What is lash primer for eyelash extensions?

Unlike regular lash primer which helps with mascara application, lash primer for eyelash extension is designed to aid lash artists by speeding up attachment time.

Lash extension primer typically contains a few basic ingredients that serve different purpose:

  • Alcohol (the most important ingredient). It can be Ethyl alcohol or Ethanol. Which are important components as it helps in dissolving and removing oils, dirt, and residue makeup from the natural lashes, providing a better surface for lash extensions to adhere to.
  • Acetic Acid or Acetic Anhydride: They are added to the lash primer for eyelash extensions to adjust the pH level. Maintaining the right pH level is crucial to ensure the lash adhesive work effectively.
  • Silane or other bonding agents:They act as a bonding agent that helps create a strong bond between the natural lashes and the lash extensions. It enhances adhesion, ensuring that the extensions stay in place for a longer period.

In contrast, high-porosity lashes have rough surfaces that provide excellent grip for lash extensions. In such cases, using Primer can be considered as a deep-cleansing step to eliminate temporary oil from natural lashes, preparing a clean surface for better retention.
