MAC Prep + Prime 24-Hour Extend Eye Base Primer 0.4 oz — Lightweight, Long-Wear Color-Boosting Eye Primer

MAC Prep Plus Prime 24-Hour Extend Eye Base is a lightweight eyelid primer that smooths skin and keeps eyeshadow vivid and crease-free for up to 24 hours.

Whether you need reliable wear for a long workday, event, or photoshoot, this MAC eye base creates an even, non-tacky canvas that intensifies color while minimizing creasing and migration. The subtle, weightless texture blends easily across lids and works under powders and creams, helping makeup retain its original finish from morning to night.

How does this primer keep eyeshadow looking fresh all day?

The formula grips pigment and reduces oil-related movement on the eyelid, so shadow stays where you place it instead of settling into fine lines. It creates a smooth surface that prevents color break-up and keeps shade payoff true for extended wear.

• 24-hour hold that reduces fading and smudging.
• Oil-control properties help prevent shadow migration.
• Creates a smooth, even base for blending and layering.

Will this work with my skin type and makeup routine?

Yes—MAC designed the eye base to suit a wide range of skin tones and textures. Its lightweight, non-sticky feel layers well beneath powder or cream eyeshadows and won’t pill when you blend or build intensity.

• Suitable for dry, normal, combination, and oily eyelids.
• Compatible with both powder and cream eyeshadows.
• Non-greasy finish that won’t interfere with setting products.

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

Apply a small amount across the entire lid and blend evenly with a fingertip or brush, concentrating on areas prone to creasing. Allow a few seconds for the primer to set before applying eyeshadow to ensure optimal adhesion and color payoff.

• Use a pea-sized amount for both lids; less is more.
• Blend outward to avoid excess product buildup in folds.
• Wait briefly before layering eyeshadow to lock pigment in place.

What difference does this primer make for color and finish?

This eye base enhances the saturation of eyeshadow, making hues appear truer and more vibrant than without a primer. It also helps maintain the intended finish—matte shades stay matte and shimmers retain their payoff—while preventing patchiness over time.

• Amplifies pigment for richer, bolder color.
• Preserves matte and shimmer textures over long wear.
• Prevents uneven fading and blotchy appearance.

Who this is for: MAC Prep Plus Prime 24-Hour Extend Eye Base is ideal for anyone who needs durable, color-enhancing eye makeup—makeup artists, event attendees, or daily wearers who want pigment longevity and crease control. It’s especially useful for oily lids, mature skin prone to creasing, and anyone seeking truer color payoff throughout the day and night. The 0.4 oz size fits easily into a makeup kit or travel bag for dependable long-wear performance wherever you go.
