M·A·C Studio Fix Fluid Foundation SPF 15 N4 is a breathable, oil-free liquid foundation that gives buildable, longwearing coverage with a natural matte finish and sun protection.

What coverage and finish will I get with N4, and how do I build it?

Studio Fix Fluid provides buildable coverage from medium to full with a natural matte result. It blends evenly and can be sheered out or layered depending on the amount you use and the application tool. Mixing one drop with a moisturizer softens the finish, while using a dense brush or sponge increases opacity.

• Buildable medium-to-full coverage
• Natural matte finish that reduces the appearance of pores
• Mix with moisturizer or facial oil for a more luminous effect
• Apply with 130S brush or damp sponge for different levels of coverage

Does this foundation provide skin benefits beyond coverage?

Yes — the formula is oil-free and provides immediate and lasting moisture for up to eight hours, while minimizing the appearance of pores and uneven texture. It is free of many common additives like parabens and mineral oil, making it a cleaner option for daylong wear without a heavy feel.

• Immediate and up to eight hours of moisture without oiliness
• Helps smooth the look of pores and blemishes for a refined complexion
• Free from parabens, phthalates, mineral oil and other listed irritants
• Includes SPF 15 for incidental sun protection during wear

How should I apply Studio Fix Fluid for the best, most natural result?

Begin with cleansed, well-moisturized skin to ensure even spread and lasting finish. Use the M·A·C 130S Brush for a studio-polished application, a damp sponge for seamless blending, or fingertips for quick touch-ups. Adjust coverage by adding thin layers, and set with a light powder if extra oil control is needed.

• Prep skin with moisturizer and primer as desired
• Apply thin layers with 130S brush, sponge, or fingers
• Mix with moisturizer for a sheerer, dewier finish
• Set selectively with powder to extend oil control and longevity

Who is this for: M·A·C Studio Fix Fluid SPF 15 N4 suits anyone seeking reliable, buildable coverage with a natural matte look—especially people with normal to oily skin who want shine control, pore-smoothing effects and sweat-resistant wear. It's a practical choice for daily use, professional makeup, or long days when dependable color and a breathable finish are priorities.
