Gradual but noticeable improvement to lash length and strength
I have been using COS Peptide Lash for five weeks, applying once daily right before bed. My lashes are thin and straight. I can see sparse areas filling in and lashes appear thicker and slightly longer. I’m encouraged by this progress and will continue using. The cosmetologist who tints my lashes could see a positive change, too.
