Bio Sculpture offers a permanent nail colour that lasts for weeks without wearing or chipping. The advantage of Bio Sculpture Colour Gel is that you can easily change your nail colour by simply applying Bio Sculpture Varnish. Later the polish can be removed with Bio Sculpture's specially formulated non-acetone cleanser and the permanent nail colour will be restored to its original state. When wiped with non-acetone cleanser the permanent colour will not be removed in the same fashion as nail varnish.
