What it is

This product is a foundation designed to provide a natural matte finish. It offers a buildable medium-to-full coverage that aims to diminish the appearance of pores and fine lines, and is intended to maintain a consistent look throughout the day.

Key ingredients and their functions

• Octinoxate - UV filter

How it works

The foundation appears to work by creating a matte finish on the skin with the help of mattifying agents such as Polymethylsilsesquioxane. The buildable coverage is facilitated by the film-forming properties of Acrylates/Polytrimethylsiloxymethacrylate Copolymer, which allows for layerable application. Key ingredients like Butylene Glycol and Glycerin attract moisture, which may contribute to a smooth and even appearance, while Cyclohexasiloxane and Isododecane enhance the texture and feel on the skin. Octinoxate serves as a UV filter, offering some level of sun protection, while Synthetic Fluorphlogopite helps improve the texture and spreadability of the product. Together, these components give the foundation its characteristic coverage and long-lasting wear, which aims to maintain skin's flawless appearance throughout the day.
