Rapid Lash Eyelash Enhancing Serum holds the key to thicker, fuller, & denser-looking lashes. By nourishing & strengthening the lashes, they are protected against premature fallout & damaging environmental factors. In clinical trials*, the high-performance serum resulted in lashes that were 75% more voluminous & 50% longer, in just 30 days. The lash serum contains advanced Hexatein-1 complex, which helps transform brittle, fine, & sparse lashes into fuller, healthier-looking ones. Optimal results are seen after 8 weeks of daily use in the evening, before bedtime. On clean & dry eyes free of any make-up or creams, use the applicator brush to apply the serum to the lash line, starting from the inner corner of the eye & moving outwards. Wait until the serum has completely dried before applying any additional skincare products or cosmetics. Rapid Lash is dermatologist & ophthalmologist tested & is safe for use by contact lens wearers. For external use only, rinse with cool water if contact with the eye occurs. Stop use if you experience any irritation or discomfort. * Clinical study of 48 subjects over 84 days.
