What is
dry skin?
Dry skin is classified as lipid dry, which
means it doesn't produce enough sebum, or oil. Because skin relies on oil to
hold moisture in, without it, skin can appear rough and flaky — and wrinkles
are more pronounced. Dry skin can also lead to a damaged barrier function,
increasing long term sensitivity and inflammation, and causing a chain or
biochemical reactions like collagen breakdown.
Treat dry
skin right by using moisturisers that contain emollients to provide a protective
layer that prevents moisture loss. Look for formulas that contain ceramides,
shea butter, beeswax, squalene, and oils such as jojoba oil, sunflower seed
oil, vitamin E, oil of evening primrose, argon oil, Yarrow oil calendula oil or
tomato seed oil.
Wash
with mild cleansing lotions and avoid bar soap or harsh foaming cleansers. Use
gentle exfoliators: either acids or scrubs with gentle micro beads. Exfoliating
helps remove surface flakiness and promote cell renewal, as they improve
natural production of intercellular lipids for the barrier function. I also
always recommend using a humidifier in the winter months to keep moisture in
the air, and, more importantly, in your skin.
What is
dehydrated skin?
Dehydrated skin, as a skin condition, lacks
water content, but may still produce oil. While it may be genetic or
environmental, dehydrated skin can feel flaky and tight, and often forms fine
lines easily due to the surface-cell deflation. Dehydrated skin may also be
prone flakiness, fine crepy lines on the surface of the skin and or a dull
complexion
Treat dehydrated skin by using a moisturiser
and serum that contains humectants like glycerine or hyaluronic acid, as these
ingredients attract water from the environment into the skin to keep it soft
and supple. Be gentle with skin exfoliators: Using too many acids or scrubs can
make dehydration worse, resulting in skin inflammation. Cleanse with a sulphate-free
gel to prevent unnecessary dehydration after washing.
A simple
analogy is that a leather saddle needs to be conditioned regularly with oil to
prevent it from drying out; if you were to apply water to a dry leather saddle
you would only dry it out and make it look “dried out”. Dehydrated skin produces
oil, but still feels tight, whereas dry skin produces little to no oil and can
be flaky.
