Which of the following types of gel nails require soaking the nail in acetone remover to remove the nails?

Soft UV gel nails are designed to be easily removed by soaking in acetone remover. This is because they are formulated to be less resilient and more pliable compared to other types of gel nails. The acetone effectively breaks down the soft gel, allowing it to be gently wiped or pushed off the natural nail without causing damage.

In contrast, hard gel nails are more durable and require filing rather than soaking for removal, as they do not dissolve in acetone. Polygel nails, which combine properties of both hard and soft gels, are typically filed off as well, and builder gel also falls into the category of hard gel. Therefore, these other types do not require acetone soak for removal, making soft UV gel nails unique in that aspect.
