mascara primer

Apply primer from the base of the lashes to the tips with the wand, coating evenly. Allow the primer to dry or set—typically about 30–60 seconds depending on the formula—before layering your mascara.

Most mascara primers come in small tubes; net weights commonly range around 0.23–0.44 fl oz. Many brands also offer trial, mini, or travel-sized options or small tubes suitable for travel.

Formats include double-ended or built-in systems with a primer on one end and mascara on the other, and single-tube 2-in-1 formulas that contain both a visible primer side and the mascara in one package.

Primers help mascara adhere to lashes, extend wear time, reduce smudging and fallout, and improve overall hold so mascara is more likely to last through the day.
