Illuminating primers typically provide a radiant, dewy or luminous finish. Many formulas include light‑reflecting pigments or fine micro‑shimmer to create a subtle glow without obvious sparkle.
Primers are marketed for a wide range of skin types—commonly normal, oily, dry, and combination—and many listings also call out suitability for mature, sensitive, very dry, or acne‑prone skin depending on the formula.
They typically smooth and blur texture, help makeup adhere and last longer, and add radiance or a dewy finish—creating a more even, luminous base.

Hydrating primers often list hyaluronic acid, vegan collagen, or other hydrating extracts; blurring primers rely on smoothing agents and light‑reflecting or blur pigments that minimize the appearance of pores and imperfections.
