Dermatitis

What is Dermatitis?

Dermatitis is a general term for inflammation of the skin, and it covers several different conditions with different causes. The most common types are atopic dermatitis (eczema), contact dermatitis and seborrheic dermatitis.^{[1, 2, 3]} None of them is contagious.

Common symptoms

Itching is the hallmark symptom, and it can be intense. Scratching irritates the skin further and keeps the cycle going.^[4]

• Red, inflamed skin
• Dry, scaly or cracked skin
• Blisters, oozing or crusting in some cases
• Swelling or tenderness
• Darker or lighter skin after a flare heals

Atopic dermatitis is marked by dry skin and lichenification (thickened, leathery skin from long-term scratching).^[1] Seborrheic dermatitis tends to appear as scaly, greasy patches on the scalp, face and body folds.^[3]

Causes and risk factors

Atopic dermatitis comes from a mix of immune system overactivity, inherited skin barrier changes and environmental factors. It often occurs alongside allergic rhinitis, asthma and food allergy.^{[1, 4]} Contact dermatitis is caused by exposure to irritants such as harsh soaps and solvents, or to allergens such as nickel or fragrances. It is a leading cause of work-related and hand dermatitis.^[2]

Seborrheic dermatitis affects skin rich in oil glands and tends to come and go in adults.^[3] Stasis dermatitis, which appears on the lower legs, is linked to poor circulation in the leg veins.

How it is diagnosed and treated conventionally

A doctor usually diagnoses dermatitis from the appearance of the skin and your history. Patch testing can identify the allergen in allergic contact dermatitis.^{[2, 4]} Seeing a doctor matters because several other skin conditions look similar.^[2]

For atopic dermatitis, daily emollients and soap-free cleansers are the base of care. Topical corticosteroids are the usual first-line treatment for flares, topical calcineurin inhibitors are another option, and ultraviolet phototherapy is used when these are not enough. Antibiotics treat secondary skin infection.^[4] For contact dermatitis, the key step is to identify and avoid the trigger, along with restoring the skin barrier and calming inflammation.^[2]

Why Dermatitis calls for a whole-person approach

Dermatitis is more than a surface problem. Immune activity, the skin barrier, itch, sleep and mood all affect one another, so a flare often involves more than the skin.

Medical treatment of the skin remains the foundation. Complementary care is aimed at the other parts of the picture that affect how people feel and cope.

The itch-scratch cycle

Intense itch leads to scratching, which damages the skin and causes more inflammation and itch.^[4] Reducing itch is therefore a central goal of any plan.

Sleep

Sleep problems are common in atopic dermatitis. A meta-analysis of 32 studies with about 86,000 participants estimated that 43.4% of people with atopic dermatitis have a sleep disorder.^[5]

Stress, anxiety and mood

An umbrella review found that atopic dermatitis is associated with a higher risk of depression and anxiety. The authors stressed that the link does not prove cause and effect.^[6] Living with visible, itchy skin can be hard, and supporting stress and mood is a reasonable part of care.

Skin barrier and triggers

Contact dermatitis depends on exposure to specific irritants and allergens, so identifying and removing them comes first.^[2] In atopic dermatitis, changes in the skin barrier make the skin more reactive to irritants.^[4]

Acupuncture for Dermatitis

What the research shows

Almost all acupuncture research is in atopic dermatitis, and it suggests possible benefit for itch and symptom scores. The evidence is limited by small, mostly short studies. We did not find trials of acupuncture for contact or seborrheic dermatitis.

A 2024 meta-analysis of 8 randomized trials with 463 participants found lower SCORAD scores (a measure of severity), lower itch scores and better quality of life with acupuncture. It found no clear difference in the EASI score or IgE level. The authors called for larger, higher-quality trials.^[7] An earlier meta-analysis of 8 trials with 434 participants, mostly done in China, found acupuncture better than conventional medicine for some measures. Most of its comparisons were not sham-controlled, so it could not separate the needling itself from other effects.^[8]

A sham-controlled trial of 36 adults with mild to moderate atopic dermatitis gave twice-weekly acupuncture for 4 weeks. Severity scores fell by about 12 points with real acupuncture and were essentially unchanged with sham, with no serious adverse events.^[9] A broader review of complementary treatments for acne, atopic dermatitis and psoriasis concluded the evidence was insufficient to recommend them.^[10]

How acupuncture may work

Researchers do not yet know exactly how acupuncture affects the skin. In a small crossover trial of 30 adults with atopic eczema, acupuncture at specific points reduced itch and shrank the skin's wheal-and-flare reaction to an allergen test, compared with no acupuncture.^[11] That points to an effect on allergic itch signaling, but it is one small study, and needling at non-acupuncture "placebo" points also lowered itch in part of it.

What treatment involves

Treatment uses fine, sterile, single-use needles placed at points on the arms, legs and body, usually left in place for about 20 to 40 minutes. The sham-controlled trial used two visits a week for 4 weeks.^[9] We reassess after a short course of visits. Needling should be avoided through broken or infected skin.

