What are under eye stickers used for during eyelash extension application?

Under eye stickers play a crucial role during eyelash extension application primarily by separating the bottom lashes from the top lashes. This separation is essential for several reasons. First, it prevents the bottom lashes from sticking to the extensions being applied to the top lashes, which can lead to discomfort and an undesired look. Secondly, it allows for greater precision during the application process, ensuring that each extension adheres correctly to the natural lashes without interference. By using under eye stickers, the technician can create a cleaner and more professional result, ultimately enhancing the overall experience for the client.

The other options, while they may seem plausible, do not accurately reflect the primary purpose of under eye stickers in the context of eyelash extension application. For example, promoting quicker lash growth is not a function of these stickers, and while they might provide some comfort, their main role is focused on separation rather than minimizing discomfort or enhancing adhesion.
