Supplies the nails with more keratin, more hydration, and promotes silicon - meaning your nails become stronger and more protected.
Contains cationic hyaluronic acid, which promotes hydration in the cuticles.
Easy to use, with a click-pen applicator dispensing serum that absorbs quickly with an invisible finish.
To be applied over clean, dry nails (do not use over polish).
