The best way to find your perfect shade match is to test the foundation directly on your jawline in natural light. If purchasing online, utilize online shade finders or compare with shades you already know work for you.

The specific variant 'Yves Saint Laurent - All Hours Foundation - 25ml - DC9' does not explicitly state SPF protection in its description. If sun protection is desired, consider layering with a separate SPF product.

For optimal results, apply with a clean foundation brush, a damp beauty sponge, or even clean fingertips. Start with a small amount and build coverage as needed, blending outwards from the center of your face.

The duration of a 25ml bottle depends on frequency of use and the amount applied per application. For daily use with moderate coverage, it generally lasts 1-3 months.

Ensure skin is well-exfoliated and moisturized before application. Use a primer for a smoother canvas. Blend thoroughly using small, circular motions.

Apply a good quality primer before foundation. Consider setting your foundation with a translucent powder, especially in oily areas or for extended wear.

Allow the foundation to fully dry on the skin to see its true color. Always test shades on your jawline in natural light before purchase to ensure an accurate match.

Use less product and build coverage gradually. A damp beauty sponge can help sheer out the foundation for a lighter feel. Ensure your moisturizer has fully absorbed.
