Shea butter in skincare: the claims and the evidence
Shea butter is the original rich moisturiser, and the published studies are small, short or about products that contain more than shea. Here is what we can say.
You may see it written as
- Butyrospermum Parkii Butter
- Shea Butter
What has been tested
A study in a Hong Kong paediatric dermatology clinic asked 34 children with atopic dermatitis to try a cream and a cleanser containing a lipid complex with shea butter extract for four weeks. About three-quarters rated both as very good or good. Among the children who rated the cream well, the mean itch score fell from 6.7 to 6.0, which was statistically significant.1 It had no placebo group, and it tested a combined product, not shea butter alone.
A 1996 study in 21 healthy volunteers applied nine lipids once, plain shea butter among them, to normal skin and to skin irritated with a detergent (sodium lauryl sulphate), with water as the control. On normal skin none of them differed. On irritated skin, shea butter did not reduce the irritation compared with water, while hydrocortisone, canola oil and a sterol-rich canola fraction each did better on at least one measure.2 It was a single application, so it says little about using shea butter every day.
A 2025 laboratory study of a barrier cream containing shea butter, an ingredient listed as silkflo, and vitamin E found it was non-toxic to skin cells, reduced oxidative stress and increased collagen synthesis in a keratinocyte cell line. That is a dish experiment on a mixture.3 Three of its eight authors work in research and development at a skincare company.3
What we cannot say
None of these is a trial of shea butter on its own for dry skin or eczema. The eczema study had no control group, and the controlled study used one application on deliberately irritated skin. Shea butter works as a rich emollient because that is what a plant fat does, but that is reasoning, not a finding from these papers.
If you like shea butter, your skin is a better judge than the literature at this point. Try a small area first.
Using shea butter with other products
We did not find a source saying shea butter has to be kept apart from other ingredients, or any study of it layered with actives. Because it is a heavy fat, a thick layer over another product is more a question of feel than of science, and we have no source on it.
Shea butter in pregnancy and breastfeeding
We found no pregnancy- or lactation-specific evidence for this ingredient.
Evidence on cosmetic products in pregnancy is limited overall, so ask your doctor or midwife about the specific product you use.4
What you will see on the label

A FEW MORE ANSWERS
Common questions about shea butter
Is shea butter good for dry skin?
We found no trial of shea butter alone for dry skin. One application of plain shea butter did not calm detergent-irritated skin better than water,2 and a 34-child eczema study of a cream with a shea butter extract had no placebo.1
Is shea butter good for eczema?
The one eczema study we read tested a cream and cleanser containing a lipid complex with shea butter extract in 34 children, with no placebo group.1 It does not show shea butter alone helps.
Is shea butter safe?
In 2024 the Cosmetic Ingredient Review expert panel assessed 13 ingredients derived from the shea tree, Butyrospermum parkii, and concluded they are safe as used in cosmetics when formulated to be non-sensitising.5 Snifff rates the butter Risk-free and found no pregnancy-specific evidence.
Is shea butter safe in pregnancy?
Snifff found no pregnancy-specific evidence for Shea butter. Ask your doctor or midwife about the product you use.
