The name “karité”, widely used in Europe, comes from the Wolof word ghariti, meaning “sacred”. Through French traders the word eventually evolved into the term beurre de karité, which is still commonly used today.
the shea treeShea butter is obtained from the nuts of the shea tree (Vitellaria paradoxa), a tree native to West and Central Africa.
This remarkable tree can reach up to 15 meters in height and is known for its longevity. Similar to olive trees in the Mediterranean, shea trees can live for many decades and continue producing fruit for generations.
The tree thrives in the dry savanna regions of Africa and requires approximately 1000 mm of annual rainfall to produce its fruit. The nuts are harvested, dried and processed to obtain the rich butter that has become famous worldwide.
For centuries, women in these regions have used shea butter to protect their skin from harsh environmental conditions such as dry winds and intense sun exposure.
from shea nut to shea butterThe shea fruit contains a seed rich in lipids. After harvesting, the nuts are traditionally processed through drying, roasting and grinding. The paste obtained from this process is then kneaded and purified to produce the creamy butter we know as shea butter.
Besides its cosmetic use, shea butter is also used in cooking in several African countries, highlighting its cultural and economic importance.
composition of shea butterFrom a formulation perspective, shea butter is particularly interesting because of its fatty acid profile and its naturally occurring bioactive compounds.
Its main fatty acids include:
- oleic acid
- stearic acid
- palmitic acid
- linoleic acid
This composition gives shea butter a rich, creamy texture and excellent emollient properties.
Another important feature is its unsaponifiable fraction, which includes phytosterols, triterpenes and antioxidant compounds. These substances contribute to the soothing and protective properties associated with shea butter.
what shea butter does for the skinShea butter acts primarily as a rich emollient and barrier-supporting lipid.
It helps soften and smooth the skin, improve skin comfort and reduce moisture loss from the skin surface. Because of its fatty acid composition, shea butter helps reinforce the skin’s lipid barrier and improves the skin’s ability to retain moisture.
This makes it particularly beneficial for dry, rough or dehydrated skin. Its naturally occurring phytosterols and antioxidant compounds contribute to its soothing properties and help support the skin against environmental stress.
For this reason, shea butter is often included in formulations designed for sensitive, irritated or environmentally stressed skin.
The rich texture of shea butter also improves skin suppleness and elasticity, leaving the skin feeling softer and more comfortable after application.
Shea butter is commonly used in products such as:
- moisturizing creams
- body butters
- hand creams
- lip balms
- soothing balms and salves
Shea butter is also widely used in hair care formulations, particularly in products designed for dry, damaged or curly hair.
Thanks to its rich lipid composition, it helps soften the hair fiber and improve manageability. It forms a light protective layer on the hair shaft that reduces moisture loss and protects the hair from environmental stress.
In hair formulations, shea butter can help:
- improve hair softness
- reduce frizz
- protect the hair fiber from dryness
- add shine and smoothness
For this reason, shea butter is commonly found in products such as:
- hair masks
- conditioners
- leave-in treatments
- hair balms for curly or textured hair
Its creamy texture also helps improve the sensory profile of hair products, giving them a rich and nourishing feel.
refined vs unrefined shea butterTwo types of shea butter are commonly used in cosmetics.
Unrefined shea butter retains its natural aroma and color and contains slightly higher levels of minor bioactive compounds.
Refined shea butter has a milder scent and a more neutral appearance, which makes it easier to use in cosmetic formulations where fragrance or color must be controlled.
Both forms provide similar emollient and structuring properties.
shea butter in modern skincareShea butter has earned its reputation as one of the most versatile natural ingredients in skincare. Its rich lipid composition, soothing properties and luxurious texture make it a favorite among both formulators and skincare enthusiasts.
Whether used in body butters, nourishing creams, lip care products or hair treatments, shea butter continues to play an important role in modern cosmetic formulation.
