The technique of buffing is crucial for achieving a seamless blend of eyeshadow. Buffing involves using a soft brush or tool in a circular or gentle back-and-forth motion, which helps to feather the edges of the eyeshadow colors together. This technique not only softens harsh lines but also creates a more natural transition between different shades, making the overall eyeshadow application look polished and professional.

In the context of eyeshadow application, other techniques like dabbing, tracing, and sweeping serve different purposes. Dabbing is more focused on applying product in specific areas without blending, which can lead to noticeable edges rather than a seamless look. Tracing typically refers to the application of product along the lash line or in a defined shape, which doesn't promote blending. Sweeping, on the other hand, can help with initial placement, but it may not effectively merge the colors as well as buffing does. Thus, buffing stands out as the most effective technique for blending eyeshadow seamlessly.
