My nails are painted 24/7. Is that bad?
If you can’t live without your weekly mani, don’t worry: Polish isn’t harmful to the health of your nails, says Dr. Vivian W. Bucay, a dermatologist and assistant clinical professor at the University of Texas Health Science Center in San Antonio, Texas. That said, skipping basecoat prior to painting on darker shades can result in your nails yellowing, thanks to a chemical reaction between the polish and your nail plate. So layer on that lacquer and you’ll be good to go.
