Thread Veins

Thread veins are among the undesirable signs of aging that appear on the skin. In a clearly biased manner, these veins tend to be more prevalent in women than in men, seemingly due to hormonal influences. Thread veins can cause the skin to look uneven in tone, contributing to an older appearance.

FAQ - THREAD VEINS
What are thread veins?
Thread veins are capillaries (tiny channels that connect your veins and arteries) that have expanded and appear as thin red lines on the face and legs. They often gather around the nose and cheeks, and in the thigh or calf area. The colour in thread veins is due to haemoglobin, the red protein that transports oxygen in your blood.
Thread veins are commonly called ‘spider veins’ because they spread out in various directions, or ‘broken veins’ because they resemble veins leaking blood. Despite these dramatic names, they simply refer to capillaries, which everyone has near the skin's surface that have enlarged and become more noticeable.
The scientific term for thread veins is telangiectasia, a complex Greek word where telos means ‘end’, angeion means ‘vessel’ (as in ‘blood vessel’), and ektasis means ‘becoming dilated’.
What causes thread veins?
Thread veins are partly hereditary and partly influenced by lifestyle or environmental factors. Excessive exposure to ultraviolet light (from bright sunlight or even daylight), wind or extreme temperatures can age the skin. Similar to the skin, thread veins lose elasticity as we age. If your skin tends to flush red easily, the repeated stretching of the veins can cause them to lose elasticity more quickly. Once the veins remain enlarged, they become visible on your face. Thread veins are often seen in heavy drinkers because alcohol causes blood vessels to dilate and the face to flush.
Does ageing cause thread veins?
While age isn't a direct cause of thread veins, it does contribute to their appearance. As we get older, our blood vessels lose elasticity, causing facial veins to gradually enlarge and become more noticeable. Additionally, aging makes the skin thinner, which further highlights these under-the-skin blood vessels.
Is it possible to eliminate thread veins with skincare?
While some skincare products might temporarily reduce the appearance of thread veins slightly, they will not eliminate or remove them. The most effective use of skincare in this context is to conceal prominent thread veins using a high-coverage concealer.
How can I prevent thread veins?
It's not possible to completely prevent thread veins, so don't be too hard on yourself if they start to appear. However, you can take these five steps to delay their onset and minimise their visibility:
Care for your skin by keeping it clean and moisturised, exfoliating regularly, and using sunscreen.
Limit alcohol consumption. Alcohol can worsen thread veins by causing blood vessels to dilate and stretch.
Avoid very hot beverages, as they can also aggravate thread veins.
Stay away from saunas. While extreme heat can help cleanse your skin through sweating, it may also promote thread veins.
Steer clear of spicy foods. Dishes like vindaloo or those containing Scotch Bonnet peppers can make your face flush, temporarily making thread veins more noticeable.
Can I permanently remove thread veins?
Yes, procedures like laser, intense pulsed light and microneedling can permanently eliminate your existing broken veins. However, as your skin ages naturally, these treatments will not prevent thread veins from developing so you may need future treatments to remove these.
What is the best treatment for thread veins?
There are multiple highly effective treatments available for thread veins. The most suitable treatment depends on the size, location and colour of your thread veins. Your skin tone may also influence your treatment options, as laser and intense pulsed light devices may not be effective on darker skin.
Microneedling is particularly beneficial as it not only addresses thread veins but also improves overall skin texture and appearance. It is a versatile treatment that can complement other therapies for a more comprehensive approach to skin rejuvenation. Also known as medical needling or Collagen Induction Therapy (CIT), Microneedling uses tiny needles to create small holes in the skin's surface. This process stimulates a wound-healing response and boosts collagen production, the protein that provides skin structure and firmness. When done correctly, microneedling can refresh the skin's surface and reduce thread veins.
Intense Pulsed Light (IPL) is highly effective for treating thread veins, as the light energy targets the red hemoglobin pigment in the veins, breaking it down so the body can disperse it. You may require multiple treatments, depending on the extent of the veins.
Using a laser to treat thread veins is a fast and effective method for clearing them. It's not entirely pain-free as lasers are designed to emit concentrated beams of light at a specific wavelength and depth in the skin. To treat thread veins, the practitioner targets the hemoglobin, the red pigment in your thread veins, breaking it into tiny fragments. Each thread vein requires only a few quick zaps, so the pain, though intense is brief. Over the following week or so, the thread veins gradually disappear as your body disperses the fragmented pigment.
Sometimes referred to as thermocoagulation, the microwave method involves placing a fine, insulated needle just above the vein and passing a microwave current through it every 2mm along the vein's length. The heat energy from the low-level microwave current causes the vein to close and be absorbed by the body, disappearing almost immediately.
