First, a little science—don’t worry, it’s easy. Dehydration means your body lacks water overall. Dryness means your skin lacks oil. You can be dehydrated even if your skin feels greasy.
When you’re dehydrated, your skin’s barrier gets weak. It can’t hold onto moisture, so it gets irritated, red, and prone to breakouts. A glass of water helps reinforce that barrier from the inside out.
But here’s where it gets interesting: drinking water won’t magically unclog pores. That job belongs to your skincare routine, not your water bottle.
