Cosnetic Lash Clusters are water resistant. You can easily take a shower, swim, practice water sports and exercise while wearing our Lash Clusters - But you should wait 24 hours after application. We do not recommend spraying water from the shower directly on the lashes. Exposure to steam will loosen and soften the bonds. If they get wet, let them dry completely before touching them. If they loosen, simply add extra bond and reuse.
