Without getting into specific color matching, pairing and color theory. This is a very basic step-by-step to help guide you on how to apply blush.
There are a few ways you can approach this. I highly recommended applying foundation first, then contour, then blush, then hilighter, then powder.
Using a blush brush, apply blush on the cheekbone, the apples of the cheeks and you can even apply it to the temples.
It doesn’t matter if you sweep it, or use in circular motions. Whatever is most comfortable to you. I personally prefer sweeping it from the cheekbone upward towards the temple.
If your blush is grabbing on your foundation, and too hard to blend, you could also apply foundation, powder, powder contour, blush, then highlighter.
Either way you choose, if you’re unable to blend your blush and it’s grabbing too much, you can use a large powder brush with a translucent setting or HD powder to absorb any moisture it’s grabbing onto.
Here’s the finished look. What do you think? Now it’s your turn.
