👉 Cosmetics math, often referred to as cosmetic proportions or makeup ratios, is the art of balancing colors and textures in makeup to achieve a natural and harmonious look. It involves understanding color theory, where complementary colors (like red and green) can create contrast but should be used sparingly to avoid looking unnatural. For example, a foundation that matches your skin tone but slightly shifts towards the complementary color of your eye shadow can create a subtle yet striking effect. Texture ratios are also crucial; for instance, applying a light, sheer foundation followed by a matte eyeshadow can mimic the look of multiple layers without being overly heavy. Additionally, makeup artists use mathematical principles to calculate the right amount of product needed for coverage and finish, ensuring that each application is precise and effective. This blend of science and art allows makeup professionals to create looks that are both beautiful and true to the wearer's natural features.
