Shea Butter, an overview.
Shea butter is made from the fat extracted from the nuts of the shea tree, a plant native to West Africa (almost all of the shea butter used today still comes from this region). Historically, it has been used by indigenous populations for centuries, both as a topical application and as a cooking butter (food-grade shea butter is still used for cooking today). Currently, it is most well-known for its use in the beauty industry.
Shea butter is rich in triglycerides, fatty acids, and vitamins. When applied topically, shea butter is an excellent emollient and can help the skin reduce its moisture loss. Shea butter is incorporated into a plethora of lotions, creams, and more... It is found under the I.N.C.I. name 'Butyrospermum Parkii Butter (Extract)'.
Shea butter for moisturizing dry skin.
The most apparent advantage, of course, is its moisturizing and nourishing properties. Its qualities are tied to its high fatty acid content - and due to the types of fatty acids it contains (namely linoleic acid and oleic acid), it tends not to be greasy and is easily absorbed.
In fact, the fatty acids contained in shea butter are divided into three categories: monounsaturated fatty acids, polyunsaturated fatty acids, and saturated fatty acids. These molecules contribute to hydration by strengthening the skin's protective barrier, which is itself made up of fatty acids. As a reminder, skin hydration is maintained by the presence of the hydrolipidic film which prevents evaporation and keeps hygroscopic molecules within the cells.
It has been demonstrated that this vegetable butter seals moisture into the skin and protects the skin barrier. A study even suggests that it has topical effects similar to those of ceramides, the polar lipids naturally present in the epidermis and responsible for the impermeability of the skin barrier.
Due to its virtues, shea butter is indeed included in the composition of our nourishing body cream. Enriched with squalane and shea butter, this treatment reduces feelings of tightness by restoring the skin's lipid film.
Shea butter, a restorative and anti-inflammatory agent.
Skin repair, whether it's from breakouts, acne lesions, or other issues, can be a lengthy process. (Some scars never truly disappear either.) However, the addition of topical products that help strengthen the skin barrier and possess antioxidant properties can be beneficial. In fact, in one study, researchers found that topical shea butter could improve the appearance of the skin, the immune response, and the healing time of certain lesions.
Furthermore, shea butter contains bioactive ingredients that give it anti-inflammatory properties. A 2015 study consisting of 25 individuals suffering from mild to moderate eczema revealed that shea butter can help alleviate the signs and symptoms of eczema.
Shea butter, effective against wrinkles.
Shea butter helps to counteract the effects of sun exposure and skin aging by promoting cellular renewal. Additionally, it helps to restore skin elasticity, which is necessary for smoothing features and reducing wrinkles. These properties stem from the simultaneous action of vitamins A and D, as well as phytosterols. With its antioxidant action, it also prevents the appearance of new wrinkles. It's worth noting that premature skin aging results from the degradation of skin proteins due to the action of free radicals.
In which Typology skincare products can one find shea butter?
Ournourishing face creambased on hyaluronic acid contains a significant portion of shea butter. Thanks to its content of moisturizing and lipid-replenishing active ingredients, this treatment provides suppleness to the skin. Furthermore, it reduces feelings of tightness. It is suitable for normal, combination, and dry skin types.
You can also find this vegetable butter in the firming night mask based on prickly pear oil, a nourishing balm to nourish and regenerate weakened skin, and firm up the tissues.
Shea butter is also present in our gel-in-oil stretch marks
with baobab oil to prevent and visibly reduce the appearance of stretch marks, while providing flexibility and elasticity to the skin.
Finally, our two solid cleansing treatments cold-processed (CP) and 100% natural, are enriched with shea butter.
