The IRIS Pro-Strength Eyelash Serum is designed to provide you with naturally voluminous and dramatic lashes every day. 
- Helps lashes become stronger: It contains ingredients such as phytokeratin which “repair and protect lashes … increasing hydration and elasticity.”
 - Supports growth/volume: With L-Arginine (improves circulation to the hair root) and Anagain (promotes new hair growth) the formula aims to stimulate lash growth and density.
 - Improves lash appearance: The serum promotes softer, shinier, fuller-looking and denser lashes (from root to tip) rather than just longer.
