Q: Why does skin become dehydrated? A: Wind, extreme temperatures, sunlight exposure, air conditioning, use of harsh cleaning products, skin aging ... The water loss is accelerating.
The skin
becomes uncomfortable and feels tight in some areas, it is rough to the touch,
dull and fine dehydration lines appear.
DRYNESS AND
DEHYDRATION
About 60% of
the entire human body, including the dermis, is made up of water. This is not
the case for the epidermis, which has a surface layer acting as an interface
between the very humid inner environment and the outside air which is much
drier. The epidermis contains 20 to 30% water and its outermost layer, the
stratum corneum, contains 10 to 20%. This stratum corneum has a particular
structure, often compared to a wall made of bricks (the corneocytes) and cement
(the intercellular lipids), which prevents water from evaporating from the
body.
What is
dehydrated skin?
Whether you
have naturally dry, combination, normal or oily skin, it can become dehydrated
by environmental aggression.
Skin type
Certain types
of skin are naturally better hydrated or less dry than others. Dry skin,
whether simple xeroses, xeroses from atopic dermatitis, or ichthyosis, contains
much less water than normal skin. This dryness is caused by irregularities in
lipid (ceramides) or protein metabolism (proteases, filaggrin) or even by
epidermal differentiation problems.
“Ordinary” dry skin:
Simple
xeroses are the most common. These are easily corrected by applying emollients.
Senile
xerosis: is more pronounced on the limbs.
Winter
xerosis occurs when simple xerosis is intensified with cold and wind.
Induced
xerosis refers to skin dehydrated by cleansing products that contain overly
harsh surfactants (soaps). In the same way, irritant treatments (retinoids,
fruit acid) dry out the skin.
Dry skin
disorders:
Atopic
xerosis: atopic dermatitis or infantile eczema includes dryness of the skin
that is more or less intense. Linked to structural irregularities in the
epidermis, this type of dryness is responsible for the penetration of allergens
and for water loss through the epidermis.
Ichthyoses:
these are rare genetic or acquired diseases, with varying severity
Some severe
nutritional deficiencies can provoke or worsen dryness of the skin.
Some general
diseases can cause the skin to become dry.
