Dry skin needs permanent hydration due to an abnormality in the skin barrier. To remedy feelings of tightness and itching, shea butter is an excellent natural treatment. It is rich in saturated and oleic fatty acids and prides itself on regulating and retaining moisture in the skin. It wraps the skin in a greasy film that protects it from external aggressions.
Why is the skin very dry in winter?
The symptoms of dry skin depend on the person, but they often result in a feeling of tightness or even cracking. As for very dry skin, we recognize it since it shows forms of cracks, redness, or patches. Consequently, this type of skin dryness can be associated with atopic dermatitis, psoriasis, or eczema.
Namely, the factors causing this skin dryness can be linked to internal factors such as heredity, hormones or aging since the skin is thinner and produces less sebum. The external factors that can lead to dry skin can be linked to climatic conditions, limescale in the water, irritating hygiene products or drug treatments that dry out the skin.
Causes resulting from dry skin:
The superficial layer of the skin, known as the "cutaneous barrier", is covered with a hydrolipidic film which is made up of water and lipids (fat in living beings) produced by the sebaceous glands. These sebaceous glands are responsible for the synthesis and secretion of sebum which must protect the skin and prevent water from evaporating. This hydrolipidic film makes it possible to use the surface of the skin and form a protective barrier against the cold, UVA and UVB rays, bacteria, fungi, but also toxic and chemical products. This slowed production of sebum can be aggravated by an unhealthy lifestyle (alcohol, tobacco, etc.). It is important to counteract this trans-epidermal loss of water by hydrating the skin.
What are the benefits of Shea Butter?
To maintain your skin, you must moisturize it morning and evening and use richer products to compensate for this dryness. You should avoid lotions, exfoliants, scrubs or even the sauna, which will dry out the skin even more. This is why it is necessary to move towards more fluid and rich textures.
In addition, the natural lipids present in shea butter make it possible to replace the lack of cutaneous lipids. In addition to moisturizing, it is rich in vitamin A, which promotes skin elasticity and damage from the sun's rays. It also has other vitamins (E, D and F) and elements that help protect the skin from UV rays such as terpene alcohols or phytosterols. The benefits of shea butter do not stop there since it contains fatty acids such as oleic acid (omega 9) and linoleic acid (omega 6) which help strengthen the lipid cement of the skin and cover it with a moisturizing veil.
What is the specificity of the Xemose range?
The Xemose range concentrates emollient products that respond to all degrees of skin dryness. For extremely dry or even atopic skin in winter, the Lipid-Replenishing Anti-Irritation Cerat is very rich. It restores the skin barrier and regulates the microbiome thanks to Uriage’s Thermal Water. This cerat contains 25% shea butter and immediately soothes itching sensations that cause scratching. For skin that is dry in winter, the Anti-Itch Soothing Oil Balm or the Lipid-Replenishing Anti-Irritation Cream will do just fine. There is also shea butter, but in smaller quantities because the dryness is less visible.
