Spider Naevi
What are Spider Naevi?
Spider naevi (also called spider angiomas or spider telangiectasias) are small, visible blood vessels that spread out from a central red spot, resembling a spider’s web. They are usually harmless but may sometimes indicate an underlying health condition, especially if they appear in large numbers.
Causes
Spider naevi occur when small blood vessels (capillaries) dilate close to the skin surface. Common causes include:
Physiological factors
- Common in children and young adults
- Pregnancy (due to hormonal changes, particularly oestrogen)
Medical conditions
- Chronic liver disease (e.g., cirrhosis)
- High oestrogen levels
- Thyroid disease
Lifestyle factors
- Sun exposure
- Excessive alcohol use
Symptoms / Signs
- Red central spot with fine blood vessels radiating outward
- Blanching (fades temporarily) when pressed with a finger
- Most common on the face, neck, upper chest, arms, and hands
- Usually painless, but some may cause slight burning or sensitivity
Treatments
Professional Treatments
- Laser therapy (vascular laser or IPL) – destroys abnormal blood vessels safely
- Electrocautery – uses heat to seal off blood vessels
- Treatment of underlying cause – e.g., managing liver disease or hormonal imbalance
At-Home / Supportive Care
- Avoid excessive sun exposure
- Use SPF 30+ sunscreen daily
- Limit alcohol consumption
- Gentle skincare to avoid further irritation
Prevention
- Protect skin from UV damage (sunscreen, hats, shade)
- Avoid excessive alcohol intake
- Maintain healthy liver function
- Manage hormonal balance if relevant
- Regular skin checks if you are at risk
FAQs
Q1. Are spider naevi dangerous?
Usually no – they are often harmless. But multiple lesions may be a sign of liver disease and should be assessed by a doctor.
Q2. Will they go away on their own?
Sometimes – in children and during pregnancy, they often fade naturally. Otherwise, they may persist without treatment.
Q3. Do spider naevi mean I have liver disease?
Not necessarily – a single or few spider naevi are common. But widespread spider naevi can indicate cirrhosis or liver issues, so medical evaluation is important.
Q4. Can skincare creams remove spider naevi?
No – topical creams cannot remove them. Only laser or medical procedures are effective.
Q5. Is treatment permanent?
Yes, treated spider naevi usually don’t return, though new ones can develop if triggers (sun, liver disease, hormones) persist.
