The core ingredients of matte foundation fall into four main categories, which are crucial for achieving oil control, long-lasting wear, and a matte finish:
Base Structural Ingredients
Oil-based ingredients: Primarily volatile silicones (such as cyclopentasiloxane) and isododecane; these provide a lightweight, non-sticky texture and help the pigments spread evenly.
Water-based ingredients: Water, glycerin, 1,3-butanediol, etc.; these balance the formula to prevent it from feeling too heavy or greasy.
Core Matte Powders
Includes pigments like titanium dioxide and iron oxides for basic coverage, combined with porous, oil-absorbing powders such as silica and kaolin to soak up excess sebum and create a shine-free, matte finish.
Functional Auxiliary Ingredients
Film-formers: Help create a breathable film on the skin's surface, enhancing the foundation's longevity and resistance to smudging.
Active ingredients: Commonly includes niacinamide, hyaluronic acid, and Centella asiatica extract, offering benefits such as oil control, brightening, hydration, and soothing.
Standard Additives
Includes emulsifiers, preservatives, and small amounts of ethanol to maintain formula stability; some products utilize ethanol to further enhance the lightweight, oil-controlling feel during application.
