Dry skin lacks oil
Dry skin produces less sebum than average. It tends to feel rough, look matte all day and show fine flaking, especially on the cheeks.
Dehydrated skin lacks water
Any skin type can be dehydrated, including oily skin. It often looks dull, shows fine lines that come and go, and can feel tight while still getting shiny by midday.
A quick check
Gently pinch the skin on your cheek. If it creases into fine lines and takes a moment to bounce back, it is likely short on water. Humectants like amino acids, PCA and urea help with that. Dry skin also needs richer, oil-based moisture on top.
