CND introduces a groundbreaking nail care product, CND Strengthener RXX, designed to enhance and fortify natural nails. This treatment harnesses the power of celery seed extract and Tsubaki oil to increase nail thickness and create a smoother surface. Its gentle, quick-drying formula forms a protective shield that aids in nail growth and repair, resulting in stronger nails within two weeks. The breathable, vegan formula allows for water and oxygen permeability, making it suitable for both DIY users and salon professionals. You can use CND Strengthener RXX on its own for nail strengthening or as a base coat under your favorite Vinylux polish.
