What the Science Says
Shea butter is a fat extracted from the seeds of the African shea tree (Vitellaria paradoxa). Applied to skin, it acts as an emollient — softening and protecting the skin barrier by reducing water loss and soothing irritation. Active compounds called triterpenes (lupeol, α-amyrin, β-amyrin) appear to support wound healing by reducing inflammation, stimulating collagen production, and promoting skin cell regeneration, though most clinical evidence comes from small studies.
What It Doesn't Do
Not proven to heal wounds faster than standard care on its own — study differences weren't statistically significant. No evidence it works as an oral supplement. Won't cure eczema or atopic dermatitis by itself. Not a sunscreen. No proven anti-aging effects from the provided research.

Absorption & Bioavailability
Unknown for oral use; topical absorption is assumed based on mechanism but not formally measured in provided studies
Red Flags to Watch For
- Most clinical evidence comes from very small studies (as few as 20–34 participants) — results may not generalize
- Shea butter is often used in multi-ingredient formulas, making it hard to isolate its specific effects
- Fragrance-allergic individuals should note shea butter appears safe, but always patch-test new topical products
- Suppository and industrial (PFAS removal) uses found in research are not relevant to typical consumer supplement use
