The mechanism behind Shea Butter is precise: Rich in oleic, stearic acids and triterpene alcohols (anti-inflammatory); occlusive and emollient. That specificity is what separates it from broader-category ingredients that work in less targeted ways.
The scientific name is Butyrospermum Parkii Butter. Rich in oleic, stearic acids and triterpene alcohols (anti-inflammatory); occlusive and emollient. This mechanism is consistent across properly formulated products, which means the real variable is concentration and delivery system.
Typical working concentration is 2–30%. Best suited to dry, normal, sensitive skin. Primary applications: deep moisturisation, barrier repair, anti-inflammatory.
Works well with: Ceramides, free fatty acids. Avoid combining with: May clog pores for some acne-prone.
Unrefined shea retains more actives (vitamins A, E, cinnamic acid); comedogenic rating 0.
