Triple Lanolin Hand And Nail Conditioner. Specifically formulated to soften the cuticle while hardening the fingernail, our Hand & Nail Conditioner really works. It does so by utilizing a rich blend of lanolin for cuticle softening, and a natural protein called keratin for hardening the actual nail surface. For best results, simply apply a drop of Triple Lanolin Hand & Nail Conditioner to the cuticle area on each finger, and gently massage it into the cuticle border and fingernail area. Any excess lotion can then be massaged into your hands.
