Nail polish thinner
Some of the bottles get "gunk" for lack of a better term.
When I remove all polish on my nails (getting ready for new) I have to take polish remover and clean the top, the brush and neck of the bottle. This is not all products but seems to be on Get Well, get strong and a few others

Thank you for sharing this! Buildup at the brush and neck is a normal characteristic of nutrient-rich treatment formulas, not a sign of anything wrong with the product. For best results, we recommend wiping the neck and brush with a bit of polish remover after each use and keeping the cap tightly closed between applications. Our Lacquer Refresh Nail Polish Thinner is also great to have on hand to keep consistency smooth. We're always here to help you get the most out of your LONDONTOWN routine!

Frequently Asked Questions
How do I use Lacquer Refresh Nail Polish Thinner?
Lacquer Refresh Nail Polish Thinner restores thickened nail polish in just a few drops. Add 2–3 drops directly into your nail polish bottle, close the cap tightly, and gently roll or shake the bottle to distribute the thinner evenly. Check the consistency, then add 1–2 additional drops if needed until the polish returns to a smooth, easy-to-apply texture.
For best results:
- Add only a few drops at a time—you can always add more.
- Allow the thinner to fully mix before testing the consistency.
- Use whenever your polish becomes thick, stringy, or difficult to apply.
- Store nail polish with the cap tightly closed to help slow future thickening.
Because the formula replaces evaporated solvents rather than simply diluting the polish, it helps restore smooth application while maintaining the polish's original performance.
Why does nail polish become thick over time?
Nail polish naturally thickens as solvents slowly evaporate each time the bottle is opened. Even when stored properly, exposure to air causes the formula to become more viscous over time, which can lead to streaky application, stringiness, or difficulty achieving an even coat.
Several factors can accelerate thickening:
- Frequent use and repeated exposure to air
- Leaving the bottle open between coats
- Warm storage temperatures
- Product collecting around the neck of the bottle and preventing a tight seal
Rather than replacing a favorite shade, Lacquer Refresh Nail Polish Thinner replenishes the solvents that have evaporated, helping restore a smooth, workable consistency so your polish applies more like it did when it was new.
Can I use nail polish remover or acetone to thin my polish?
No. Nail polish thinner is the recommended way to restore thickened nail polish. While acetone and nail polish remover may temporarily make polish seem thinner, they work by breaking down the polish formula rather than restoring it. Over time, this can affect color, finish, durability, and overall application. Professional nail enthusiasts consistently recommend using a dedicated nail polish thinner instead of acetone for reviving polish.
Lacquer Refresh Nail Polish Thinner is specifically formulated to:
- Restore the polish's original consistency
- Improve smooth, even application
- Extend the usable life of your favorite shades
- Preserve the integrity of the polish formula
Using a purpose-built thinner helps maintain the performance you expect without compromising the finish.
Will Lacquer Refresh work with any nail polish?
Yes. Lacquer Refresh Nail Polish Thinner can be used with most traditional nail lacquer formulas, not just LONDONTOWN lakurs. Whether your favorite polish is beginning to feel thick, stringy, or difficult to apply, just a few drops can help restore a smoother consistency and make application easier again.
It is ideal for:
- Traditional nail polish
- Older bottles that have thickened over time
- Favorite shades you want to keep using
- Polishes that have become difficult to apply evenly
Because gel polish and regular nail lacquer use different chemistries, Lacquer Refresh should only be used with traditional air-dry nail polish and should not be added to UV or LED gel polish formulas.
What makes Lacquer Refresh different from other nail polish thinners?
Lacquer Refresh does more than restore polish consistency—it also reflects LONDONTOWN's nail care-first philosophy. In addition to reviving thickened lacquer, the formula is acetone-free and infused with Florium Complex®, LONDONTOWN's proprietary blend of botanical extracts and vitamins.
Key benefits include:
- Acetone-free formula
- Restores thickened polish in just a few drops
- Compatible with most traditional nail lacquers
- Contains Florium® Complex featuring botanical extracts and Vitamin E
- Helps reduce waste by extending the life of your favorite polish
Instead of replacing old bottles, Lacquer Refresh helps keep them performing beautifully for longer.
Is Lacquer Refresh vegan, cruelty-free, and 21+ free?
Yes. Like all LONDONTOWN nail lacquers, Lacquer Refresh Nail Polish Thinner is vegan, cruelty-free, gluten-free, and formulated to LONDONTOWN's signature 21+ free standard. It is made without ingredients such as formaldehyde, toluene, phthalates (including DBP), formaldehyde resin, camphor, xylene, ethyl tosylamide, TPHP, bisphenol A, and other commonly excluded ingredients.
The formula is thoughtfully developed to revive polish while maintaining the clean formulation standards that define the LONDONTOWN collection.
When should I use a nail polish thinner?
Use a nail polish thinner anytime your polish becomes noticeably thicker or more difficult to apply. If your polish feels sticky, creates strings when you lift the brush, or no longer glides smoothly across the nail, it's usually a sign that some of its original solvents have evaporated.
Common signs it's time to refresh your polish include:
- Thick or gloopy consistency
- Streaky or uneven application
- Strings of polish forming from the brush
- Difficulty applying thin, even coats
- A bottle that's only partially full but has become noticeably thicker
