OPI Axxium gel nail polish is a specially formulated nail polish that is guaranteed to stay on your nails for at least two weeks. The secret is the gel formula's chemical consistency that creates a nearly indestructible barrier. However, this barrier is much more difficult to take off than it is to put on. So, unless you are especially skilled with a cuticle scraper, you'll most likely want to go to a salon for the removal.
File off the surface layer of the gel polish with an emery board. This is the soak-proof layer that will not come off with acetone.
Soak your nails in acetone for 10 minutes to begin dissolving the other layers.
Scrape off the layers of polish with a cuticle scraper, placing the nails back in the acetone once you can no longer scrape any more. Do not force the polish to come off or you could damage the nail.
