M.A.C Cosmetics Studio Radiance Face and Body Radiant Sheer Foundation in shade C3 (Medium Beige) is a liquid foundation formulated to deliver a natural, luminous finish while evening out skin tone. This 1.7 fl oz / 50 mL bottle contains a lightweight, water-based formula that blends sheer coverage with buildable layering, allowing for customizable radiance from a hint of glow to a more noticeable sheen. The foundation incorporates light-reflecting pigments and skin-conditioning ingredients, including hyaluronic acid and glycerin, which help maintain hydration without leaving a heavy or greasy feel. It is designed to work across a range of skin types, including normal, combination, and dry skin, and is suitable for use on both the face and body due to its non-transferring, streak-resistant consistency.

The shade C3 is a medium beige with neutral undertones, making it appropriate for fair-to-medium complexions seeking a balanced, natural-looking enhancement. The formula is free from oil, fragrance, and parabens, reducing the likelihood of irritation for sensitive skin. This foundation is intended for everyday wear as well as occasions where a subtle, skin-like appearance is desired, such as casual outings or layered under powder for longer events. It pairs well with primer or sunscreen and can be applied with fingers, a brush, or a damp sponge for different coverage levels. The sheer nature of the product means it evens out minor discoloration and redness without masking natural skin texture, making it a practical choice for those who prefer a minimal complexion routine. Its moderate price point reflects a balance between professional-grade performance and mass-market accessibility.
