The key is clean, prepped nails and proper application. May be applied on its own or as a base coat with polish over it. 

Application:Apply one coat of nail strengthener/base coat on clean and dry nails. May be used as strengthener only or doubled as basecoat. If using as strengthener only, use 2-3 times per week for two weeks. Remove and reapply original application.

    Amazing base coat or clear coat

    This stuff is magic. I started using it after I did the First Aid Kiss treatment. My nails were a mess from gels. I love the shiny quality to it so sometimes I would leave it on without putting a color over it. But now I use it as my go-to base coat. My nails are so much stronger and healthier. And I don't know if it helps but my polish lasts forever!
