Before you decide on a nail polish thinner, it’s essential to go through the points given below so that you pick the right one.

A Helpful Buying Guide To Choose The Right Nail Polish Thinner

What Is A Nail Polish Thinner

Nail polish thinners are chemical formulas used to dilute clumpy or dried-out nail polishes and bring them to better consistency. They usually contain isopropyl alcohol, ethyl acetate, and butyl acetate, which are the primary solvents present in nail polish. So when a thinner is added to the polish, these elements act as replacement solvents. A few thinners may also contain other solvents such as toluene, acetone, and heptane. But this liquid does not work with gel nail polishes, so it would be best if you used gel thinners specially designed for gel polishes.

What Should You Look For When You Buy A Nail Polish Thinner

  • Look for a thinner that works with the nail polishes you use. Not all polish thinners are suitable for all nail polish types. Different thinners are used for regular nail polishes and gel polishes. However, if you own a variety of nail polish formulas, you could opt for a multipurpose thinner compatible with every type of nail polish, no matter the brand.
  • Whether you prefer a regular lacquer or gel polish thinner, it’s wise to go through the nail polish thinner’s ingredient list before buying. Make sure that it does not contain ingredients that could damage your nails. For instance, trace amounts of acetone in a thinner are great for thinning out polishes, but it could make your nail weak and brittle in the long run.
  • Opt for a thinner that comes with a separate or built-in dropper, which makes it easy to add the exact number of drops in the polish.

Here is how to thin nail polish while avoiding air bubbles.

How To Use Nail Polish Thinner

Step 1: Use a dropper to take 2 to 3 drops of nail polish thinner.

Step 2: Open the nail polish bottle and add the drops directly into it.

Step 3: Screw the cap back on, mix it, and let it sit for some time.

Step 4: Now, roll the bottle between your palms to blend well. Again, avoid shaking as it can cause air bubbles.

Step 5: Open the cap and check the consistency of the polish.

Step 6: If it is still thick, add a few more drops (a little at a time) and roll it between your palms again.

Step 7: Once you get a smooth and flowy polish, it’s good to use.

Step 8: You can repeat the process if necessary.

Beauty specialist Barbara Ritzman says, “Once you have achieved the desired consistency, make sure to store your polish correctly by sealing the bottle tightly and storing it upright in a cool, dry place.”

Frequently Asked Questions

Is nail polish thinner safe to use? Does it really work?

Yes, nail polish thinners are said to be safe for the nails as they contain the same solvents that nail polishes are made of. And since these solvents act as replacements to the solvents that were evaporated from the polish, we could say that it does work.

What can I use instead of nail polish thinner?

You could use rubbing alcohol (91% alcohol) or pure acetone instead of polish thinner. But keep in mind that using too much acetone on your nails could break or split them.

What do I do if my nail polish is too thick?

If your nail polish is too thick, just add 2 to 3 drops of nail polish thinner into the polish and mix it well.

Is nail polish thinner the same as acetone?

Yes, in terms of what they do (restore nail polish), they are the same, but their chemical composition is different. While acetone is a solvent in itself, a nail polish thinner contains an assortment of solvents. Moreover, acetone is mainly used to remove polish from the nails and should only be added to polish if you don’t have a nail lacquer thinner, and have no other option.

Is nail polish remover a lacquer thinner?

No. A nail polish remover is a solvent used to remove previously applied nail polish from your nails. In contrast, a nail lacquer thinner is a solvent used to revive and increase the longevity of nail polish.
