If the edges of the nails are worn out, be sure to use a nail file to smooth them. It should be noted that nail files and nails should be kept at a certain angle, generally 90 degrees.
Apply a layer of armor cream to the soft skin of the nails, and then soak your hands with warm water until the soft skin becomes soft.
Use a cotton swab to gently remove the soft skin, taking care not to use too much force, so as not to hurt the rest of the nail.
After gently removing the remaining soft skin with gauze, apply a layer of armor oil. This will protect the perfect nails.
