M.A.C Cosmetics Studio Radiance Serum-Powered Foundation in shade C3.5 is a liquid foundation that combines medium-buildable coverage with a luminous skin finish. Infused with a blend of moisturizing ingredients and a serum-like texture, this formula aims to support skin’s natural radiance while evening out the complexion. The shade C3.5 is described as a light to medium beige with a peachy undertone, suitable for individuals with fair to medium skin tones who prefer a warm, subtle glow without heavy yellow or pink casts.

The foundation is designed to provide a natural-looking, dewy finish that can be layered for increased coverage without settling into fine lines or emphasizing texture. Its lightweight, fluid consistency allows for easy blending using fingers, a brush, or a damp sponge. The formula includes skin-conditioning components such as glycerin and squalane, which help maintain hydration throughout wear, making it particularly well-suited for normal to dry skin types. Those with combination skin may also find it works well when set with a light dusting of powder.

This product delivers a radiant, skin-like appearance rather than a full-coverage matte look, making it ideal for everyday wear, special events, or photography under natural light. It is packaged in a 1 fl oz (30 mL) frosted glass bottle with a pump dispenser for controlled application. As with other M.A.C foundations, Studio Radiance provides a broad spectrum of shades to match various undertones. The formula is free from parabens and sulfates, and it is non-comedogenic. For best results, prep the skin with a moisturizer or primer suited to the individual’s skin type.
