MAC Studio Fix Powder Plus Foundation C5 (0.52 oz) — Refillable Blur‑Matte, Longwear Oil Control

M·A·C Studio Fix Powder Plus Foundation in C5 is a refillable, two-in-one powder that delivers medium-to-full blur-matte coverage and longwear oil control in one compact.

This compact blends foundation and setting powder into a single step: a finely milled, pigmented powder formulated to even skin tone, minimize shine, and resist humidity for extended wear. The C5 shade reads as a deep neutral peach with golden undertone designed for medium skin tones that need warmth without appearing overly orange. The formula is travel-ready, waterproof, and created to remain color-true through daily activity.

How does this powder provide both foundation and setting benefits?

The formula is concentrated with pigments and smoothing powders so it can be applied to build coverage while also mattifying the skin’s surface. Applied with a sponge or brush, it fills in pores and blurs imperfections while leaving a soft, matte finish that doesn’t cake. Because it replaces two separate products, it shortens application time and reduces handbag clutter.

• Two-in-one: foundation pigments plus setting powder in a single compact
• Blur-matte texture that minimizes shine without appearing flat
• Suitable for sponge or brush application for buildable coverage
• Refillable compact design for eco-friendly reuse

Will the shade C5 match my skin and how does undertone show on medium skin?

C5 is described as a deep neutral peach with golden warmth, which means it leans slightly warm while keeping neutral balance so it doesn’t read too yellow or pink. On medium skin, it adds subtle warmth and evens complexion without shifting tones dramatically. If you’re between shades, test along the jawline in natural light to confirm the best match.

• Deep neutral peach with golden undertone for warm-medium complexions
• Designed to blend seamlessly along jawline and cheekbones
• Works well for those who prefer subtle warmth without heavy orange tones
• Try a patch test in daylight to verify a perfect match

How long does wear last and how does it handle oil and humidity?

The powder is engineered for long-lasting performance with oil control properties that help maintain a matte finish throughout the day. It resists sweat, humidity, and water, helping color remain true and reduce fading for extended periods. Results will vary by skin type and environment, but many wearers report reliable all-day control.

• 24-hour oil control formulation for reduced shine
• Waterproof and humidity-resistant for active days
• Fade-resistant pigments to keep color consistent
• Non-streaking and non-caking buildable coverage

What application methods produce the best finish?

Use a dense powder brush for lighter, airbrushed coverage or a damp/springy sponge for more concentrated, medium-to-full coverage. Pressing motions deposit pigment and smoothing powders into the skin while sweeping motions diffuse the edges for a natural look. Reapply to target areas only to maintain longevity and avoid over-layering.

• Brush: soft, sweeping motions for light to medium coverage
• Sponge: pressing for fuller coverage and more blur
• Touch-ups: blot oil first, then lightly press compact onto T-zone
• Refillable pan makes swapping shades or replacing product simple

Who is this for: This compact is suited to anyone seeking a streamlined routine—people who want foundation and setting powder in one durable, refillable format. It particularly benefits those with combination to oily skin or anyone living in humid climates who needs longer-lasting matte coverage. Choose C5 if you have medium skin that calls for a neutral-peach shade with a touch of golden warmth.
