Butyrospermum Parkii (Shea Butter)
Ingredient Info
Shea butter is a natural fat extracted from the nuts of the shea tree, native to Africa. In skincare, it works as a moisturizer and conditioning agent, helping to soften and protect the skin by forming a protective barrier.
Benefits
- Deep moisturizing and hydration
- Skin conditioning and softening
- May help reduce appearance of dry patches
Potential concerns
- May cause sensitization in some individuals—formulations should be tested for non-sensitizing properties
- Quality varies depending on processing; impurities in poorly processed shea butter could be a concern
Science: A 2024 safety assessment by the Cosmetic Ingredient Review Expert Panel concluded that shea-derived ingredients are safe at current concentrations and practices of use when formulated to be non-sensitizing. The Panel noted that formulators should be aware of similar constituents in other botanical ingredients to avoid hazardous levels when combined, and should use good manufacturing practices to limit impurities.
