Which type of adhesive is commonly used for eyelash extensions?

The correct choice is semi-permanent adhesive suitable for sensitive eyes because eyelash extension adhesives are formulated specifically to bond the extensions to natural lashes for an extended period, ranging from several weeks to several months. This type of adhesive generally contains ingredients that provide a strong hold while remaining flexible enough to accommodate the natural movement of the lashes.

Additionally, sensitive eyes may react to strong fumes or particular compounds in adhesives, so products designed for sensitive eyes typically have lower amounts of irritating agents. Choosing a semi-permanent adhesive ensures that users can enjoy their extensions without discomfort, while also emphasizing the importance of safety and comfort in applications.

Other types of adhesives like temporary adhesives are not suitable for lash extensions, as they are designed for short-term use and won't provide the lasting hold desired. Water-soluble adhesives lack the strength needed for the long-term application of extensions, leading to performance issues. Clear adhesives that dry quickly could be effective for some applications but may not address the needs of sensitive clients effectively. Thus, semi-permanent adhesive that's suitable for sensitive eyes stands out as the best option for eyelash extensions.
