What is it: A patented fluoride nail-strengthening system designed to combat specific nail problems.
Who is it for: The Overnight Barrier kit combats brittle, splitting, breaking nails; the ProCalcium kit targets aging, soft, hard-to-grow nails; the ProFlex kit tackles peeling, flaking, tearing nails; and the Biofusion kit is designed for thin, weak nails or nails damaged from gels and acrylics.
Why is it different: The patented fluoride formula penetrates nails for maximum strengthening. Fluoride penetrates to bond with nails' own calcium and grows out in the nail. No need to ever remove.
How do I use it: Apply steps 1 and 2 daily to penetrate and treat nails. Use step 3 nightly, or weekly, as directed, for maximum results.
