Review (4/5): Depends on the gel brand
I just started using gel polish and only because this product exists. I don't see how this can be more harmful than acetone, in terms os toxicity is probably the same as soaking you fingers on solvent for 20min. Anyway, I noticed that the gel brand makes a difference on how many layers you'll have to apply, maybe one, maybe two or even three (glitter took me three). It works. Yes it is a chemical compound, as is everything you apply on your nails.
