thx on your advice. for people like me, i work a lot under sunshine. most of the time i wont bother to apply any skincare product onto my skin incl face. sometime i got sunburn. and i realize, when i work in the office with nice air-cond, my face became really oily. when that happen, i usually wash with tap water and apply dry towel. several hours later, it became oily again. 

for a guy like me, do you have any product/brand to recommend?
