What's the difference between a dewy and a matte foundation?

Dewy or luminous foundations leave a radiant, slightly reflective finish that mimics healthy, hydrated skin, while matte foundations control shine for a flatter, more velvety look. Several products in this pool (notably the IT Cosmetics Natural Matte and Lancôme Teint Idole Naty Matte lines) are matte formulas and sit outside the dewy category, so we prioritized the genuinely luminous options.
