Definition: Type of skin with impaired cellular cohesion, a deficiency in natural moisturizing factors (NMF) and a deficiency in the production of fatty substances. This lack of hydrolipidic film exposes the epidermis to external aggressions and causes water loss. It presents as tightness, a tight skin texture, feelings of discomfort, a "crocodile skin" effect, skin flakes, tingling, a lack of suppleness, redness, irritation, cracks, a dullness, and thin, rough skin.
Internal and external causes: Heredity, climatic changes, overly aggressive skincare, certain medical treatments (anti-cholesterol), certain skin pathologies and general illnesses (eczema, nutritional deficiencies, psoriasis, etc.)
How to reduce or eliminate them: Use products enriched with lipid-replenishing and occlusive agents (ceramides, squalane, plant oils, plant butters, plant waxes, etc.).
Preventive measures: Drink enough water (1.5 litres per day); choose non-aggressive products; avoid overheated environments; pat your face dry without rubbing; simply use a lotion or a hydrolate in the morning during the cleansing stage.
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.
