Definition: Recurring but punctual and reversible phenomenon, corresponding to a failure of the hydrolipidic barrier which is no longer able to retain water. It manifests itself by a loss of radiance and comfort that translates into a feeling of tightness, particularly after cleansing or showering. All skin types can experience episodes of dehydration.
Internal and external causes: Environmental factors (cold, wind, pollution, sun, etc...), stress, fatigue, smoking, insufficient hydration, alcohol consumption, use of cosmetic products that are too aggressive / stripping, taking certain medications (anti-cholesterol, anti-acne, etc...), menopause, skin aging.
How to reduce or eliminate them: Use formulas rich in humectant and emollient ingredients (glycerin, urea, polyglutamic acid, hyaluronic acid, aloe vera, etc.).
Preventive measures: Drink at least 1.5 liters of water every day; avoid overheated or air-conditioned rooms; choose non-aggressive skin care products; apply a moisturizer day and night; protect yourself from UV rays; favor gentle care products; remember to properly clean and remove your face at night.
In addition to typically being dull, dehydrated and dry skin is also rough to the touch and shows signs of flaking. This type of skin affects all skin tones and almost all age groups. Fortunately, the use of a moisturizer for dehydrated skin can restore softness and suppleness.
