Beauty Secrets Nail Polish Thinner, 4 Fl Oz (Pack of 1), Thins Nail Polish for Even Flow

Virtually* all nail polish thinners are formulated with the same two main ingredients "Ethyl Acetate" and "Butyl Acetate" and they all are going to work with most** any nail polish or varnish with few exceptions; (For those who care I go into more detail down below) However most other brands charge more for a tiny 1 oz bottle than the Beauty Secrets' Nail Polish Thinner 4oz bottle.*[Some inferior products try and substitute less costly acetone for "Butyl Acetate" which can reduce the quality or even ruin some modern polish formulations]**[The main exceptions are UV curing gels they are based on vastly different chemistry and while it might kinda work for some UV curing gels, it may just destroy othersThe other minor exception I'm aware of is some but certainly not all gel and "jelly" air dry polishes particularly the kinds of clear thick jelly polishes that are used to suspend heavy glitters, foils and HOLO materials; it's not that it will typically harm these polishes they just contain additional special thinkers that won't break down.][Details]Beauty Secrets' Nail Polish Thinner formulation consists of just three solvents: the majority of which is Butyl Acetate, & Ethyl Acetate, and Heptane a minor ingredient that helps re-dissolve linked polymers and I expect improves compatibility with some polish formulations.The main ingredients "Ethyl Acetate" and "Butyl Acetate" (E.A. & B.A.) are both organic solvents and are ALSO the main ingredients in the vast majority of all nail polishes and nail varnishes. From Chanel and Louboutin to essie, OPI and Revlon right on down to Sally Hansen, L.A. COLORS, and Wet & Wild they all use E.A. & B.A. as primary solvents. E.A. & B.A. is what makes the pigments and polymers in nail polish a liquid to begin with and E.A. & B.A. is what evaporates away when your nails dry. Likewise it's evaporating out of the bottle while its open, if the lid isn't on just so and small amounts can escape even with the lid on tight, especially if stored in warm environments;l all of which cause the polish to thicken over time. So if that's what's gone missing, that's what needs to be replaced.

Polish always seems to get thick and goopy before I'm anywhere near using it all. This works really well to thin the polish and it's easy to use. Just add a couple of drops at a time until polish is the way you want it.

Found this from a YouTuber. This really saved my nail polishes!

Works really. Came in a cardboard box without even being in a plastic bag. The box was saturated and the odor was really strong. There was still about 1/2 of the bottle remaining. Looked like the bottle was just tossed in the box and sent out.

I didn't use this to revive a totally dried up nail polish or anything, but I did have a couple bottles that had gotten thick and kind of gummy; it would apply but the coats were pretty thick and would take forever to dry all the way, like it would still be gummy a full 24hrs after application. With the addition of this product, the polish's original consistency returned, and I've been able to get those thin, quick-drying coats of polish even out of my oldest bottles. I've started mixing a couple drops into every bottle before I go about repainting my nails to prevent the dry-out in the first place which seems to be working nicely as well. Definitely recommend either way!

I tend to keep nail polish around forever. If I like a color, I don't want to have to throw it out because it got thick and unusable, so I always use this nail polish thinner to keep my polishes flowing smoothly. I've been using this product for years, but I ran out and couldn't find it locally, so I turned to Amazon and there it was! Ordered it and now my polishes are flowing like new again. And it was so well-packaged and promptly shipped that none leaked out in transit, and that is always a plus in my book. Accept no substitutions, this is the real deal and works the best out of all the polish thinners I've ever used.

Did a great job of giving my favorite nail polishes a second life. I probably use way more than the recommended amount (usually 10 drops) and I repeat this step every time I use my older crusty nail polishes. It made a significant difference in the application and feel of the polish and I’m so grateful it bought me some more time with my old faithfuls!

I love this stuff it works really well. This bottle lasted me for 7 years! I love this stuff!
