Bio Sculpture Gel nourishes your nails; helping them grow and strengthen beneath what I guess could simply be called a thick varnish. If you have weak nails then even better, those are the nails that Bio Sculpture Gel treatments were initially designed for!
Gluing bits of plastic onto yourself is something to be grown out of, not encouraged
Fake nails damage the nail bed at best and at worst, if a manicurist doesn’t properly clean their tools I’ve heard of many people faced with nail fungus that only leaves after several months of treatment.

I agree. I contracted nail fungus from acrylic nails and it has taken me a while to get my natural nails back to normal. Be careful with fake nails!
