Butyrospermum Parkii Butter (Shea)

Butyrospermum parkii butter is the INCI name of shea butter — the West African nut lipid prized for its high unsaponifiable fraction (up to 11%), which delivers anti-inflammatory triterpenes beyond simple occlusion. It reduces TEWL, cushions the barrier, and studies show effectiveness comparable to medium-potency barrier treatments for atopic skin comfort. In formulation at 2–20% it gives body and richness to creams and balms. For face use, combination skin should note its occlusive weight; for body, lips, hands, and winter care it is peerless. Fair-trade shea additionally supports women’s cooperatives in the Sahel — ethics and efficacy in one ingredient.
