You have to stay hydrated, it is very important for your wealth, your skins looks amazing when you drink water, it's the best you can do to you and your body!
I must tell you that I fail a lot in going that, I simply forget to keep hydrated or if I'm thirsty I drink soft drinks with ice (specially SeveUp, so good!!) but that is so bad, I feel my skin dry, not shinning, I hate it. So to put an end to this, I get water that I love, especial brands or I get waters that have flavor, even better. Here are my go to waters from Portuguese to International brands, this are my top, I'm always accompanied by this cool drinks.
As you can see, there's no excuse for not being hydrated, you have this cool waters.
