En quoi la peau sèche est un symptôme de déshydratation et comment l'atténuer ?

How is dry skin a symptom of dehydration and how can you reduce it?

The skin is our largest organ. Its role is to defend us against external aggressions , but also to regulate body temperature and prevent excessive water loss . A common problem is dry skin , which can be a sign of dehydration in the body. In this article, we'll explore the causes of dry skin related to dehydration and our tips for preventing dry skin.

Understanding the skin and its water supply

The skin is made up of three main layers: the epidermis , the dermis and the hypodermis . Each of these layers serves to preserve hydration and helps protect the skin.

The layers of the skin

The epidermis is the outermost layer of the skin, responsible for protection against external aggressions and moisture retention. It is composed mainly of keratinocytes, cells that produce keratin, a protein that strengthens the skin.

The dermis, located under the epidermis, contains collagen and elastin fibers which ensure the suppleness and elasticity of the skin. Present in the dermis, hyaluronic acid participates in water retention and contributes to the hydration and firmness of the skin.

The hypodermis , the deepest layer of the skin, is composed primarily of fatty tissue. It ensures thermoregulation and protection of internal organs. This layer also contains energy reserves and contributes to the suppleness of the skin.

Skin hydration mechanisms

To understand how to improve skin hydration , it is essential to know the internal mechanisms that regulate it. Dry skin is characterized by a lack of water in the outer layer, leading to redness , irritation and tightness .

The importance of water for the skin

Water is a necessary element for maintaining the health and beauty of the skin, it is decisive for the structure and function of skin cells, such as keratinocytes and fibroblasts, responsible for the production of collagen and elastin. A good water intake is necessary to maintain the firmness and elasticity of the skin . When the skin is well hydrated, it appears more supple , smooth and radiant , thus avoiding dryness and irritation. Hydrating products, such as moisturizers, help retain water in the upper layers of the skin, contributing to its plump, smooth appearance. By adequately hydrating the skin, we also strengthen the lipid barrier , composed of ceramides and fatty acids, essential to limit water loss by evaporation and defend against external aggressions . A strong lipid barrier is fundamental to preventing skin dryness and maintaining healthy, protected skin. Water helps transport nutrients and oxygen to skin cells, supporting the process of cellular regeneration and the production of collagen and elastin. Therefore, moisturizing dry skin helps strengthen its structure and reduce the visible signs of aging.

The impact of dehydration

Dehydration has detrimental effects on the skin, altering its structure and functions. Dehydrated skin suffers from a weakened skin barrier, leading to increased water loss through evaporation and decreased hydration of the upper layers. This makes the skin dry, dull and prone to irritation. Excessive water loss also alters the extracellular matrix, reducing the production of collagen and elastin , leading to the formation of fine lines and wrinkles . Dehydration also compromises the function of the lipid barrier, increasing the permeability of the skin and making it more vulnerable to external aggressions . Additionally, it can disrupt the balance of the skin microbiota, worsening skin problems such as inflammation and sensitivity. A good water intake helps maintain a strong lipid barrier, thus preventing skin dryness and contributing to healthy, well-protected skin. It is therefore essential to recognize the symptoms of dehydrated skin and act quickly to prevent further damage. Using appropriate care and regularly hydrating the skin with moisturizing products helps restore and maintain the hydration necessary for glowing, healthy skin.

Our hydration tips for the skin

Hydration plays a crucial role in maintaining the health and beauty of the skin. Here are some of the main benefits of hydration for the skin:

Have a skincare routine

To prevent dry skin, avoid products containing alcohol, sulfates, artificial fragrances and dyes. These ingredients can strip the skin's natural oils, leading to increased dryness and irritation. Opt for gentle and hydrating products, without these harsh components.

Adopt healthy habits

Drink enough water: Proper hydration starts from the inside out. In fact, drinking enough water helps prevent water deficiency in the skin.

Suitable cosmetic creams: Recognize dry skin and act quickly with suitable cosmetic products such as creams or oily treatments, oils to nourish the skin and prevent more serious problems.

A moisturizer: Using a rich moisturizer helps lock in moisture and prevent dry skin.

Gentle cleansing: To treat dry skin, you need to use specific moisturizing products and clean your skin with gentle cleansers. Avoid those containing alcohol and other drying ingredients. Factors like cold and wind can dehydrate the skin, so recognizing dry skin and acting quickly is crucial.

Rich and nourishing products: In winter, the cold can worsen dry skin. So we advise you to use richer and nourishing products to strengthen your skincare routine. This can improve the appearance of the skin and prevent long-term problems.

The effect of Hydratis lozenges on the skin

Hydratis lozenges are specially formulated to improve body hydration and, therefore, that of the skin. The zinc contained in the lozenges plays a role in many biological functions, from inflammation to the regulation of sebum secretion. It has anti-inflammatory properties that help reduce redness , irritation , and skin blemishes . Zinc also stimulates the production of collagen , which is essential for repairing damaged tissues and preventing unwanted scarring . In addition, its antioxidant properties protect the skin against damage caused by free radicals, responsible for premature aging and cellular damage.

In summary, dry skin is often a sign of dehydration in the body. Understanding the skin's rehydration mechanisms as well as the factors that contribute to dryness is important to protect the skin. So moisturize well to make your skin healthy and glowing . The lozenges offer you an effective solution to improve your body hydration and that of the skin thanks to their formula based on carefully selected ingredients such as minerals and trace elements.
