Will drinking more water fix dry or breakout-prone skin?

Not directly. If you are adequately hydrated, drinking more water does not measurably change skin hydration or clear breakouts — the body regulates fluid balance long before it reaches your face. Dehydrated-feeling skin is usually about barrier function and the environment, which is a topical and lifestyle problem rather than a drinking one.

What the body does with extra water

Fluid balance is tightly regulated. In someone already adequately hydrated, additional water is largely excreted rather than routed to the skin. This is why the advice so rarely produces the promised result.

Dehydration in skin is a barrier issue

Skin that feels tight and looks crepey is usually losing water to the air faster than it can hold it — a barrier and environment problem. Humectants, occlusives and humidity address it; a larger water bottle does not.

Where hydration genuinely matters

Actual dehydration does affect skin, along with everything else. If you are unwell, exercising hard or in extreme heat, drinking properly matters. That is a different situation from adding litres to an already adequate intake.

What to do instead

Use a humectant on damp skin, seal it with a moisturiser, and consider a humidifier if your air is dry — Korean winters and air conditioning are both notorious for this. Those steps do what the water myth promises.
