Anti-Yellow Nail Base Coat: How to Brighten Yellow Nails
Quick answer: Yellow nails are most often caused by dark polish staining nails that weren't protected by a base coat. Give them a break from colour, buff very gently, and use a brightening base coat so they look whiter and healthier straight away. Our pick is Pink Armour Nail Gel, whose optical brighteners make tips look whiter and nail beds look pinker.
Yellow-stained nails can make even a fresh manicure look tired. The good news: most yellowing is surface staining that grows out with time and good habits. Here's what causes it, how a brightening base coat helps, and how to use one.
What Causes Yellow Nails?
- Dark or red polish worn without a base coat. This is the most common cause.
- Smoking, which stains nails and fingers.
- Some cleaning products, hair dyes and self-tan.
- Age: nails can naturally become a little duller and more yellow over time.
If your nails are thick, crumbly, painful or changing shape, or the yellowing doesn't grow out, see your GP or a podiatrist. That can be a sign of a nail infection or another health issue, and make-up won't fix it.
What Does an Anti-Yellow Base Coat Do?
A brightening base coat does two things. It adds a protective layer between polish and your nail, so dark colours are less likely to stain. And it uses tints or optical brighteners to counteract the yellow tone, so nails look brighter as soon as it's on.

Frequently Asked Questions
Does a base coat stop nails going yellow?
It helps a lot. A base coat creates a barrier between dark polish and your nail, so pigment is less likely to stain.
How long does it take yellow nails to grow out?
Fingernails grow slowly, so it can take several months for stained nail to grow out completely. A brightening base coat helps them look better in the meantime.
Can I wear Pink Armour on its own?
Yes. It gives a soft pink, natural French-polished look on its own, or you can use it as a base under colour.
When should I see a doctor about yellow nails?
If nails are thick, crumbly, painful or lifting, or yellowing doesn't grow out, see your GP or a podiatrist.
Can I buy Pink Armour in stores?
Yes. Thin Lizzy is available at Priceline, TerryWhite Chemmart and Wizard Pharmacy stores across Australia. The range can vary by store, so the easiest way to get the full range, bundles and online deals is to shop online. See our FAQ page for stockist details.
