How to apply make up that would look natural?

You are right. people who are apt at making up make their face look natural, hardly find the trace of make up. I've learned a little about it when I worked at Avon company. Let's take eyeshadow for example. The simplest way is to buy a colors in 1 eyeshadow compact. the colors are picked up belonging to the same hue. First rub the lightest color on the whole eyelid to make our skin like a painting paper, then apply the darkest to the upper eyeline, it can be rough and not very thin line because it will soon be covered by the next color. Last the lighter strecth above the dark. Done ! better use wool brush. All these colors are mixed naturally like a whole due to their same color hue. Happy try.
