Preparation for Use
Before First Use:
Ensure your eyelids are clean, dry, and free of any oils or other makeup residues before applying the eye base. This provides the best canvas for optimal product performance.
Skin Compatibility:
This product is suitable for all skin types. If you have sensitive skin, it is recommended to perform a patch test on a small, inconspicuous area of skin before full application.
Application Guide
Step 1: Dispense Product
Squeeze a very small amount of the Prep Plus Prime 24-Hour Extend Eye Base onto your fingertip. A pea-sized amount is typically sufficient for both eyelids.

Step 2: Apply to Eyelids
Gently dab and blend the product evenly over your entire eyelid, from the lash line up to the brow bone. You may use your fingertips or a clean eyeshadow brush for application.
Step 3: Allow to Dry
Allow the eye base to dry completely for a few seconds before proceeding with your eyeshadow application. This ensures the primer sets properly and creates an optimal surface.
Step 4: Apply Eyeshadow
Once the primer is dry, apply your desired eyeshadows as usual. The base will help colors appear more vibrant and blend more smoothly. Use minimal product for a natural look, or build up for more intense color payoff.
Optional Use:
The Prep Plus Prime 24-Hour Extend Eye Base can also be worn alone as a subtle, perfecting base for your eyelids.
Care and Storage
To maintain the quality and efficacy of your MAC Prep Plus Prime 24-Hour Extend Eye Base, please follow these guidelines:
- Store the product in a cool, dry place, away from direct sunlight and extreme temperatures.
- Ensure the cap is tightly closed after each use to prevent the product from drying out or becoming contaminated.
- Avoid introducing water or other substances into the product container.
Troubleshooting Common Issues
Issue: Eyeshadow Creasing or Fading
If you experience eyeshadow creasing or fading, ensure you are applying a thin, even layer of the Prep Plus Prime 24-Hour Extend Eye Base. It is crucial to allow the primer to dry completely before applying any eyeshadow. Applying too much product or not allowing it to dry can hinder its performance.
Issue: Uneven Eyeshadow Application
The eye base is designed to create a smooth surface for eyeshadow. If your eyeshadow appears uneven, check that the primer was blended uniformly across the entire eyelid. Re-application of the primer may be necessary if the surface is not smooth.
