Dehydrated skin is the type of skin that lacks water specifically. This means the skin is lacking hydration or moisture, which can be caused by factors like weather, diet, using harsh skincare products, or not drinking enough water.

Combination skin refers to having a mix of dry or normal skin with oily areas, so it is not specifically lacking water like dehydrated skin. Dry skin lacks oil or sebum production, not necessarily water. Oily skin produces excess oil, but this does not mean it lacks water.
