The isolation technique is primarily used to apply eyelash extensions because it focuses on separating individual natural eyelashes to allow for precise placement of extensions. This method ensures that each extension is attached to a single natural lash, which is essential for achieving a clean, natural look while minimizing the risk of damaging the natural lashes.

By effectively isolating each lash, the technician can also ensure that the extensions adhere properly, facilitating optimal bond strength with the adhesive. This technique is crucial for creating volume and length without risking clumping or discomfort to the client. Proper isolation helps in maintaining the longevity of the extensions and contributes to the overall aesthetic appeal of the finished look.

Other techniques, while relevant in different contexts, do not serve the same purpose in the application of eyelash extensions. For instance, the fanning technique involves creating a fan of multiple extensions to attach to a single natural lash, which is a different approach. The pinching and pumping techniques have different applications entirely and are not standard practices for the application of individual eyelash extensions.
