Abstract

Magnetic nails, also known as a magnetic manicure, or magnetic nail polish, is a new trend in nail cosmetics which is quickly becoming popular. More commonly known nail cosmetics include the use of gel nail polish, acrylic nails, and nail stickers. Magnetic nail polish incorporates magnetic metal particles within the polish to create unique and attractive designs. After application of a base coat, magnetic nail polish is applied and activated by a magnet. The magnet is held above the coat before it dries to create designs employing magnetic polarization. The metal particles are typically darker than the base coat, creating a wavy pattern on the nail plate. A top coat can then be applied to help set the design. Here we present an example of magnetic nails, and demonstrate the histopathologic, clinical, and dermatoscopic features of it. On exam, the nail plate demonstrated a background of uniform nail polish with an overlying metallic wavy pattern. The magnetic particles polarized with onychoscopy. Histopathology demonstrated a thick clear homogenous band overlying a separate band that included fragments primarily perpendicularly arranged, which were polarizable, on the dorsal aspect of the nail plate. Recognition of both the histopathologic and clinical aspects of magnetic nails are essential, as potential adverse events such as allergic contact dermatitis to the metal or other components, may become an issue in the future as more individuals engage with this trend.
