Why Is Nail Polish Turning My Fingernails Yellow? Dermatologists Explain

There’s nothing better than a fresh, glossy manicure. But sometimes, it can come at a cost. If you wear nail polish often, your nail bed can turn yellow over time. Though this is a common occurrence, it’s still natural to wonder why it happens in the first place. So, of course, we went straight to the experts to find out the science behind why nail polish causes fingernails to turn yellow. Ahead, two board-certified dermatologists share everything you need to know about this phenomenon.

Can Nail Polish Really Turn Fingernails Yellow?

Short answer: Yes, your nail polish can turn your fingernails yellow. “Polish staining occurs because the porosity of the nail is variable,” Dr. Stern says. “Certain people have more porous nails and are more prone to pigment migration and thus yellowing.”

Dr. Garshick adds that some colors create more yellowing than others. “Nail polish can turn fingernails yellow because certain dark-colored polishes, especially those with high pigment levels, can stain the nails,” she explains.

Dr. Stern also points out that polish remover is a culprit. “Polish remover dissolves polish and makes the pigments migrate and leach or absorb into the nail,” she says. We may see more yellowing with the no-chip or gel manicures, which require 10-minute soaks in acetone for removal.”

Should I Be Worried About It?

Nail yellowing caused by polish is typically not cause for concern, but it’s important to look for additional signs of poor nail health. “While it’s not something to be overly worried about, it can indicate that the nails have been exposed to polish for too long without a break, which might cause them to become dry or brittle over time,” Dr. Garshick says.

There are some instances where yellow nails can indicate other medical conditions. “Beyond polish-induced nail yellowing, the color of your nails can sometimes provide clues about underlying health issues,” Dr. Stern says. “Yellowing of the nails can result from fungal infections, or more rarely, a nail entity called Yellow Nail Syndrome (usually due to an underlying lung issue). In Yellow Nail Syndrome, the nails will grow extremely slowly, become thicker, and lack a cuticle.”

Can I Get Rid Of It?

You can get rid of yellow fingernails using over-the-counter products or at-home remedies. Dr. Stern suggests using her Dr. Dana Nail Renewal System. “The combination of Glycolic Acid and the right amount of exfoliation will help tremendously,” she says.

If you want to take the DIY route, you can try a few methods. “Soaking your nails in a mixture of baking soda and lemon juice or applying a whitening toothpaste can help remove stains over time,” Dr. Garshick says. “Some people have mentioned applying it and leaving it on for 10 to 15 minutes and then rinsing it off under warm water with a toothbrush or nail brush to help eliminate stains, but try to avoid rubbing too hard as this can be abrasive.”

Alternatively, you can use hydrogen peroxide to whiten yellow fingernails. “If stains are severe, they can be lightened additionally by diluting Hydrogen Peroxide (H202),” Dr. Stern says. “Combine three to four tablespoons of H202 and 1/2 cup of water, mix well, then soak nails for two minutes. Using a soft toothbrush, gently scrub the surface of the nails. Rinse with water. Repeat two or three times per week as needed.”

No matter which method you choose for treating your stained nails, use your favorite hand cream and cuticle oil afterward to alleviate any dryness. “It is important to still moisturize and nourish the nails after applying anything that may be harsh on the skin,” Dr. Garshick says.

Can I Stop It From Happening?

Thankfully, you can take steps to reduce your chances of yellowing. According to Dr. Garshick, the best thing you can do is “give your nails a break between polish applications to let them breathe.” Both dermatologists agree that you should apply a base coat (here are 15 Byrdie-approved options) first to help protect your nail bed from staining and refrain from leaving your polish on for too long.

The Final Takeaway

Some people are more prone to nail polish-induced yellowing than others, but it can happen to anyone. The more porous your nails are, the more likely it is. However, other factors can increase the chances of it occurring, like the type of nail polish, the darkness of your nail polish, and the removal process. If you do notice a yellow tint on your nail bed, rest assured you can treat it with ready-made nail care products or DIY concoctions. And, of course, if the yellow tint persists, you should visit a dermatologist or physician for their treatment advice.
