In terms of makeup, what does "contouring" involve?

Contouring involves using makeup techniques to create the illusion of shadow and depth on the face, which helps to enhance and define facial features. This technique typically utilizes darker shades of makeup to simulate shadows on specific areas like the sides of the nose, under the cheekbones, and along the jawline. Conversely, lighter shades can be applied to the high points of the face, such as the forehead, cheekbones, and chin, to enhance these areas. By skillfully applying and blending these products, an artist can sculpt the face to appear more defined and dimensional.

The other choices focus on different aspects of makeup application and care. Applying foundation evenly is a foundational step in makeup, but it does not involve the specific technique of contouring. Cleansing the skin is an essential preparatory step before applying makeup, ensuring a clean and healthy canvas, but it is unrelated to the contouring process itself. Tracking makeup trends is about observing and adapting to new styles and looks in the industry, which does not pertain to the practice of contouring as a technique.
