I use a foundation brush to apply my foundation then use a round blusher brush to blend it in using a swirling motion giving a flawless look.
another good tool to use is the BEAUTY BLENDER which you wet and squeeze making it fluffy. this presses the makeup in to your skin and blends it beautifully. put the foundation on the back of your hand as you have heat in your hand when you press the foundation into your hand with the sponge you are warming it up and breaking it up before it goes directly on to the skin. set your foundation with loose powder using a puff dab the puff on to your hand so that you don't get a blob of powder on your face.
