Soak fingers for about 10 to 15 minutes in a bowl of very warm, soapy water (dish soap, hand soap etc.) with a few drops of oil (e.g. baby oil or olive oil).
Using a cuticle stick, gently slide under the nail edges until the nail loosens and comes off without force; resoak for 5 to 10 minutes if needed.
Then buff your nails to remove excess glue. Remember to add moisture to nails after removal (e.g. cuticle oil or hand cream).
