Dry skin

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: Use products enriched with lipid-replenishing and occlusive agents (ceramides, squalane, plant oils, plant butters, plant waxes, etc.).

Preventative steps to take: 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.
