Biện pháp cuối cùng là dùng acetone hay chất tẩy sơn móng tay.

I'm interested in that, but I only have a few mins. Can you give me at most the first 500 characters of a detailed explanation in Chinese about that?
但是这两种方法都会破坏指甲油的成分，之后涂在指甲上，干了以后可能会开裂。 如果你选择这种方法，就要做好准备，这样处理过的指甲油用几次以后可能就要淘汰了。 不要用丙酮或者洗甲水处理凝胶指甲油。
