My complexion has changed since I cut down on coffee and drink more water...

I used to be a caffeine addict who drank at least three cups of Aa (Iced Americano) a day.
I heard somewhere that coffee sucks all the moisture out of you, so I made up my mind and quit drinking it for two weeks.
Instead, I often drank lukewarm teas like adzuki bean tea or rooibos tea.
For the first three days, I thought I was going to die because my head hurt and I was so sleepy...
Amazingly, after a week, my face was less swollen when I woke up in the morning.
Above all, the 'darkening' that used to get dull in the afternoon has really improved a lot!
Consider it a trick and try cutting out coffee for just one week. It's a different story when it comes to makeup.
