Both dry skin and dehydrated skin are linked to a water deficiency in the skin, but the differences are in the details.
Dry skin is linked to the lack of lipids and water-holding substances in the superficial layers of the skin called Stratum corneum.
Dehydrated skin is related to the lack of water itself or a lack of water-holding substances in the deep layer of skin called Dermis.
Skin can be both dry and dehydrated at the same time, especially if there’s a lack of water intake or intoxication for example. They’re often seen together due to stress, urban life, air pollution and UV damage.
How can you tell the difference? Look out for these key signs:
SIGNS OF DRY SKIN
— Feels irritated, dry, too tight.
— Sometimes itchy and flaky.
— Small superficial wrinkles called crinkles that look like a web can appear.
SIGNS OF DEHYDRATED SKIN
— Looks dull and tired.
— Lack of colour.
— Lack of elasticity and tightness.
— Deep and long wrinkles can form easily.
HOW TO HELP DRY SKIN
Compensate with lipid-based ‘rich’ creams and emulsions containing oils that create a coating or film on the surface of skin.
Along with water-holding ingredient friends: glycerine, hyaluronic acid, carrageenan, urea, lactic acid, mineral salts.
HOW TO HELP DEHYDRATED SKIN
Be sure to drink enough water daily. Dehydrated skin is often related to overall body dehydration, as your skin will give up its supply to other organs if there isn’t enough.
Use lightweight water-based formulations. Short and mid-chained hyaluronic acid, antioxidants, and vitamins to hydrate deep layers of skin.
