What is the best method to remove hard gel from nails?

Filing and buffing is considered the best method to remove hard gel from nails because it allows for precise control and minimizes damage to the natural nail. This method involves using a coarse file to break through the gel layer gradually, followed by a finer buffer to smooth the nail surface after the gel has been removed. It is important to be gentle while filing to avoid excessive thinning of the natural nail.

Soaking in acetone is not effective for hard gel, as it typically requires a much stronger solvent or physical removal. Using a nail clipper might lead to uneven removal and potential harm to the nail matrix, as it is not meant for removing gels. Applying a softener could be suited for softer products, like regular nail polish or soft gel, but it wouldn't effectively penetrate or break down hard gel. Thus, the filing and buffing technique is the safest and most effective approach for hard gel removal.
