My friend noticed that our faces have become oily these past few months and she told me that stress and lack of sleep causes oiliness. And I know that also triggers pimples.

I tried researching but a lot had usage of certain products that either expensive or not available in my country. So I want to ask you guys if you know natural ways of preventing an oily face (I saw one article about eating bananas) as well as avoiding pimples.

BE MY LIFE SAVER BEFORE I DESTROY MY FAGLY FACE!!!!

[EDIT] OH MY GOD! THE COMMENTS SO FAR SAID THEY CAN'T HELP ME!!!! PLEASE I HOPE SOMEONE WHO KNOWS ABOUT THESE THINGS HELP ME
