MAC Prep Plus Prime 24-Hour Extend Eye Base Primer, 0.4 oz — Neutral Finish, Long-Wear

MAC Prep Plus Prime 24-Hour Extend Eye Base is a lightweight eyelid primer that smooths skin and locks eyeshadow in place for up to 24 hours.

Designed by MAC for long wear and color payoff, this 0.4 oz eye base creates an even surface on the eyelids to reduce creasing, fading, and smudging. Its weightless texture blends easily, intensifies pigment, and works across skin tones and types so eyeshadow stays vibrant through busy days and long evenings. The formula pairs with powder and cream shadows, offering a reliable foundation whether you’re doing a quick daytime look or extended wear for events.

How does this primer keep eyeshadow crease-free all day?

The primer forms a smooth, tack-free layer that grips product and fills fine lines so shadow sits evenly on the lid. By reducing excess oil and creating a uniform surface, it prevents pigment from migrating into creases and fading over time. You’ll notice shadows blend more predictably and maintain the intended finish throughout wear.

• Creates an even base that minimizes uneven texture and fine lines.
• Reduces oil-related breakdown of pigments for longer wear.
• Helps powder and cream shadows adhere without slipping.

Will this primer enhance my eyeshadow’s color intensity?

Yes—Prep Plus Prime 24-Hour Extend Eye Base boosts color payoff so shades appear truer to pan on the lid. The neutral finish brightens and amplifies pigments, making both subtle and bold colors look richer. This effect helps you use less product while achieving more vivid results.

• Neutral base improves contrast and true-to-pan color payoff.
• Concentrates pigment so shades read brighter and more saturated.
• Effective with both powder and cream formulas for consistent vibrancy.

How should I apply the MAC eye base for best results?

Apply a small amount across clean, dry lids and gently blend with fingertips or a thin synthetic brush until seamless. A little goes a long way—start thin and add a touch more only if needed. Let the primer set for a few seconds before layering shadow to avoid tugging and ensure maximum longevity.

• Use a pea-sized amount for both lids; spread evenly from lashline to brow bone.
• Blend with finger or brush; allow a brief dry-down before shadowing.
• Works under pencils, liquid liners, powders, and creams for secure wear.

Is this primer suitable for sensitive or oily eyelids?

The formulation is lightweight and non-sticky, making it comfortable for sensitive or oily lids without feeling heavy. It’s designed to control the issues that commonly cause creasing and fading, while being gentle enough for everyday use. If you have specific sensitivities, patch testing first is recommended.

• Light texture avoids cakiness and heavy buildup on delicate eyelid skin.
• Helps manage oil-related wear without drying out the area.
• Compatible with most skin tones and makeup routines for versatile use.

Who this is for: MAC Prep Plus Prime 24-Hour Extend Eye Base is ideal for anyone who needs dependable, long-lasting eye makeup—makeup artists, people with oily lids, event-goers, or anyone wanting stronger color payoff and crease resistance. It suits all skin tones and ages when used as a base under powder or cream eyeshadows, and it fits seamlessly into everyday beauty routines as well as professional kit bags.
