YSL All Hours Foundation - MN4

Comparing swatches from multiple sources, checking online shade finders (if available), and referencing user reviews with similar skin tones can help. However, testing in person remains the most reliable method.

Yes, this foundation is designed for buildable coverage. Apply a thin first layer, allow it to set slightly, then add small amounts to areas where more coverage is desired, gently tapping and blending.

The best method depends on your desired finish. A dense brush provides fuller coverage, a damp beauty sponge offers a natural, airbrushed look, and clean fingertips can give a sheer, skin-like finish.

While not strictly required, using a primer is highly recommended, especially with a 'long-wear' foundation like All Hours. A primer creates a smooth base, extends wear, and can enhance the finish.

Keep the foundation in a cool, dry place, away from direct sunlight, extreme heat, or cold. Always ensure the cap is tightly sealed after each use to prevent air exposure and drying out.

The All Hours Foundation is generally formulated for a range of skin types, particularly those seeking a matte, long-wearing finish. However, individuals with very dry skin may benefit from extra moisturizing and a hydrating primer beforehand to prevent it from clinging to dry patches.

Ensure your skin is thoroughly cleansed, moisturized, and primed before application. Use a minimal amount of product and blend it out thinly and evenly. If using a brush, try a damp sponge for a more natural finish.

Some foundations can oxidize slightly on the skin, causing them to darken. Always test a shade on your jawline in natural light and allow it to dry completely before making a final decision. Consider a shade slightly lighter if oxidation is a consistent issue.

To maximize wear, always use a primer suited for your skin type (e.g., mattifying for oily skin) and set the foundation with a translucent powder, especially in your T-zone. A setting spray can also significantly extend wear.

Apply a smaller amount of product and blend it out with a damp sponge for a sheerer, lighter feel. Alternatively, mix a tiny drop of your favorite facial oil or liquid illuminator with the foundation for a less dense application.
