Dry skin is characterized by a deficiency of natural oils, making it distinct from oily skin. When your skin lacks sufficient oil, it can appear lackluster and feel tight. In more severe cases, dry skin may lead to cracking, flaking, or peeling. It's important to note that dry skin and dehydrated skin are terms sometimes used interchangeably, but they refer to different conditions. Dry skin is primarily about the lack of oil, while dehydration is related to insufficient water content in the skin, a concern that can affect individuals regardless of their skin type.
