Thread veins: What are they and how can I get rid of them?

Thread veins, also known as telangiectasia, are prominent clusters of small, damaged blood vessels visible in the skin. Those tiny red, blue or purple lines that appear just under the surface? They're capillaries that have dilated and become visible.

While both men and women develop thread veins, research has shown 79% of adult males and 88% of adult females have leg telangiectasia. A total of 1322 (84%) of the population were classified as having telangiectasias in their right legs; 555 (79%) of men and 767 (88%) of women. Telangiectasia is so common in the general population, especially in women, as to represent the norm. The difference becomes more pronounced with age, and hormonal factors play a significant role.

Why do thread veins appear?

As we age, our skin produces less collagen and becomes thinner. Spider veins result from abnormalities in the horizontal vascular plexus of capillary loops in the skin and can have either arterial or venous origins. This makes the dilated blood vessels underneath more visible, particularly on the face and legs.

Thread veins often develop alongside rosacea, that frustrating condition that causes persistent facial redness and flushing. There was a highly significant association between the degree of severity of varicose veins and the grade of telangiectasia. Less than 1% of subjects with grades 2–3 trunk varices were free of telangiectasia, but 51% of subjects with grades 2–3 telangiectasia had no clinical evidence of varicose veins.

Several factors can trigger their appearance:

• Sun exposure (the most common culprit)
• Hormonal changes during pregnancy, menopause, or from the Pill
• Genetics (if your parents had them, you're more likely to develop them too)
• Weight fluctuations and prolonged standing
• Alcohol consumption

The good news? You don't need to resort to expensive procedures to manage thread veins. Here's how to improve their appearance naturally.

1. Protect your skin from UV damage

Sun exposure isn't just the most common trigger for thread veins, it's also the most preventable. UV damage weakens the collagen and elastic fibres that support your blood vessels, making them more likely to dilate and become visible.

During peak sun hours (10am to 4pm), seek shade and wear a wide-brimmed hat. For daily protection, our British Summer Time SPF 30 provides mineral sun protection without irritating sensitive skin. Unlike chemical sunscreens that can trigger redness, this zinc oxide formula creates a physical barrier while priming your skin for makeup.

2. Strengthen your skin with targeted ingredients

The right combination of natural actives can make a real difference to thread veins. Look for ingredients that calm inflammation, boost collagen production, and strengthen capillary walls.

Research has shown that rose hip oil is beneficial for sensitive skin, thread veins, capillary damage or weakness & very effective in promoting tissue regeneration. Our Rosehip BioRegenerate Oil is particularly effective because CO2 extraction preserves 700% more antioxidants than cold-pressed oils, including trans-retinoic acid (a natural form of vitamin A) that supports skin renewal.

For immediate calming when thread veins are inflamed, reach for Instant Kalmer. This serum contains sea aster and schisandra berry, two potent anti-inflammatory actives that reduce redness within minutes. Apply it to clean skin before your moisturiser for best results.

3. Support collagen production

While rosehip oil itself doesn't contain vitamin C (a common misconception), rosehip oil does contain high levels of beta-carotene (an antioxidant), all-trans retinoic acid (a vitamin A acid that retinol converts to and which has similar effect to retinol when applied topically), omega-3 and omega-6. These compounds work together to support your skin's natural collagen synthesis.

The Anthemis Chamomile Cream combines German chamomile CO2 extract with ceramides and squalane to strengthen the skin barrier while calming redness. It also has anti-inflammatory properties that can help reduce redness and inflammation caused by conditions such as rosacea or eczema. A stronger barrier means less visible thread veins over time.

4. Mind your alcohol intake

That glass of wine causes immediate flushing because alcohol dilates blood vessels. In regular drinkers, these vessels lose their ability to contract properly, remaining permanently visible as thread veins.

You don't need to be teetotal, but moderating intake can prevent new thread veins forming. Also check your skincare for ethyl alcohol, a known rosacea trigger that can worsen thread veins. All Pai products are alcohol-free for this reason.

5. Choose antioxidants that actually work

Antioxidants protect against free radical damage from UV exposure, pollution, and other environmental stressors that weaken blood vessel walls. But not all antioxidants are created equal.

Our Age Confidence Serum delivers NAD+ co-enzyme technology through biofermented niacinamide. This isn't just another antioxidant, it's a cellular energiser that helps skin cells repair damage more effectively. Combined with our Rosehip oil's naturally occurring lycopene and beta-carotene, you're giving your skin serious protection.

6. Exfoliate gently (emphasis on gently)

Harsh exfoliation thins the skin, making thread veins more visible. Those scrubs with jagged particles? They create micro-tears that weaken your skin barrier and inflame existing thread veins.

If you must exfoliate, our Resurface Mask uses fruit AHAs to dissolve dead cells without physical abrasion. Use it once weekly, maximum. On other days, a soft muslin cloth with your cleanser provides all the exfoliation most skin needs.

When to see a dermatologist

While these natural approaches can significantly improve the appearance of thread veins, some cases benefit from professional treatment. Most patients seek treatment options such as sclerotherapy, intense pulsed light therapy, thermocoagulation, or microphlebectomy. However, telangiectasias are often a cosmetic concern, and treatments primarily focus on improving appearance.

See a dermatologist if thread veins are painful, rapidly spreading, or affecting your confidence. They can assess whether underlying venous issues need addressing. Patients who present with capillary telangiectasia should have colour duplex scanning because roughly 25% will have clinically unapparent long or short saphenous incompetence. Research has shown that 88–89% of women with telangiectasia have refluxing reticular veins close, and 15% have incompetent perforator veins nearby.

The bottom line on thread veins

Thread veins are incredibly common, especially in women over 40. While you can't change your genetics or stop the ageing process, you can absolutely minimise their appearance with the right skincare approach.

Daily SPF, anti-inflammatory ingredients, and gentle treatment of your skin make the biggest difference. And remember, what works for one person's thread veins might not work for yours. Give any new routine at least 12 weeks to show results, and be patient with your skin.
