Many sites present olive oil as a solution for eczema and psoriasis. The truth is more measured: it's a good moisturising fat, but the evidence is limited and, for eczema in particular, some studies point to a skin-barrier risk. Here's a cautious approach.
- Olive oil is an emollient: it softens and limits water loss from dry, scaly skin.
- For eczema (atopic dermatitis), studies suggest olive oil's oleic acid may weaken the skin barrier — caution is warranted.
- It does not treat or cure eczema or psoriasis, which require dermatological care.
- Never apply to broken, weeping or infected skin without medical advice, and patch-test first.
Why it's used on dry skin
Olive oil is an emollient rich in oleic acid, squalene and vitamin E. On dry, thick or scaly skin, it forms a film that softens and limits water evaporation. This explains its traditional use on psoriasis plaques and dry areas.
The important point about eczema
For atopic dermatitis (eczema), honesty is needed: several studies suggest that olive oil, because it is high in oleic acid, can impair the skin barrier and is not ideal on fragile eczematous skin. Emollients formulated for atopy are generally preferred. In other words, the popular remedy is not a scientific consensus.
Psoriasis: a supportive use
On psoriasis, olive oil can help soften scales and moisturise, alongside — never instead of — prescribed treatment. A gentle massage with warm oil on thick plaques may help lift scales, but it does not treat the underlying disease.
Precautions
Always patch-test on a small area. Do not apply to broken, cracked, weeping or infected skin without medical advice. If lesions worsen, stop. Eczema and psoriasis are chronic conditions needing dermatological care: olive oil replaces neither a suitable emollient cream nor medical treatment.
Frequently asked questions
Is olive oil good for eczema?
It moisturises, but its value for eczema is debated: high in oleic acid, it may weaken the skin barrier already impaired by atopic dermatitis. Emollients designed for atopy are often preferred. Ask a dermatologist.
Does olive oil cure psoriasis?
No. It can help soften and moisturise plaques as a supportive measure, but it does not treat psoriasis, which requires medical care and often specific treatment.
How do you apply olive oil to dry skin?
In a small amount, on clean and preferably still-damp skin, with a gentle massage. Avoid broken or infected areas and do a tolerance test first.
Which oil for eczema if not olive oil?
Dermatology guidance often favours emollients formulated for atopy. Some oils higher in linoleic acid are considered more barrier-friendly. Ask a professional.
Can you put olive oil on a wound or weeping skin?
No, not without medical advice. On broken, cracked or infected skin, applying it can make things worse. See a doctor.
