M·A·C Studio Fix Fluid SPF 15 in shade C8 is a long-wearing, buildable liquid foundation that delivers hydrated, natural-matte coverage with broad-spectrum SPF 15 protection.

With a breathable texture and color that stays true, the formula is designed for those who want control over shine and a smooth, camera-ready finish.

How does Studio Fix Fluid perform through a busy day?

Studio Fix Fluid is built for extended wear: the formula helps control oil and shine for several hours while maintaining color fidelity across the day. It’s resistant to humidity and sweat, so it remains intact during active or long schedules. Layering is possible without caking, allowing targeted touch-ups where needed.

• Up to 24-hour color stability for consistent tonality
• Oil and shine control for around six hours
• Humidity- and sweat-resistant finish for active days
• Non-cakey, breathable texture for comfortable all-day wear

What finish and coverage can I expect from shade C8?

Shade C8 delivers a natural matte finish that reduces the look of pores and smooths skin texture while remaining hydrating. Coverage is buildable: start with a light layer for a skin-like result or add more product where you want fuller coverage. The finish stays matte without looking flat thanks to the formula’s balance of moisture and oil control.

• Natural matte appearance that still looks luminous on camera
• Buildable coverage from sheer to full without caking
• Minimizes visible pores and blurs minor imperfections
• Suitable for spot layering and seamless blending

How should I apply Studio Fix Fluid for best results?

Prep skin with moisturizer and any primer you prefer, then apply the foundation to the center of the face and blend outward for the most natural result. A dense foundation brush (like M·A·C 130S) or a damp sponge yields smooth, even coverage; use fingertips for quick, lighter application. For a more luminous effect, mix a small amount with your favorite moisturizer or facial oil.

• Apply to hydrated, primed skin for even glide
• Use a brush, sponge, or fingertips depending on desired coverage
• Layer center-first to control coverage distribution
• Mix with moisturizer for a sheer, dewier finish if desired

Does the formula contain sunscreen and what are its key ingredients?
