Which of the following is a potential risk associated with eyelash extensions?

Choosing dry eye syndrome as a potential risk associated with eyelash extensions is aligned with the understanding that the application process and the materials used can impact the natural eyes. When eyelash extensions are applied, they are adhered to natural lashes using a powerful adhesive. This can lead to a few factors contributing to dry eye syndrome.

Firstly, the use of adhesives may result in an allergic reaction or sensitivity that can cause irritation. Secondly, the procedure itself might cause some individuals to experience temporary discomfort or dryness, as the act of keeping the eyes open for the duration of the application and the close proximity of the lashes can affect the moisture levels in the eyes.

In contrast, the other options listed do not relate to risks from eyelash extensions. Improved vision, smoother skin texture, and brightening eye color are not outcomes associated with eyelash extensions and therefore cannot be considered risks in this context. Instead, these statements would describe benefits or unrelated effects that do not pertain to the health risks that may arise from the application of eyelash extensions. This distinction highlights why dry eye syndrome is correctly identified as a concern for clients and practitioners in this beauty treatment field.
