MAC Prep + Prime 24-Hour Extend Eye Base Primer 0.4 oz — lightweight, crease-free color boost

MAC Prep Plus Prime 24-Hour Extend Eye Base is a lightweight eyeshadow primer that smooths lids and helps eyeshadow stay crease-free and vibrant for up to 24 hours.

Designed to create a clean, even canvas on eyelids, this primer from MAC enhances pigment payoff and extends the life of powder and cream eyeshadows. The weightless formula minimizes creasing and smudging while remaining comfortable to wear all day and night. Suitable for a wide range of skin tones and types, it’s formulated to intensify color and stabilize makeup for long-lasting looks.

How does this primer keep eyeshadow from creasing?

The formula smooths the lid surface and creates a slightly tacky base that eyeshadow adheres to, which reduces migration into fine lines. By evening out texture and oil on the eyelids, it prevents color from separating or settling into creases throughout the day.

• Creates a smooth, even canvas for shadow application.
• Minimizes lid oils that cause makeup breakdown.
• Leaves a subtle grip so powder and cream pigments stay in place.

Will it make my eyeshadow look more pigmented?

Yes — this eye base is formulated to amplify color payoff so shadows appear truer to pan shade and more intense on the lid. It helps both sheer and richly pigmented shadows layer evenly, so you need less product to achieve bold or blended effects.

• Boosts vibrancy for both matte and shimmer shadows.
• Helps buildable formulas reach full saturation faster.
• Maintains color integrity without dulling metallics or shimmers.

How do I apply MAC Prep Plus Prime 24-Hour Extend Eye Base for best results?

Apply a small amount across the eyelid from lash line to crease and blend gently with a fingertip, brush, or sponge applicator. Allow a few seconds to set before layering eyeshadow; a thin, even layer performs better than heavy applications.

• Use a pea-sized amount for both lids; tap and blend outward.
• Let the primer dry briefly to avoid product slipping.
• Pair with powder or cream shadows for long-lasting wear.

Is this primer suitable for sensitive or oily eyelids?

The lightweight, non-sticky texture is formulated to work across skin types, including normal, oily, and combination lids. It reduces shine and helps control oil-related fading, while remaining gentle enough for everyday use; patch-test if you have very reactive skin.

• Lightweight finish avoids heavy residue on eyelids.
• Helps control excess lid oil that shortens wear time.
• Works under cream and powder shadows without pilling.

Who is this for: Ideal for anyone who wants eyeshadow to look truer to color and last through long days, from makeup beginners to professional artists. Choose MAC Prep Plus Prime 24-Hour Extend Eye Base if you need a universal primer that strengthens pigment payoff, prevents creasing, and feels weightless on the lids — whether for everyday wear, events, or travel-ready makeup routines.
