Been using their SohoSilkRidgeFiller and SecheViteTopCoat for a month. Nails seem more pliable. First time in years, that both thumbnails have extended past the thumbtip, to match the other fingernails. I think LD's CrystalFile works wonders and ProStrong helps with the length. Who have I left out? Oh yes, OPI polish rounds it off. Cocktailing. Please let this be the right formula for ever and ever. Amen.
