Nail care product formulated with urea, salicylic acid, and piroctone olamine, recommended by dermatologists and podiatrists to restore and promote healthy nails thanks to the softening and keratolytic action of its ingredients, with visible results from the first days of application. Directions for use: External use. Use the nail file included in the package (or any other nail file) to file the entire surface of the affected nail. Apply a small amount of the product with the brush and cover the entire surface of the nail. After a few minutes, the product dries, creating a thin film on the nail.
