What is magnetic nail polish?
There are many ways to accomplish creative fashionable nail appearances. One of the currently popular nail polish techniques important to the dermatologist is magnetic nail polish. Magnetic nail polish is removed from the bottle and painted over the nail like traditional nail polish, except it contains magnetic particles, such as nickel, cobalt, iron, gadolinium, terbium, and erbium. The most commonly used metal is magnetite, also known as iron oxide. While iron oxide, the brown pigment used in facial cosmetics, is not a problem, the nickel containing nail polishes may cause allergic contact dermatitis in nickel allergic patients.
The magnetic particles are asymmetric and oblong allowing them to create novel shapes and patterns when a magnet is placed over the wet nail polish. Many different magnet configurations can be used to create different appearances with the same nail polish. The magnets can be oriented in lines, circles, squares, etc, each creating a different appearance. The popularity of this nail polish with young females is the individualized customized appearance, allowing everyone to have unique appearing nails. The dermatologist should ask about magnetic nail polish in a patient who presents with periungual swelling and possibly eyelid dermatitis.
