What's the difference between a dewy and a matte setting spray?

Dewy or luminous sprays (like the e.l.f. Power Grip Dewy and Urban Decay's Glass-Skin Glow formula) add a hydrated, reflective finish and tend to suit normal-to-dry skin. Matte formulas (like Urban Decay All Nighter Matte) blur shine and help control oil, which verified-purchase reviewers generally prefer for oily or combination skin.
