Amber Hardener

This new nail strengthening product contains succinic acid and vitamins B5, E & C and is designed for thin, brittle nails. It applies almost as a transparent base, however it dries very fast and after drying it creates a very thin film even if you applied a generous amount of product. You can use it both as a nail treatment, applying 1-2 coats every 2-3 days and as a base for any coloured polish, applied in 1 coat (in this scenario, it will not only help your nails grow stronger, but also make your nail polish last 1-2 days longer).
