Next: weather. Summer heat or a dry office with the AC blasting will steal moisture from your skin like a thief. You have to pay that back.

And for the love of all that is holy, don’t chug a gallon just because some influencer told you to. That’s a fast track to a bathroom marathon and a headache.
