The DUPLEX is a two-sided buffer that helps control ridges and flaking and splitting at the nail tips.
DUPLEX 1 Refine helps manage ridges. Buff lightly back and forth across the entire nail surface. Nail ridges and grooves are reduced and smoothed and the nail surface is left more even.
DUPLEX 2 Shine has three functions. It helps work Renovate Nail Therapy cream into the nail surface, it then creates a protective gloss over the nail, and thirdly, it is the perfect way to manage cracking and flaking nail tips as it smoothes and flattens to discourage catches on fabrics that pull on flaking nail causing further damage.
