  Shea Butter

Raw, unrefined Shea Butter is rich in nutrients that protect your skin against dryness, fine lines, inflammation and acne.

    1) Shea Butter contains Antioxidants

     

    Antioxidants work by preventing unstable molecules from damaging skin cells.  

    The Shea tree Vitellaria paradoxa is slow-growing and long lived.

    Shea grows wild in the dry savannah regions of Africa and endures extreme heat, drought and wind. 

    In response to the harsh environment, Shea becomes stronger and makes antioxidants to help protect itself against damage.  

    Shea butter from the hottest, driest growing regions has the highest levels of antioxidants- including vitamin E (1) and triterpenoids (2)

    Shea butter is rich in a variety of antioxidants, including vitamin E, triterpenoids and polyphenols that help protect skin against sun damage and premature aging (1-3).  

    Shea butter is rich in polyphenols similar to green tea, including catechins, as well as quercetin and trans-cinnamic acid, compounds with strong antioxidant activity (3).

     

     

    2) Shea Butter Improves Dry Skin

     

    Shea Butter can penetrate deep into the skin layers, leaving skin feeling soft, smooth and supple. Shea butter has been shown to improve dry skin in children with eczema (4).

    Shea Butter re-hydrates dry, chapped skin and diminishes the appearance of fine lines around your eyes, mouth and forehead.  

     

    3) Shea Butter Repairs The Skin Barrier

     

    Shea Butter contains linoleic acid (5), the essential n-6 fatty acid found naturally in the skin barrier (6). Linoleic acid is the natural precursor for ceramide, a bioactive lipid that plays a role in maintaining skin barrier to protect against water loss (6).

     

    4) Shea Butter Calms Inflammation

     

    Shea butter has traditionally been used to calm irritated skin, and has been shown to improve symptoms of eczema (4). Shea butter contains active compounds, including triterpene cinnamates and acetates with anti-inflammatory activity (7).  

    Shea butter extract has been shown to significantly reduce the levels of LPS-induced nitric oxide, tumor necrosis factor-α (TNF-α), interleukins, 1β (IL-1β), and -12 (IL-12) in cell culture experiments (8). 

    Shea butter extract is thought to calm inflammation by targeting iNOS and COX-2 signalling pathways (8).

     

     

    5) Shea Butter Helps Fight Acne

     

    Shea butter contains up to 60% oleic acid, an omega-9 fatty acid found naturally in the skin layer with antibacterial activity. Oleic acid can increase the antimicrobial peptide beta-defensin-2, which can kill acne-causing bacteria (9).

    Shea butter also contains lupeol, a pentacyclic triterpene that has been shown to reduce acne induced inflammation by suppressing the NF-κB pathway in sebocytes and skin cells (10). 

    Shea Butter is non-comedogenic and does not clog pores.
