Obsessed with makeup tutorials

I've been really hooked on watching youtube videos lately regarding make-up application. I'm not a make-up guru and the reason why i was watching videos a lot is because i want to learn at least the chorder of the guru's knowledge. I personally like to learn the tips regarding how to remove dark circles under eyes or at least hide it using the concealers because i know for a fact that my main problem are the eyebags which has been in the area forever. I never use any eye cream because i really don't know what product should be getting. Another reason i want to learn with make ups is the basic of applying foundation in a skin to look fresh and natural. So far, i learn a ways and the only thing that i wanted now is to buy good makeup products since i only have limited products in my kit.
