What Causes Spider Veins? A Doctor's Guide to Prevention and Relief

Spider veins aren’t just a cosmetic concern—they can also be the first sign of underlying issues with circulation and vein health. As a physician and founder of Nurturelief, I created this guide to help you understand exactly what spider veins are, why they develop, and what science says you can do about them.

What Are Spider Veins?

Spider veins (also called telangiectasias) are tiny, dilated blood vessels that appear near the surface of the skin. They often show up on the legs or face and may look red, purple, or blue. While they are generally considered harmless, they can be a source of discomfort and self-consciousness.

Unlike varicose veins, spider veins are typically smaller and don’t bulge, but both conditions result from venous insufficiency—impaired function of the valves in the veins that regulate blood flow.

Who Gets Spider Veins?

Spider veins are very common. Studies suggest that nearly 50% of women and up to 45% of men will experience some form of vein issue by the age of 50 (American Society for Dermatologic Surgery). Risk factors include:

• Genetics (a family history is the strongest predictor)

• Prolonged standing or sitting

• Hormonal shifts (pregnancy, menopause, hormonal birth control)

• Aging

• Sun exposure (particularly on the face)

• Obesity or excess weight

• Sedentary lifestyle

Why Do Spider Veins Form?

Spider veins occur when small blood vessels near the surface of the skin dilate due to increased pressure or weakened vessel walls. Normally, veins have valves that keep blood flowing toward the heart. If those valves weaken or become damaged, blood can pool, causing the veins to swell.

There is strong scientific consensus around several contributing factors:

• Heat can cause vasodilation, increasing the appearance of spider veins (Journal of Vascular Surgery, 2012).

• Inactivity reduces venous return and can lead to venous pooling.

• Hormonal changes—especially during pregnancy—can soften vein walls due to elevated progesterone levels.

Are Spider Veins Dangerous?

From a clinical standpoint, spider veins are usually considered a cosmetic issue. However, their presence can sometimes be a sign of chronic venous insufficiency (CVI). According to the American Venous Forum, when accompanied by symptoms such as swelling, aching, or fatigue, a deeper venous evaluation may be warranted.

Common symptoms include:

• A feeling of heaviness or fatigue in the legs

• Itching or burning sensations near the veins

• Mild swelling around the ankles

Can You Prevent Spider Veins?

While not all spider veins are preventable—especially if you have a genetic predisposition—there is clinical evidence that lifestyle modifications can reduce their occurrence or severity:

• Exercise: Studies show that regular low-impact activity like walking can improve venous return (Clinical Hemorheology and Microcirculation, 2004).

• Compression stockings: Help prevent blood from pooling in the legs (Cochrane Review, 2014).

• Leg elevation: Enhances drainage of blood toward the heart.

• Weight management: Reduces pressure on leg veins.

• Avoiding prolonged sitting or standing: Particularly important in professions like nursing, teaching, or retail.

How Nurturelief Supports Leg and Vein Wellness

Many creams claim to improve spider veins, but few include ingredients backed by scientific research. That’s why we formulated Nurturelief Micronized Diosmin Vein Contour Cream with active compounds that have real data behind them:

• Micronized Diosmin + Hesperidin: Numerous clinical studies (e.g., Daflon 500 studies) show these flavonoids, when taken orally, can support microcirculation and reduce symptoms of chronic venous insufficiency. While topical absorption data is limited, micronization is known to improve bioavailability and skin penetration. The addition of penetration enhancers like menthol and plant oils further facilitates transdermal delivery.

• Botanicals including Butcher’s Broom, Horse Chestnut, Centella Asiatica, Calendula, and Pinus Pinaster Bark Extract: These plant-based ingredients have been studied for their vasoprotective and anti-inflammatory properties. For instance:

  • Butcher’s Broom (Ruscus Aculeatus) has shown efficacy in reducing leg swelling and improving venous tone (Phytomedicine, 2010).

  • Horse Chestnut (Aesculus Hippocastanum) extract has been found to reduce leg pain and swelling in people with CVI (Cochrane Review, 2006).

  • Pinus Pinaster Bark Extract (Maritime Pine) is rich in proanthocyanidins that offer vascular antioxidant protection.

• Menthol: Offers cooling relief and may enhance penetration by mildly disrupting the skin barrier (Journal of Pharmacy & Pharmacology, 2001).

• Sweet Almond, Jojoba, and Grapeseed Oils: Hydrate and nourish the skin while providing a luxurious, non-greasy finish.

Our cream is plant-based, cruelty-free, and made in an FDA-registered, GMP-compliant facility.
