What type of product is commonly used to prevent irritation during eyelash extension application?

The use of an eyelash extension primer is essential during the application process to minimize irritation and promote better adhesion of the extensions. Primers are specifically formulated to cleanse the natural eyelashes, removing any residue and oils that might interfere with the bonding of the adhesive. By ensuring that the lashes are clean and free of impurities, primers help to create a stable foundation for applying the eyelash extensions, thus reducing the risk of allergic reactions or irritation that might occur if the lashes were not properly prepared.

In contrast, water is generally not effective for this purpose, as it does not provide the necessary cleansing or pH balancing that a primer would. A moisturizer could potentially add oils or hydration that could lead to poor adhesion of the extensions, and an oily makeup remover would introduce oils that may cause the adhesive to fail, further leading to irritation or premature falling off of the extensions. Therefore, using a dedicated eyelash extension primer is the best practice for enhancing the safety and efficacy of the lash application process.
