MAC Studio Fix Powder Plus Foundation in C4 is a dual-use powder foundation that delivers buildable matte coverage and oil control for long-wearing, natural-looking finishes.

Newly reformulated, MAC's Studio Fix Powder Plus Foundation combines foundation and setting powder in a single compact, available in 67 shades to match a wide range of skin tones. The C4 shade reads as a light neutral-golden with a peachy undertone and is designed to provide a smooth, breathable finish whether applied dry for medium coverage or slightly damp for fuller coverage. Lightweight and versatile, this powder is intended to control shine while evening skin tone and simplifying touch-ups on the go.

How does Studio Fix Powder Plus Foundation deliver lasting oil control?

The formula is engineered to absorb excess surface oil, helping to maintain a matte appearance through the day without feeling heavy. It sets makeup and minimizes shine so skin looks refined from morning to evening.

• Pressed powder matrix disperses oil for a matte finish.
• Long-wear formulation resists color shift over time.
• Compact design allows quick touch-ups to reduce midday shine.

Can I build coverage or use it both wet and dry?

Yes — the powder is intentionally buildable so you can go from sheer to full coverage depending on application technique. Apply dry with the included sponge for medium coverage, or slightly dampen the sponge to intensify pigment and achieve fuller coverage without cakiness.

• Dry application yields natural, medium coverage.
• Damp application increases opacity for fuller coverage.
• Layerable without looking patchy or heavy.

Will the shade C4 suit my skin tone and undertone?

C4 is described as a light neutral golden with peachy undertones, suitable for lighter complexions that benefit from a warm, slightly golden finish. To verify the match, compare C4 to your usual MAC shade or test in natural light; MAC’s wide shade range helps you find a closer match if needed.

• C4: light with neutral-golden and peachy hints.
• Part of a 67-shade system for precise matching.
• Try a swatch on jawline in daylight for best match.

How should I apply Studio Fix for best results throughout the day?

For a polished base, start with clean, moisturized skin and apply using the compact’s sponge or a powder brush depending on coverage preference. Reapply sparingly only where oil or uneven tone appears to maintain dimension without overloading the skin.

• Use sponge dry for medium coverage, damp for full coverage.
• Set oily zones with a light powder layer to extend wear.
• Keep compact in your bag for easy touch-ups and shine control.

Who is this for? MAC Studio Fix Powder Plus Foundation in C4 is ideal for people seeking a single, travel-friendly product that acts as both foundation and setting powder. It suits those who prefer a matte, natural finish with flexible coverage options — from everyday lightweight wear to more polished, fuller coverage — and anyone looking to control oil while keeping makeup looking consistent throughout the day.
