MAC Studio Fix Powder Plus Foundation C4 — Light Neutral Golden, Buildable Matte Oil-Control

MAC Studio Fix Powder Plus Foundation in C4 is a dual-purpose powder foundation that delivers buildable, oil-controlling matte coverage and can be used wet or dry for up to 12 hours of wear.

Designed to bridge the gap between foundation and setting powder, this updated MAC formula comes in shade C4—described as a light neutral golden with a peachy undertone—and belongs to a 67-shade line crafted to suit varied complexions. The lightweight texture aims to provide a polished, natural finish while remaining breathable on the skin. Its versatility makes it suitable for everyday touch-ups or fuller coverage looks when applied damp with the included sponge.

How does this powder foundation perform throughout the day?

The formula is formulated for extended wear and oil control, helping skin maintain a matte, even appearance for long periods. It resists color shift and keeps coverage consistent so you can expect fewer midday touch-ups. Results vary by skin type and environmental conditions.

• Up to 12 hours of natural-looking, matte coverage
• Oil-controlling finish to reduce shine
• Stable color that stays true during wear

Can I customize coverage and finish with this product?

Yes—Studio Fix Powder Plus Foundation is built for flexible layering. Apply it dry with the sponge for medium, everyday coverage, or slightly dampen the sponge to intensify coverage and achieve a creamier, more complete finish. The powder format also doubles as a setting product over liquid base.

• Dry application: medium, natural coverage
• Slightly damp sponge: fuller, almost foundation-like coverage
• Works as a setting powder over liquids or creams

What shade is C4 and which skin tones does it suit?

C4 is described as a light neutral golden shade with peachy undertones, making it suitable for lighter complexions that favor warm-neutral tones.

If you’re between shades, consider adjacent options in the same family for the best match.

How should I apply and carry this powder for touch-ups?

Store the compact in a cool, dry place and clean or replace the sponge periodically for best hygiene.
