What is the rule regarding the use of acetone on artificial nails?

The use of acetone on artificial nails is a significant consideration for nail technicians. While acetone is a powerful solvent commonly used to remove nail polish and artificial nails, it can indeed damage the surface of artificial nails, particularly those made from acrylic. This damage may manifest as a dulling of the finish or a breakdown of the integrity of the artificial material, leading to weakening or peeling.

Acetone works well to dissolve specific types of materials, but its effects can be harsh, especially on products that are not designed to withstand prolonged exposure. This is why it's essential for technicians to be aware of the materials they are working with and to use acetone judiciously.

In the context of the other choices, it’s important to note that while acetone is a preferred solvent in certain situations, it is not suitable for all nail types, especially when considering the preservation of artificial nails. Thus, while acetone may be used for removal and maintenance, care must be taken to protect the integrity of the artificial nails during the process.
