Is nail polish harmful if ingested by a child?

I think that metallic nail polsih may be bad for kids but only in those ages 3 and below. I would encourage children ages10 to 15 to wear nail polish due to the fact that they are a constant expression of style and fashion sense plus the are a way to contiuously boost confidence and self esteem. I believe wearing nail polish cannot harm your health or academic standings but should not be reapplicated week after week of daily. It should be applicated once a month and shouldn't be left on for long amounts of time. Thank you for reading this answer.
