The Bottom Line

Stasis dermatitis is a type of eczema that develops on the lower legs when the veins cannot efficiently return blood to the heart. This causes fluid and pressure to build up in the leg tissue, which inflames the skin over time. It affects about 6 to 7% of adults and becomes even more common after age 70. Unlike most skin conditions treated mainly with creams, stasis dermatitis is best treated by addressing the root cause — poor venous circulation — primarily through compression stockings. About 70 to 80% of people improve significantly within 12 weeks with proper compression therapy.

What Is Stasis Dermatitis?

Stasis dermatitis (also called venous dermatitis, gravitational dermatitis, or venous eczema) is a skin condition that develops on the lower legs — particularly the inner ankle and lower shin area — as a result of chronic venous insufficiency. "Venous insufficiency" means the vein valves in your legs are not working well, so blood pools in the leg instead of flowing efficiently back to the heart.

When blood pools, pressure builds in the small capillary blood vessels near the skin. Fluid and inflammatory cells leak out of these capillaries into the skin and tissue, causing swelling, inflammation, and over time, significant skin changes. Unlike contact dermatitis or atopic eczema, stasis dermatitis is driven by a circulatory problem — which is why compression therapy (not just skin cream) is the cornerstone of treatment.

Signs and Symptoms

Stasis dermatitis almost always affects the lower legs, usually both legs, with the inner ankle (medial malleolus) area being the most common spot. Symptoms develop gradually and typically include:

  • Redness, scaling, and itching on the inner lower leg and ankle
  • Swelling (edema) in the ankle and lower leg — often worse by end of the day and better in the morning
  • Brown or reddish-brown discoloration of the skin from iron deposits (hemosiderin staining)
  • The skin may feel thick, leathery, or hard over time
  • In active flares: the skin may weep or crust over
  • In long-standing cases: the skin may become tight, hard, and woody-looking (lipodermatosclerosis)
  • In severe or neglected cases: a venous leg ulcer may develop — an open wound that is very difficult to heal

What Causes Stasis Dermatitis?

The root cause is venous insufficiency — when the valves inside the leg veins stop working properly. Normally, these valves act like one-way doors pushing blood upward toward the heart. When they fail, blood flows backward and pools in the lower leg veins, raising the pressure in the blood vessels near the skin.

Risk factors for developing venous insufficiency and stasis dermatitis include:

  • History of deep vein thrombosis (blood clot in the leg)
  • Varicose veins
  • Pregnancy (multiple pregnancies especially)
  • Prolonged standing or sitting at work
  • Obesity — extra weight increases pressure in leg veins
  • Heart failure or kidney disease (which cause fluid retention)
  • Age over 50 (valve function naturally declines with age)
  • Family history of venous disease

Treatment Options

Compression therapy (the most important treatment): Graduated compression stockings are the cornerstone of stasis dermatitis treatment because they directly address the venous hypertension causing the problem. Compression stockings (20 to 30 mmHg at the ankle) squeeze the leg from the ankle upward, helping blood return to the heart efficiently and reducing the pooling pressure. Most people see significant improvement in 12 weeks. You will likely need to wear compression stockings long-term — stopping them leads to recurrence in 60 to 80% of people within a year. Compression must be applied in the morning before getting out of bed when swelling is least.

Leg elevation: Elevating your legs above heart level for 30 to 60 minutes, 3 to 4 times daily, reduces the hydrostatic pressure in leg blood vessels and decreases swelling. Regular calf raises and ankle flexion exercises also improve circulation by working the calf muscle pump.

Topical corticosteroids: For active inflammation, itching, and redness, a mild-to-moderate strength steroid cream (such as triamcinolone 0.1% or fluticasone lotion) used twice daily for 2 to 3 weeks reduces inflammation effectively. Steroids should not be used on open sores or for extended periods without medical supervision, as long-term use can thin the already fragile skin.

Moisturizers and skin care: Apply fragrance-free moisturizers (CeraVe cream, Eucerin) generously to the affected skin twice daily. This repairs the skin barrier and reduces itching and cracking. Avoid harsh soaps, irritating products, and potential allergens — people with stasis dermatitis are prone to contact allergies, especially to ingredients like lanolin, neomycin, and fragrances.

Treating bacterial infections: If the skin becomes infected (increased warmth, spreading redness, pus, or fever), oral antibiotics are needed. Your doctor will often take a swab culture to identify the bacteria before prescribing antibiotics.

Addressing the veins: A vascular specialist may be able to treat incompetent (leaky) veins through endovenous laser ablation or radiofrequency ablation — minimally invasive procedures that close off the problem veins. Treating the underlying vein disease can significantly improve stasis dermatitis and reduce the risk of leg ulcers.

When to See a Dermatologist

  • You have redness, itching, scaling, or brown discoloration on your lower legs, especially around the ankles
  • Your lower legs have been swollen for more than a few weeks
  • An open wound or sore develops on your lower leg — this needs prompt evaluation for venous ulcer
  • The skin becomes hot, more swollen, or develops pus — signs of bacterial infection (cellulitis)
  • Your symptoms are not improving after 4 to 6 weeks of consistent compression stocking use
  • You are unsure whether you have stasis dermatitis or another skin condition (such as cellulitis, contact dermatitis, or psoriasis)

Frequently Asked Questions

Why are compression stockings so important?

Compression stockings directly treat the root cause of stasis dermatitis — the abnormally high venous pressure in your lower leg blood vessels. Without compression, even the best creams and medications only treat the surface symptoms while the underlying pressure keeps damaging the skin. With compression stockings, 70 to 80% of patients experience significant improvement or complete resolution within 12 weeks. Think of it this way: no amount of moisturizer can fix a problem that is being driven by circulatory pressure.

Can stasis dermatitis develop into a leg ulcer?

Yes, if left untreated or inadequately managed, stasis dermatitis can progress to a venous leg ulcer in about 10 to 15% of patients over 5 years. Venous ulcers are open wounds on the lower leg that are notoriously slow to heal and can become chronically recurrent. The best way to prevent them is consistent long-term use of compression therapy and proper skin care. Early, aggressive treatment of stasis dermatitis is the most effective way to avoid this complication.

Is stasis dermatitis the same as cellulitis?

No, but they can look similar and both can be present at the same time. Stasis dermatitis is a chronic inflammatory skin condition caused by poor venous circulation. Cellulitis is an acute bacterial skin infection. Stasis dermatitis typically affects both legs, comes and goes with activity levels and time of day, and has the characteristic hemosiderin (brown iron) staining. Cellulitis typically affects one leg, progresses rapidly over hours to days, often causes fever, and feels very hot and tender. A dermatologist can help distinguish between them since the treatments are quite different.

Do I have to wear compression stockings forever?

For most people with chronic venous insufficiency, yes — long-term compression stocking use is needed to keep symptoms under control. About 60 to 80% of people who stop wearing their stockings develop a recurrence within 12 months. However, if the underlying venous problem is treated directly (such as through laser ablation of incompetent veins), some patients can reduce or stop compression. Your dermatologist or vascular specialist can advise based on your specific situation.
