As we get older, we may notice that small veins begin to show through the skin, particularly on the face and neck. Most commonly these viens are a result of a genetic predisposition, smoking, or prolonged exposure to sunlight. These veins are known as thread veins and usually occur on the face or legs.
Thread veins may be purple, blue, or red in colour, and although not harmful, can be unsightly. However, they do have the potential to develop into more painful, and serious, varicose veins, so it is better to treat thread veins before this occurs.
