How to use:
Apply SI-NAILS daily to clean, dry nails. The best results are achieved if the nails do not come into contact with water for up to 6 hours after application. We therefore recommend applying before going to bed. Otherwise, SI-NAILS can be reapplied after washing your hands.
Before using SI-NAILS for the first time, press the button around 25 times until the brush is moistened. After activation, only one click per nail is required.
With continued use, the results improve even further.
