Flakiness on the skin is often an indicator of dehydration. Dehydrated skin lacks moisture, which can lead to a rough texture and the formation of dry, flaky patches. When the skin is not receiving enough hydration, it struggles to maintain its natural barrier function, resulting in a compromised surface that can flake off.

While excessive oiliness typically manifests as a shiny or greasy appearance, and aging signs might lead to changes in texture or elasticity, flakiness specifically points to a deficiency in moisture rather than oil. Sunburn can indeed cause peeling skin, but this effect is usually more pronounced after the skin has been damaged by UV exposure, rather than indicating a chronic condition of dryness. Therefore, the most accurate interpretation of flakiness is that it signifies dehydration.
