MAC Studio Fix Powder Plus Foundation C40 — 0.52 oz pressed powder, matte 12-hour oil-control coverage

MAC Studio Fix Powder Plus Foundation in C40 is a pressed powder foundation that delivers medium-to-full, matte coverage for up to 12 hours.

Compact and versatile, this 0.52 oz powder from MAC is designed to control oil, reduce shine, and create a smooth, natural-looking finish. Its finely milled texture blends easily across the skin and can be worn alone for quick touch-ups or layered over liquid foundation for added staying power and coverage. The C40 shade suits medium to tan complexions with neutral-warm undertones and is formulated to work especially well on oily and combination skin types.

How does this powder foundation perform on oily or combination skin?

The formula targets excess shine while maintaining a natural skin-like appearance. It mattifies without feeling overly dry, so skin looks refreshed rather than flat. Texture and pore visibility are softened for a smoother overall complexion.

• Controls oil and shine for extended wear—up to 12 hours in typical conditions.
• Medium-to-full coverage helps blur imperfections and evens out skin tone.
• Lightweight feel avoids cakiness, even in areas prone to sebum buildup.

Can I use MAC Studio Fix Powder Plus Foundation C40 over liquid foundation?

Yes—this compact is formulated to layer over liquids to boost coverage and longevity without creating a heavy finish. Apply sparingly with a brush or sponge and blend outward to maintain a seamless transition between products. It also works as a convenient setting powder for touch-ups during the day.

• Use a fluffy brush for light setting or a dense sponge for more coverage.
• Layering helps lock in makeup and extend wear in humid conditions.
• Portable compact is ideal for midday blotting and quick fixes.

What coverage and finish should I expect from shade C40?

Shade C40 provides medium-to-full coverage with a true matte finish that looks natural in daylight and photography. The color matches medium tan skin tones with warm-neutral undertones and helps even redness or discoloration without looking chalky. Build coverage in thin layers to avoid overapplication while achieving desired concealment.

• Medium-to-full coverage conceals imperfections and evens complexion.
• Matte finish reduces shine, suitable for flash photography.
• Shade selection aimed at neutral-warm medium-tan skin tones.

How should I apply and maintain the compact for best results?

Start with clean, moisturized skin and, if needed, a primer to improve wear. Apply the powder with a large brush for an all-over matte effect or press with a sponge where you need more coverage. Keep the compact clean and store it in a cool, dry place to preserve texture and shade integrity.

• Brush for light coverage, sponge for fuller coverage and spot correction.
• Touch up T-zone or oily areas throughout the day with a blotting puff.
• Replace if texture changes or if shade shifts after extended storage.

Who is this for: MAC Studio Fix Powder Plus Foundation in C40 is aimed at wearers with oily or combination skin who want a reliable matte finish and buildable coverage in a portable compact. It’s suited to makeup users seeking a quick, single-step product for daily wear, photographers and professionals needing photo-friendly results, and anyone who wants the option to layer powder over liquids for increased longevity.
