How to make your foundation last longer

The most important trick to make your foundation last longer is to have a good skin as a canvas. Don't get me wrong, I'm not saying that if you have scars or acne your skin isn't good enough to make the foundation last. But, just like the painters choose a good & clean canvas to paint, it's the same with make up, specially the foundation.
Whether you were graced by nature to have a flawless skin or you have oily skin or acne, you need to clean your skin with a product suitable for your type;
Apply a moisturizer before the foundation, make sure your moisturizer is suitable for your skin type as well: if you have oily skin, choose an oily free product;
Applying a primer before the foundation (and after the moisturizer) is key: you will be able to keep the makeup in place through the whole day while preserving the moisture you applied before. A specific eye primer is essential as well, to keep your eye shadow and eyeliner in place;
Choose a good foundation, mineral foundation does wonders as they usually have a thin layer finish avoiding the "cakey" effect and set it with translucent powder, for a matt finish;
Before applying the lipstick or gloss, make sure your lips are moisturized as well, specially if you're wearing a long wearing product, since they are usually very drying;
Last but not least, flaunt that precious smile of yours: happiness radiates your inner shine, and that lasts even longer than foundation!
