INCI: Butyrospermum Parkii (Shea) Butter
Plant butter from shea tree nuts. Rich in fatty acids and unsaponifiables with anti-inflammatory properties. Intensely softens skin and restores the barrier.
Topical application
BLimited evidence. One RCT or several controlled studies with limitations.
Clinical studies demonstrate efficacy in xerosis, eczema, and dermatitis. The unsaponifiable fraction contains lupeol and alpha-amyrin with proven anti-inflammatory activity. Reduces TEWL better than mineral oil.
Shea butter (Butyrospermum Parkii Butter, Karite Butter) is a plant butter from shea tree nuts (Vitellaria paradoxa), growing in West African savannas. Cold-pressed or extracted. Solid butter texture, melts on skin at body temperature. Composition: 40-50% oleic acid (omega-9), 30-40% stearic, 5-10% linoleic, up to 10% unsaponifiable fraction – not ceramides here, but triterpenes, phytosterols, tocopherols, allantoin, trace retinol. Unique fraction. Shea unsaponifiables (5-15% vs 1-2% in most oils) are responsible for anti-inflammatory and regenerative action. Triterpene alcohols (lupeol, α- and β-amyrins) inhibit cyclooxygenase-2 and reduce prostaglandin synthesis. A rare combination for a plant oil. Where applied. Body and face creams and butters, barrier-repair products, atopic skin products, lip balms, infant products, lipsticks. In Spain – in Bioderma Atoderm, La Roche-Posay Lipikar, Mustela Stelatopia, Babé. Concentration 1-100% (as pure body butter). Evidence base. Verallo-Rowell 2008 (RCT, n=20, atopy) showed SCORAD improvement comparable to ceramide products. Hon 2015 in children with atopy – reduced TEWL and improved barrier. Israel 2015 in psoriasis – reduced scaling. Evidence quality for barrier repair – A/B (one of the most studied plant oils). Refined vs unrefined controversy. Unrefined shea – yellow color, characteristic grassy aroma, maximum active unsaponifiables. Refined – white, odorless, partially loses active triterpenes and vitamin E, but more convenient in cosmetic formulas. For best effect on atopics and damaged skin – unrefined. Safety. CIR confirmed shea butter safety (Final Report 2017). Hypoallergenic, non-comedogenic (by actual data, not by internet 'comedogenic scales' – rating 0). Allergic reactions are rare even in people with nut allergy (shea is not a true nut botanically). Pregnancy and lactation – safe. A natural food butter (used in cooking in Africa), no topical restrictions at any stage, on any skin including breast and nipples during lactation.
