What eczema is
Eczema, also called atopic dermatitis in its most common form, is a long-term skin condition that causes dry, itchy, inflamed skin. It often starts in childhood but can begin at any age. It tends to come and go: periods of flare-ups are followed by calmer stretches. In lighter skin the patches may look red, while in darker skin they can look brown, purple or gray, and the skin may thicken from scratching.
The exact causes are not fully understood. A weakened skin barrier, immune system activity and genetics all seem to play a part, and eczema often runs in families alongside asthma or hay fever. Because a weakened barrier loses moisture and lets irritants in, people with eczema prone skin usually need to be more careful with what touches their skin.
Eczema is not contagious, and it is not caused by poor hygiene. Other conditions can look similar, including contact dermatitis, psoriasis and fungal infections, so a proper diagnosis from a doctor is important. Please do not decide for yourself that a rash is eczema.
Common triggers
Triggers differ for every person, and many flares have no obvious cause. Things that are commonly reported include:
- Dry air and temperature changes, including cold winters and heated rooms
- Hot water and long baths
- Soaps, cleansers and detergents, especially harsh or heavily scented ones
- Fragrance and some preservatives or plant extracts in skin products
- Rough fabrics, such as wool
- Sweat and heat
- Stress or poor sleep
- Allergens such as dust mites, pollen or pet dander, for some people
- Infections, since eczema skin is more prone to them
Some people link food to flares, particularly children, but this is complicated and should be explored with a doctor or dietitian instead of by cutting foods out on a guess.
Why soap choice matters
Cleansing removes dirt, sweat and germs, but it also removes some of the skin’s natural oils. For eczema prone skin, the aim is to wash only as much as needed, gently, and then restore moisture. Conventional soap, including traditional bar soap, is alkaline compared with the skin’s naturally slightly acidic surface. Skin pH explains this in more detail. Some people with eczema find standard bars drying or irritating, while others tolerate certain gentle ones. Reactions vary, and there is no soap that is guaranteed safe.
General points often mentioned for choosing a cleanser:
- Keep it simple. Fewer ingredients make it easier to see what you react to. Learning to read ingredient lists is a useful skill.
- Skip fragrance and essential oils where possible. Unscented soap and fragrance-free options reduce one common source of reaction. Sensitive skin and fragrance goes further into why.
- Avoid abrasives. Soaps with oatmeal, seeds or other texture may feel too rough on inflamed skin, so exfoliating soap is not usually a good match during a flare.
- Consider non-soap cleansers. Some doctors recommend soap-free or emollient washes for eczema prone skin, in place of any soap. This is worth asking about.
- Think about extra oils. Handmade soap with a higher share of conditioning oils left unsaponified is sometimes described as milder, as explained in soap superfatting. This is a recipe idea, not a promise that a bar will suit eczema, and sensitive skin soap discusses what claims are reasonable. Ingredients like goat milk, honey or oatmeal are popular, but any of them can trigger some people.
- Rinse well and pat dry.
Handmade soap is not a treatment for eczema, and no soap can cure it. If you make soap for someone with eczema, be honest that it cannot be guaranteed to suit them, and suggest a patch test.
Washing and moisturizing habits
- Bathe or shower in lukewarm water, and keep it short.
- Wash with your hands rather than rough cloths or sponges.
- Apply a plain, thick moisturizer soon after bathing while skin is still slightly damp, and again through the day. Creams and ointments are often better tolerated than light lotions.
- Wash laundry with fragrance-free detergent and rinse thoroughly.
- Avoid bubble bath, bath bombs and heavily scented bath products during flares.
- Try new products one at a time and patch test them on a small area first. A patch test is not a guarantee, but it catches obvious reactions.
- Keeping a product journal can help you notice patterns.
Skin care for children with eczema is covered in children skin, and winter dryness is covered in flaky skin. Natural moisturizers explains some of the ingredients you may see in creams.
Treatment is for a professional
Eczema is a medical condition, and many people need treatments beyond moisturizers, such as prescription creams or other therapies. Natural remedies are not a substitute, and some, such as undiluted essential oils or certain plant extracts, can worsen the skin. Please do not stop prescribed treatment in favor of a home remedy.
When to see a doctor
Please consult a doctor or dermatologist if:
- you think you or your child may have eczema and have not had a diagnosis
- the skin is very itchy, sore, cracked or weeping
- you see signs of infection, such as yellow crusts, pus, spreading redness, warmth or fever
- itching disrupts sleep or daily life
- over-the-counter moisturizers and gentle habits are not enough
- a baby has a persistent rash
