Base Brillante is the newest makeup base offered by Sonia Rykiel. It is a thin, light, white makeup primer that smooths over and reduces the appearance of imperfections, allowing for a better foundation application. I had absolutely no pilling or drying problem with Brillante and it instantly blended into my skin. The L'Atout Eclat Sublime base was another story. L'Atout Eclat is a flesh-colored primer that contains fine pink pearls for a nice sparkle. The primer was too dark for my skin tone, making it look even more red and dry, and simply sat on my face instead of sinking into my skin. While the foundation was very even and smooth when I applied it over Base Brillante, it was very uneven and somewhat drying when used over the L'Atout Eclat base.
The Eclateint Foundation itself was quite wonderful. The sample I received was 30 which is probably closer to something between an OC10 and OC20 for other makeup brands though it's coverage may just make it appear lighter than it really is. It is yellow-based but not quite as yellow as most other Japanese foundations. When it touched my skin, the foundation was incredibly cool and soothing which is what I liked most about it. Other foundations can feel suffocating but Eclateint is light and actually feels nice on the face. The coverage is light to medium and the high water content causes it to blend well and look natural. Those who want heavier coverage might find Eclateint to be too sheer but even with my rosacea face, I prefer it's light coverage. Lunasol's Skin Fusing Powder Foundation and Shiseido's Hydro-power Perfect Smoothing Foundations are somewhat similar to Sonia Rykiel's foundation but Eclateint is the smoothest and softest of them all. I am very pleased with both Eclateint and Base Brillante and I would most definitely consider purchasing the foundation if they had it in my skin color.