Serious problems are rare. In prospective studies about 9 in 100 patients had a minor reaction such as brief bleeding, soreness or redness at a needle site, and serious events occurred in about 1 in 10,000 patients.^[12] Tell the practitioner first if you have a bleeding disorder, take blood thinners, are pregnant, or have a pacemaker (relevant to electroacupuncture).

Ayurvedic medicine for Dermatitis

The Ayurvedic view

Ayurveda groups many itchy, oozing skin conditions under the name Kushtha, and eczema-like rashes are often described as Vicharchika.^[13] In this traditional framework, the rash reflects imbalance of the doshas, with Pitta and Kapha usually emphasized, along with impure blood (rakta). These are traditional categories, not biomedical diagnoses.

Therapies that may be used

Care is chosen for the individual and traditionally combines:

• Diet and daily routine adjusted to the person, often avoiding foods considered aggravating to the dosha involved
• Herbs, taken by mouth or applied to the skin, such as turmeric and neem
• Cooling or soothing oil preparations for dry, irritated skin
• Panchakarma cleansing procedures such as Virechana, where traditionally appropriate^[13]

Panchakarma is not appropriate during pregnancy, acute illness or frailty, or on skin that is infected, and it should wait until a doctor has assessed the rash. Herbal preparations applied to the skin (transdermal medication therapy) may be used, but no efficacy claim is made for them here.

What the research shows

The research on Ayurveda for dermatitis is very limited. We found no randomized controlled trials of Ayurvedic treatment for dermatitis. The published material is mainly case reports, such as one of a 45-year-old man with an itchy, oozing eczema-type rash on the feet. A single case report cannot show that a treatment works.^[13]

A systematic review of turmeric and curcumin in skin disease found 18 clinical studies across many conditions, including atopic dermatitis. It described early evidence of benefit and said the studies were limited.^[14] It does not show that turmeric treats dermatitis.

Herbal medicine for Dermatitis

Herbs and formulas that have been studied

Most research is on Chinese herbal formulas, taken by mouth or applied to the skin, for atopic dermatitis. These are usually multi-herb formulas, and the choice of herbs differs between trials.^{[15, 16]} Turmeric has been studied for skin conditions more broadly.^[14]

What the research shows

The evidence is limited and the trials are of low quality. A Cochrane review of 28 trials with 2,306 participants found that most had a high risk of bias and inconsistent results. It concluded there was no conclusive evidence that Chinese herbs, taken by mouth or applied to the skin, reduce eczema severity.^[15]

A 2023 meta-analysis of 17 trials with 1,624 patients found a higher overall recovery rate and a lower recurrence rate with Chinese herbal medicine. The benefit on severity scores was not robust, and there was no clear difference in EASI score or quality of life.^[16] A family-medicine review also concluded that evidence is lacking to support integrative medicine for atopic dermatitis.^[4]

Safety and herb-drug interactions

Herbs can cause problems on the skin itself. Reviews note that virtually all herbal remedies can cause allergic reactions, and that some Chinese herbal creams have been found to contain undeclared corticosteroids.^[17] This matters in dermatitis, where a new allergic reaction can look like a flare.

Oral Chinese herbs have been linked to serious liver injury, and Ayurvedic products may contain heavy metals.^[18] In one study, about one fifth of Ayurvedic medicines bought online contained detectable lead, mercury or arsenic.^[19] Herbs can also interact with medicines, including blood thinners, immune-suppressing drugs and antidepressants.^[20]

Herbs should come from tested sources and be prescribed individually by a qualified practitioner. Tell us about every cream, pill and supplement you use, and whether you are pregnant or breastfeeding or have liver or kidney disease.

Translating traditional medicine into modern biological language

The links drawn here are interpretation, not equivalence. Chinese medicine often describes itchy, red, oozing skin as wind, heat or damp-heat in the skin, and dry, scaly skin as blood deficiency or dryness. Researchers study things that loosely parallel this picture: allergic itch signaling, skin blood flow and the skin's inflammatory response.^[11]

Ayurveda's aggravated Pitta and Kapha describe heat, redness and oozing, and impure blood describes a systemic cause of skin disease. No study has shown that a dosha or a pattern corresponds to a specific immune or skin process.

How this care fits with your medical care

Integrative care for dermatitis is complementary. Keep seeing your doctor or dermatologist, keep using prescribed creams and medicines as directed, and do not stop or change them without your prescriber. We do not diagnose the type of dermatitis, so a new or changing rash should be evaluated by a physician.

Please bring your diagnosis, any patch test results, a full list of creams, medicines and supplements, and notes on known triggers.

When to seek urgent medical care

Some skin symptoms need prompt medical attention, because dermatitis can become infected or can resemble a more serious skin reaction.^[4]

• Skin that is painful, swollen, warm or leaking pus, especially with fever
• Clusters of painful blisters or punched-out sores in an area of eczema
• A rash that spreads quickly over much of the body, or skin that is red and peeling widely
• Swelling of the face, lips or tongue, or trouble breathing
• A rash that began after starting a new medicine
• Eye pain or vision changes with a facial rash

If any of these occur, call 911 or go to the nearest emergency department.
