Dehydrated skin occurs when the skin lacks sufficient water, a condition that can affect individuals of any skin type, including those with oily or combination skin. The characteristic signs of dehydrated skin include a dull complexion and the manifestation of premature aging indicators such as surface wrinkles and diminished elasticity. On the other hand, dry skin is a distinct skin type, akin to oily or combination skin, where the issue is a deficiency of oils or lipids, resulting in a flaky and dry appearance. Dry skin may also present with a scaly texture, white flakes, redness, irritation, and an increased likelihood of conditions such as psoriasis, eczema, or dermatitis.
