Skin Dehydration
Skin Dehydration — a temporary lack of water in the skin, distinct from dryness, which is a lack of oil. Dehydrated skin can feel tight and look dull or show fine surface lines, and it can affect any skin type, including oily and combination skin.
Key points
- Dehydration reflects low water content in the skin, whereas dryness relates to insufficient natural oils or lipids.
- It can be triggered by weather, over-cleansing, low water intake, air conditioning, or a compromised barrier.
- Humectants such as glycerin and hyaluronic acid attract water into the upper layers to help address dehydration.
- Sealing hydration with an occlusive or emollient moisturizer helps reduce water loss from the skin surface.
