Are your nails ridged, weakened or damaged? The COLOR SMOOTH range is our answer for nails marked by ridges. These smoothing care polishes combine beautiful colour with a trio of active ingredients (collagen, AHA, silicon) to visibly fill irregularities and lastingly smooth the nail surface. Their formula, very well tolerated even on weakened nails, remains permeable to PODERM® serums so it fits into a complete care routine.
