As Jennifer Lopez announces that she took 8 hours to remove her gel nails we have a got a step by step for you to follow, that is hopefully quicker:
Buff the nail all over with a nail file to reduce the shine and remove the topcoat.
Wrap the nail with a cotton pad soaked in 100% acetone ( available from chemists)
Cover with tin foil
Hopefully, after 20 to 30 minutes and not 8 hours they will be able to be removed with a cloth, and an orange wood stick if you have one
Finish by moisturising with hand or nail cream, and ideally a cuticle oil
