Painting your nails can sometimes cause them to turn yellow due to the pigments and chemicals used in the polish. The yellowing may also occur due to a reaction between the polish and the natural oils on your nails, or from prolonged exposure to the chemicals in the polish. Additionally, some clear topcoats can turn yellow over time, causing the nail polish underneath to take on a yellowish hue. This discoloration is harmless and usually goes away once the new nail grows out. However, if accompanied by other symptoms, it could be a sign of an underlying health condition.

What You'll Learn
Pigments and chemicals in nail polish can cause yellowing
While yellow nails can be a sign of an underlying health condition, they are most commonly caused by the nail polish we use. Pigments and chemicals in nail polish can leave a yellow stain on your nails, especially if you frequently apply nail polish without letting your nails breathe.
Nail polish can cause nails to become yellow or discoloured due to the pigments and chemicals used in the polish. The yellowing may also occur due to a reaction between the polish and the natural oils on your nails, or from prolonged exposure to the chemicals in the polish.
Darker-coloured polishes, in particular, can stain nails due to a chemical reaction between the colourant and the nail plate. This reaction is hard to predict because it doesn't happen to everyone and with every dark polish. It can also take a few days to a few weeks to occur.
Formaldehyde, a common ingredient in nail polish, can react with the keratin protein in your nails, causing them to become brittle and yellow. It is recommended to choose lighter-coloured polishes and apply a base coat before the colour polish to reduce staining.
To prevent nail polish from causing yellow nails, it is important to let your nails breathe by taking breaks from nail polish. Applying a base coat can also help create a barrier between your nails and the polish, preventing discolouration.

Nails need to breathe
Nails are very porous, meaning they can absorb substances applied to their surface. This includes dyes and pigments from nail polish, which can leave behind a yellow stain, especially if used frequently without a protective base coat.
Leaving nail polish on for too long can dry out the nail, making it brittle and more susceptible to breakage. This creates an optimal environment for fungus, bacteria, and other harmful microbes to grow underneath the nail, increasing the risk of infection.
To prevent nail discolouration and promote nail health, it is essential to let your nails breathe by taking breaks from nail polish. Here are some tips to help your nails breathe and prevent yellowing:
- Remove nail polish after a week and go polish-free for a few days before applying a new coat.
- Use a base coat to create a barrier between your nails and the polish, preventing discolouration.
- Opt for high-quality, lighter-coloured nail polishes, as darker colours are more likely to stain.
- Avoid old or expired nail polish, as it can become thick and gloopy, making it difficult to apply evenly and increasing the likelihood of discolouration.
- Apply Vitamin E to your nails, as it is a natural moisturiser that helps prevent dryness and brittleness while promoting nail health.
By following these tips, you can help your nails breathe, prevent yellowing, and maintain their overall health and appearance.

Darker nail polishes are more likely to stain
While nail polish can sometimes cause nails to become yellow or discoloured, this is not always the case. One of the most common reasons for yellow nails is the use of dark-coloured nail polishes, which can stain nails due to a chemical reaction between the colourant and the nail plate. This reaction is challenging to predict as it does not occur for everyone or with every dark polish, and it can take a few days to a few weeks to occur.
The pigments and chemicals used in nail polish, particularly darker shades, can lead to discolouration. This yellowing may also be due to a reaction between the polish and the natural oils on your nails or prolonged exposure to the chemicals in the polish. Additionally, formaldehyde, a common ingredient in nail polish, can react with the keratin protein in your nails, causing them to become brittle and yellow.
To prevent nail discolouration, it is recommended to use a base coat before applying nail polish. A base coat creates a barrier between your nails and the polish, protecting them from staining. It is also important to allow your nails to breathe by taking breaks from nail polish and removing it after a week or so. Choosing high-quality nail polishes can also reduce the likelihood of yellowing, as lower-quality polishes are more likely to cause discolouration.
If your nails have already been stained by nail polish, there are several remedies you can try. Applying nail stain remover, vinegar, or whitening toothpaste can help lighten the stain. Additionally, choosing lighter nail polish colours and always using a base coat can help prevent further staining.
While nail polish is a common cause of yellow nails, it is important to consider other possible causes, such as fungal infections, medications, or underlying health conditions. If you suspect that your nail discolouration is due to something other than nail polish, it is recommended to consult a healthcare professional for advice and treatment.

Base coats can prevent discolouration
While nail polish can sometimes cause nails to become yellow or discoloured due to the pigments and chemicals used in the polish, there are ways to prevent this. One of the most effective ways is to use a base coat before applying nail polish. This creates a barrier between your nails and the polish, preventing discolouration.
Base coats are particularly important when using darker-coloured polishes, which can stain nails due to a chemical reaction between the colourant and the nail plate. This reaction can take a few days to a few weeks to occur and does not happen for everyone or with every dark polish. By creating a barrier, the base coat protects your nails from these stains.
Additionally, some clear topcoats can turn yellow over time, causing the nail polish underneath to take on a yellowish hue. Using a base coat can help prevent this issue as well.
It is also recommended to choose high-quality nail polishes, as they are less likely to cause yellowing than lower-quality ones. Furthermore, allowing your nails to breathe by taking breaks from nail polish is crucial. Leaving nail polish on for too long can dry out the nail, making it more susceptible to staining and increasing the risk of infection.

Old nail polish can cause yellowing
Old nail polish can indeed cause yellowing. The pigments and chemicals in nail polish can lead to discolouration, especially if the polish is left on for an extended period without allowing the nails to breathe. Darker-coloured polishes are more likely to cause staining due to a chemical reaction between the colourant and the nail plate, although this reaction is hard to predict as it does not occur for everyone or with every dark polish. Formaldehyde, a common ingredient in nail polish, may also be responsible for nail discolouration.
To prevent nail polish from causing yellowing, it is recommended to use a base coat, which creates a barrier between the nails and the polish. Allowing nails to breathe by taking breaks from nail polish is also important. It is suggested that nail polish should be removed after about a week and that nails should be left unpainted for a few days before applying a new coat. Choosing lighter colours can also help reduce staining, as can selecting high-quality nail polishes, which are less likely to cause yellowing.
Additionally, it is advised not to shake the nail polish bottle as this can cause air bubbles and potentially lead to yellowing. Instead, the bottle should be rolled between the palms to mix the polish. Using old or expired nail polish should be avoided, as it can become thick and gloopy, making it difficult to apply evenly, and increasing the likelihood of yellowing.
While nail polish is a common cause of yellowing nails, it is important to consider other possible causes, such as fungal infections, certain medications, or underlying health conditions. If nail discolouration persists or is accompanied by other symptoms, it is recommended to consult a healthcare provider.
