SHEA BUTTER

Shea Butter has been treasured across West Africa for centuries, where the nuts of the shea tree are transformed into a rich botanical butter unlike almost any other. Its reputation for nourishing dry skin is well known. What is far less known is the sophisticated chemistry behind it.

Beyond its fatty acids, Shea contains an unusually valuable unsaponifiable fraction rich in triterpenes, phytosterols, tocopherols and phenolic compounds. These bioactive components are where Shea begins to look less like a familiar moisturizer and more like a remarkably complex botanical treatment for the skin.

Shea's triterpenes have been studied for anti-inflammatory activity and their relationship with the structures responsible for youthful-looking skin. Research has explored effects involving collagen production, collagenase and elastase—enzymes associated with the breakdown of collagen and elastin. These are the proteins that help give skin its firmness, strength and elasticity, making Shea particularly relevant to body skin showing crepiness, loss of firmness and changes in elasticity.

There is another little-known quality of Shea: naturally occurring cinnamate compounds have UV-absorbing properties. Research has examined Shea in photoprotection and its ability to enhance UV protection within tested sunscreen formulations. Shea is not sunscreen, but this natural chemistry, combined with its antioxidant compounds, adds another dimension to its role in helping defend skin against environmental stress.

And then there is what Shea does exceptionally well: transform the feel of very dry body skin. Its rich lipids envelop rough, moisture-depleted areas and help slow water loss, bringing softness and flexibility back to skin that feels parched or coarse. Elbows, knees, hands, legs and feet become smoother and more supple, while dry, crepey texture takes on a richer, more conditioned appearance.

That combination of deep lipid nourishment and support for elasticity also makes Shea especially beautiful for skin that has been stretched or changed over time. While no botanical butter can erase stretch marks, keeping the skin exceptionally supple and conditioned can improve the appearance and texture of the surrounding skin, making areas of uneven texture look smoother and more refined. Shea is one of beauty's great botanical materials—not because it is familiar, but because beneath that familiarity lies an extraordinary combination of triterpenes, essential lipids, antioxidant compounds, anti-inflammatory activity, collagen and elastase research and naturally occurring UV-absorbing compounds.

In The Signature Body Butter™, Shea is treated accordingly: not as a basic moisturizing butter, but as a luxurious, bioactive foundation for body skin that deserves the same attention we give the face.
