Coconut oil (virgin)

What it is

Virgin coconut oil is pressed from fresh coconut flesh without heat or bleaching, which keeps its natural scent and antioxidants. Unlike most plant oils it is nearly all saturated fat, and about half of that is lauric acid, a fatty acid with well-documented antibacterial activity^{2, 3}.

What the evidence says

Evidence: moderate for atopic eczema, especially in children; lab-only for acne; none for sun protection.

Two randomised trials from the Philippines are the backbone of the evidence. In 117 children with mild to moderate atopic dermatitis, eight weeks of virgin coconut oil twice daily reduced eczema severity scores by 68%, against 38% with mineral oil, and improved water loss through the skin more¹. In 52 adults with atopic dermatitis, four weeks of coconut oil cleared Staphylococcus aureus, the bacterium behind many eczema flares, from 95% of carriers, compared with 50% on virgin olive oil². Both were small studies, so "moderate" is the fair label. Our eczema and dry skin guide shows where an oil fits in a routine.

For acne, lauric acid kills acne bacteria in the laboratory at far lower concentrations than benzoyl peroxide and reduced acne-like swelling in mice³, but no human trial has tested coconut oil on spots. The oil is heavy, and many people who use it on the face report clogged pores and new breakouts. If you are acne-prone it belongs on the body, not the face; our oily skin guide explains why.

Coconut oil is not a sunscreen. The "SPF 7" or "SPF 8" figures you may see for it come from a test-tube absorbance calculation that looked only at UVB, not from the standardised test on people that produces a real SPF, and they say nothing about UVA⁴. When plant oils were later measured against approved UV filters, they absorbed at least a hundred times less UV⁶. Dermatologists recommend broad-spectrum SPF 30 or higher⁵, so an oil leaves skin essentially unprotected. See our sun protection guide for options without a white cast.

How people use it

• As a body moisturiser: a pea-sized amount warmed between the palms and smoothed onto damp skin after bathing, once or twice a day.
• On eczema-prone patches: twice daily on unbroken skin, alongside any prescribed treatment rather than instead of it.

Cautions

• Patch test first; allergy is rare but possible, particularly with scented or blended products.
• Keep it off the face if you get blackheads, whiteheads or breakouts.
• Never use it as sunscreen or to "extend" time in the sun^{4, 5, 6}.
• Do not apply it to infected, weeping or cracked eczema; see a clinician first.
• Use clean, dry fingers or a spatula so that bacteria do not grow in the jar.
