What is Dehydration?

A lack of water in the skin independent of oil levels — a concept distinct from dry skin type

Even oily skin can be dehydrated (oily-dehydrated). This is a state of increased transepidermal water loss (TEWL).

Main causes & characteristics

A condition in which the skin lacks moisture independently of oil levels, meaning it can occur even in oily skin types (dehydrated-oily skin). When cold air, indoor heating, excessive cleansing, or a weakened skin barrier increases transepidermal water loss (TEWL), the skin is known to develop a parched, tight feeling from within.

How to manage

It is generally recommended to replenish moisture with humectant ingredients such as hyaluronic acid, glycerin, and panthenol, then seal it in with oils or ceramides to prevent evaporation. Cleansing briefly with lukewarm water and reducing excessive exfoliation may also help. If tightness persists for an extended period, consulting a dermatologist is recommended.

Good to know alongside

This condition is often discussed alongside dehydrated-oily skin (oily yet moisture-deficient skin), barrier impairment, and transepidermal water loss (TEWL).

Everyday care tips

Moisturizing before flakiness appears is key — applying a hydrating product while the skin is still slightly damp immediately after cleansing is a habit known to help retain moisture effectively.
