Drawing on almost two decades of experience, Dr Dana Stern is a board-certified dermatologist who set out to change how we think about nail care. Devoting her practice to the skinification of nails, her eponymous brand dreams up a renewal system to support the appearance of a stronger, shinier and smoother set. Nourishing everything from your cuticles to your skin (whether you're at home or when on-the-go), the collection includes buffing blocks, priming wands and more.
