If you don't apply a clear base coat on your nails before applying the black nail polish, your nails can stain. This can happen with any of the darker nail polish colours.

Yes, it rots your skin and can cause you to turn blue (Or the color of the polish).
Someone can have a bad reaction to nail polish. Those with sensitive skin can experience a negative reaction that can affect the nail bed as well as the surrounding area.
Yes!! Don't do it
no it is just showing how you feel.
take the nail polish off if your going to do acrylic nails yourself, it'll look bad if you dont and you can't make the nails stick good with polish on
Clear nail polish is a special coat of nail polish to protect the other coat of nail polish
Yes it can because nail polish remover is bad for your nails and if you peel it of you feel off the protective nail fibres also dark colour like red and black can turn your nails yellow so you should use a clear nail polish underneath or avoid wearing them. Also nail strenghteners and protective nail polish remover can stop your nails being ruined. Hope I helped!
