.
