Stevo,, just like dontdrinkurmilk said.. start drinking more water each day. Now that it's summer you should drink even more than the regular 8 glasses per day to compensate the extra loss of water.
Also, try to help your complexion by applying some facial masks on it. Natural face masks.
The quickest one is plain yogurt. It will nourish your skin, it is anti-inflammatory, cools down and soothes the skin.
Just take plain natural yogurt, doesn't care how much fat it has, and using a foundation brush (or your fingers_ apply it on your entire face. Leave it on for 15 - 20 minutes then rinse off with warm water.
You can do this every day or every other day, in the evening. Just make sure you are not allergic to yogurt. You can try it on a smaller patch first, but I doubt you will have any bad reactions to it.
Another one would be green te face mask. Aside from drinking it, you can soak a paper tissue in green tea and then apply it on your face. You can make an entire mask out of a tissue (cut out the holes for eyes, nose and water), dip it in green tea and then let it sit on your face for 20 minutes.
Lots of benefits from this
