The NYK1 LashForce, BrowForce & Brow Brush Bundle pairs two concentrated growth serums with a Line&Define duo brush. LashForce and BrowForce regenerate, rebuild and activate length and thickness while protecting each follicle - applied in seconds twice daily, thin and unnoticeable, safe for contact lens wearers, with fuller lashes and brows in 6-8 weeks. The angled, firm-bristled brush gives a defined line on brows and lids, while the grooming spiral shapes unruly brows and separates lashes.
