Foundation is a cosmetic product that is applied to the face to create an even, uniform color to the complexion, cover flaws, and sometimes change the natural skin tone. It is typically used as a base for other makeup products such as blush, bronzer, and highlighter.

Foundations come in various forms such as liquid, cream, powder, and stick, catering to different skin types and preferences. Selecting the right foundation can help achieve a smooth and flawless finish for your makeup look.
