Best Nail Polish Thinners of 2025

"Since I began using these drops, my manicures last longer and don't chip due to the thinner application I achieve. If you frequently do your nails with lacquer, this is a must-have!"

"I recently tried Orly Nail Polish Thinner and was amazed! Just a few drops revitalize my older polishes, making them apply smoothly again without changing their color or finish. This product is a money-saver!"

"This thinner is the best I've tried, quickly rejuvenating old or thickened nail polish. However, the bottle tends to leak when I dispense the drops, making it a bit messy to use."

"I bought this nail polish thinner, and it restored my old, gunky polish to almost new condition. I had previously tried cheap thinners that left an awful smell and made my polish dry poorly, but this one had none of those issues. I will stick with this brand from now on!"

"I had no idea a product like this existed! I regret throwing away so many old bottles of polish just because they became gummy. Now, I can save my favorites and keep using them!"

"This product is fantastic! I used it on thick, old nail polishes, and after adding a few drops, they were as good as new. I highly recommend it!"

"This product saved half a bottle of my favorite polish! I used a full dropper, even though the instructions suggested just a few drops. I'm planning to order two more bottles as Christmas stocking stuffers for my daughter and sister."

"I've bought this product twice, hoping it was just a one-time issue, but unfortunately, it completely dries out after use. I used it once and securely closed the lid, but when I tried to open it again, the product was completely evaporated."

"I chose this polish thinner based on the reviews, and they were spot on! I've used it several times to thin out older polishes, and it worked like a charm. My favorite polishes are like new now, though I've noticed they have a hazy look after drying."

"I absolutely love this Advance Care System! It’s fantastic! I used it, and all my nail polishes look like new! Everyone who uses nail polish should definitely have this."

"I've found this product really helpful, especially for thickened nail polish."

"I had some older nail polish, and this product revived it beautifully. It’s now easy to apply."

"I've been a huge fan of Nail Tek products for ten years. They’ve truly contributed to my long, strong nails. I’ve even introduced my young step-daughters to this passion. After spending hours painting their nails, it's frustrating when they smudge before they dry. I was skeptical about these drying drops, but I decided to give them a shot after one too many mishaps. I'm thrilled I did! I painted the girls' nails and used the drops immediately; they were able to play without ruining their polish. It feels like a small miracle! These drops are now a must-have in my nail bag!"

"I ordered this drying drops after a bad experience with another brand, but I was disappointed to find that I received only half a bottle again. How can they advertise it as 15 ml when it’s just 7.5? I expected better, especially since the drying drops work well with my favorite topcoat, Seche Vite. But, unfortunately, they don't perform well with Sally Hansen Miracle Gel Top Coat. I had to deduct a star for that reason."

"This product is like 𝓶𝓪𝓰𝓲𝓬 for my old nail polishes! Just a couple of drops bring them back to life. I’ve found it’s definitely worth the price and can fix a polish in no time!"

"This product is super easy to use! It effectively thinned out my thick gel polishes, saving me time and money!"

"I really needed this! It makes my gel polish last longer and go on smoothly."

"I've tried several brands, but this one worked better for me. Just a few drops and my gel polishes were back to normal!"

"I was thrilled to find the large 4oz bottle on sale for under $10. This product has thinned out my old polishes and even new jelly ones effectively. I was able to restore nearly dried-up glitter polishes with just a dropper full. EXCELLENT PRODUCT, EXCELLENT PRICE!"

"This product is fantastic for bringing back old, dried-up polishes without ruining them like acetone. My only issue was that the bottle arrived without a foil cap, but thankfully, nothing spilled. Just remember to store it with a tight cap to avoid evaporation issues."

"I had a few bottles of thickened nail polish, and this product worked really well for thinning them out. However, I was disappointed that no dropper came with my order, making it harder to apply."

"I've found it works really well on older, thick nail polish. Just a few drops and it’s good as new!"

"This product does exactly what it claims. I've nearly switched entirely to the kur/londontown brand."

"I was happy with Londontown products until now. I received this bottle and it was almost empty upon arrival. I tried to return it, but it wasn’t eligible for a refund. Very disappointing."

"I was really disappointed when it arrived 3/4 full; I'll never buy this again, total waste of money."

"I'm thrilled that my nail polish behaves like new now. It was definitely worth the investment!"

"The instructions suggested using 1-2 drops, but I found I needed about 10. Still, the effects were fantastic; I almost tossed some varnish, but now I can use it!"

"I was thrilled when my gel polish finally worked properly! It was previously too thick and unusable, but after adding a few drops of this thinner, the viscosity was just right. I thought the thickness was how it was supposed to be, but now it's amazing!"

"This polish thinner did exactly what I needed. After using it, my gel polishes have been curing just fine. I highly recommend it—don't hesitate to buy!"

"I was really pleased with this product! The gel polish is just like new now. I would definitely purchase it again!"
