Which technique is commonly used for applying eyelash extensions?

The isolation technique is fundamental in the application of eyelash extensions as it involves separating each natural lash to ensure that the extension is applied accurately and safely. This ensures that the extension is not attached to more than one natural lash, which can lead to damage or breakage of the natural lashes. Proper isolation allows for better control during the application, resulting in a more natural and aesthetically pleasing look.

In the context of eyelash extension application, using this technique maximizes the longevity of the extensions and helps in achieving a balanced and even distribution of the extensions across the natural lashes. It also minimizes the risk of discomfort for the client, as each lash is treated individually, ensuring that the extensions are securely applied without causing strain on the natural lash.
