Which type of gel nails need to be soaked in acetone for removal?

The correct answer is soft UV gel, which is specifically designed to be removed easily compared to other types of nail enhancements. Soft UV gels are applied similarly to traditional polish but have a longer-lasting durability. When it's time for removal, they are formulated to break down in acetone. This makes soaking in acetone an effective and efficient method for safely removing soft UV gel without damaging the natural nail underneath.

Hard gel, builder gel, and traditional acrylic nails, on the other hand, generally require filing or buffing to remove, as they are designed to provide a durable structure that is more resistant to solvents like acetone. These materials attach more firmly to the natural nail, necessitating more abrasive methods for removal instead of soaking. Therefore, understanding the properties of each type of gel is crucial for safe nail care practices and choosing the correct removal method.
