Dry skin is not the same thing as dehydrated skin. While they have similar qualities,
they have different underlying causes. Dry skin results from inadequate levels of
oils (lipids) deposited on the surface from the sebaceous glands, while dehydration
results from a lack of water in the skin.
Dry Skin, as a skin type or inherited trait, has small pores and
may be stiff or even flaky, causing less oil to be deposited on the surface of the
epidermis. Dry skin as a skin condition can occur in any skin type and is caused
by irritants such as sun exposure, harsh cleansers, and other factors such as wind
and pollution. Dry skin has an easily irritated, possibly flaking surface and seeks
surface moisturisation. Dry skin is treated with non-comedogenic oils on the skin
surface.
Dehydrated Skin, as a skin condition, has less water than normal
skin. This can occur through moisture evaporation, excessive transepidermal water
loss, and environmental exposure. Examples of environmental factors include wind,
which can pull hydration from the skin, and long showers or other activities characterized
by prolonged exposure to water. Over-cleansing, use of certain medications, and
application of the wrong skincare products can also cause dehydration. Dehydration
can affect any skin type, including skin with either large or small pores. Tiny,
crepe-like, triangular fine surface lines that can be seen through the magnifying
light indicate dehydrated skin.
Correctly assessing the condition of the skin as dry, dehydrated, or both, is important
to choosing the right products.
