Apply a generous amount of blush on your brush and swirl it around (for about 3 seconds) on the palm of your hand, then apply the blush on the cheeks with your brush. Continue this until you get the desired amount on the cheeks.
This tip will distribute the perfect amount of product so it does not look or feel too heavy and will reduce the risk of having uneven and blotchy blush on.
This tip does not only work on blushes but it is definitely my favorite tip for blush. Try this tip for your bronzer and eyeshadows as well.
