Yellow nails: causes, treatment, and prevention
Yellow nails are common. Sometimes they are mainly a cosmetic issue, but they can also reflect your health. Below you’ll read about the causes, how to treat discoloration, and what you can do to prevent it.
Yellow nails from nail polish
Dark nail polish can leave yellow stains on your nails. The pigments penetrate the top layer of the nail. Especially if you polish often without breaks, the discoloration becomes more noticeable. This yellow color usually grows out on its own.
Yellow nails from smoking
Smoking can cause yellow nails. Nicotine and tar absorb into the skin and nail. This not only leads to discoloration but can also be a sign of broader damage to the body.
Medical causes
For some people, yellow nails are a symptom of a medical condition. In liver problems, waste products may build up in the body, visible as nail discoloration.
Yellow nails are also common in people with diabetes. The cause is often reduced blood circulation or an increased risk of infections. In people with lung conditions such as “yellow nail syndrome,” nails are not only yellow but also thick, curved, and slow-growing. This syndrome may occur together with breathing problems or fluid buildup.
Sometimes medications or a fungal infection (onychomycosis) cause yellow nails. If in doubt, medical evaluation is needed.
Treatment of yellow nails
There are several ways to address surface discoloration. Lemon juice can help lighten mild stains. Whitening toothpaste may also work, especially for nail polish-related discoloration.
A diluted solution of hydrogen peroxide is sometimes used, but be careful because of the risk of skin irritation. Baking soda can help gently clean the nail surface, particularly in mild fungal cases.
Other helpful steps
Quitting smoking is important if that’s the cause. Always use a base coat under nail polish to prevent staining. Care for your nails with nourishing oil to keep them healthy and reduce discoloration. Consider our Nail Treatment Bottle to help permanently address discoloration.
Prevention of yellow nails
Yellow toenails are often caused by fungal infection. Practice good hygiene, keep feet dry, and wear breathable footwear.
Want to prevent discoloration from nail polish? Use a base coat and give your nails occasional breaks. Remove polish gently and avoid harsh products such as pure acetone.
Nutrition and nail health
For healthy nails, you need enough biotin, iron, zinc, omega-3, and vitamin E. Deficiencies can lead to brittle or discolored nails. Only use supplements when necessary, and always in consultation with your doctor.
When to see a doctor
Contact your doctor if the discoloration persists despite proper care. Also see a doctor if you experience pain, swelling, or if your nail changes shape. If you also have other symptoms such as fatigue or shortness of breath, further examination is needed.
In summary
Yellow nails are usually harmless, but sometimes they can point to something more serious. Take good care of your nails, stay alert to other symptoms, and consult a doctor if in doubt. This way you prevent a small signal from masking a bigger problem.
If you notice that discoloration keeps returning, it may help to use a care product specially developed for fragile or damaged nails. A simple daily routine with the right pen can make a difference in the long term. Take a look at our Nailcare Pen to ensure discoloration doesn’t stand a chance.
