Hydrabio - Dehydrated, sensitive skin

Dry skin and dehydrated skin are often confused as the symptoms are usually very similar, if not identical: dull, uneven complexion, feelings of discomfort, tightness, tingling, irritation, and sometimes itching, as well as peeling. However, the biological causes of dry skin and dehydrated skin are very different. Dry skin is a permanent skin type that lacks water and lipids. Dehydrated skin is a state that only lacks water, but not lipids. It can affect all skin types – normal, oily, dry or combination – at any age. It is often a transient condition triggered by specific circumstances such as internal or external triggers that may disrupt the skin's biological water cycle. 

Water is essential for any living organism, and it represents about 70% of the skin’s total weight. Water is involved in many biological processes, including supporting the skin’s microbiome. A diverse microbiome is vital for skin health, and water is essential for its optimal function. Skin hydration depends on water circulating via tiny channels called aquaporins, and on the quality of the hydrolipidic film that protects the skin's surface and prevents excessive water loss. When these different flows function correctly, the skin remains hydrated and can act as an effective barrier against stressors. It is supple, soft, comfortable and radiant. When skin is overburdened by external and physiological stimuli, the consequences are often immediate, starting with a lack of radiance, followed by discomfort, tightness, tingling and peeling. 

Skin dehydration can have many causes, both external and biological. External causes of skin dehydration can include a change in your environment such as temperature or humidity, exposure to sun, pollution, or even physical activity. Biological factors like stress and fatigue can also induce temporary dehydration which can result in consequences such as a weakened barrier function, excessive water loss, dehydrated skin, and loss of radiance.

Dehydrated skin requires moisturizing ingredients. Notably, hyaluronic acid is very effective at restoring skin hydration. It can retain up to 1000x its weight in water. BIODERMA’s Hydrabio range features a specific and innovative Aquagenium technology that retains and boosts water flow, relaunching the skin’s natural hydrating mechanism. 

Start by eliminating soaps and cleansers containing aggressive surfactants that could damage the hydrolipidic film. Ideal for cleansing and removing makeup, HYDRABIO H2O MICELLAR WATER hydrates the skin right from the cleansing step. It contains gentle surfactants that perfectly and gently cleanse the skin while reactivating the skin’s natural moisturizing capacities with the patented Aquagenium technology. Next step? Apply a hydrating serum with highly concentrated active ingredients to hydrate the skin deeply and prepare your skin to receive skincare. You can then choose a skincare product suited to your hydration needs and preferences. For example, HYDRABIO GEL-CREAM is best for normal to combination skin and has a fresh, light texture. 

Even oily skin can get dehydrated because of external factors. Dehydration is a skin state that can affect all skin types including oily skin. Applying non-comedogenic moisturizer helps compensate to restore the skin's water balance, leaving it soft and supple. BIODERMA’s Hydrabio range is ideal for deeply moisturizing the skin – without overloading the skin with lipids. For oily and combination skin, favor the use of HYDRABIO GEL CREAM with its light texture, perfectly adapted to this skin type.
