Dewy looks have been popular in summer. They give your skin a healthy glow and makes your skin look healthy. If you have acne, then I would recommend you this because glowy/dewy skin hides acne imperfections.
The primer will create a barrier between your skin and liquid shadow. Then very lightly dab the liquid shadow on the cheek bones to give a glow. You can also apply to the outer part of your face. Just follow the face chart in the picture shown.
You can also use shimmery powder shadow but it won’t give you the dewy look. So I like the liquid one better.
