Now that you've identified what you need, how do you put it on so your skin can look its best? First, start with the right tools:

Disposable synthetic cosmetic sponges, either triangle wedges or flat rounds Cotton swabs 3/8 inch or 1/2 inch wide synthetic bristle makeup brush (can be found at any art supply store) Large powder brush (cheap or expensive - it doesn't matter) for loose powder or sheer application of powder foundation MOST IMPORTANT: very clean hands!

You are now ready to apply your foundation. If you are using a liquid, there are a number of different techniques to actually get the foundation on your face, but I like this one because it's easy, you don't use too much foundation, and it's sanitary.

Take one of your cotton swabs, dip the end into the bottle once, remove it from the bottle and let the excess drain off, then use the swab like a crayon to draw a thin line of foundation across each cheek (like a zigzag), across your forehead, down the center of your nose, and across your chin. Now, take one of the sponges and smooth each line in downward strokes to blend. Use a gentle touch so you are blending, not rubbing it off.

If you come to a spot on your face that requires more attention, like a dark spot or blemish, use one of the makeup brushes to apply a very thin layer of foundation over the spot, then blend very gently with a clean finger or the sponge. You can also use a creamy concealer on the spot in the same way, using a brush and blending.

After you've covered everything you need to, follow up with a light dusting of loose powder to set your foundation. Whether you use a puff, a brush, or a sponge, make sure you dust off any excess so your skin looks smooth, not chalky.

If you've chosen a cream-to-powder or powder foundation, simply use the enclosed puff or sponge to apply. Swipe the sponge or puff across the foundation, and gently smooth on your face in downward strokes. Cover your face with one even layer, then add another layer if you need more coverage.

You're done! Remember, always start with less foundation than you think you need. Adding more if you need to is much easier than trying to remove too much.
