Start the process by cleansing and moisturizing your skin so that the liquid blush has a proper base to stay on. While the use of a primer is optional, it does make application even smoother and allows moisture to seep into the skin, creating a tight layer for the blush. Next, take some blush on the tip of your finger and begin dabbing it gently along the apples of your cheeks for a subtle and sheer effect. You can also use a brush to blend the product well and make it look as natural as possible.
