A primer is like the first coat of paint you put on a wall or canvas, preparing it for the main color. π¨ It's a preparatory coating that ensures better adhesion and durability of the subsequent layers. Think of it as the foundation for a perfect finish. In makeup, a primer does the same thing for your skin before applying foundation. It creates a smooth, even surface, making your makeup last longer and look flawless. Like studying before a big test, it's all about preparation! It can also refer to a basic introductory book on a subject.
