Do you ever paint your nails and after the second (or third) coat notice teeny tiny little bubbles throughout your paint job? If you answered ugh, yes to the above, then read on because I have a solution for you so that you never see those dreaded little bubbles in your mani ever again.
In a nutshell, there are two categories of nail polish: quick dry formulas and gel-like formulas. Quick dry formulas are thinner (hence their short dry times) and require multiple coats to reach full opacity, while gel-like formulas are thicker in comparison so that they are opaque in one or two coats. Thicker formulas typically last longer than thinner ones and make for a better manicure, which is the tradeoff for having to wait a little longer for your polish to dry. Bubbles happen because of how you paint your nails and are no indication of formula quality, but you probably notice those annoying bubbles when you use very opaque nail polish more often than your quick dry polishes.
Bubbles in your manicure happen when you paint a thick coat of polish on your nail and then paint another polish coat overtop while the bottom layer is still drying and releasing little spouts of air through the polish. When you put a new coat of polish over a layer that is still wet and releasing air, you are trapping that air that is trying to rise through the polish and creating bubbles.
If you tend to paint your nails with thicker coats, always give your coats a little extra time to dry before adding another. Painting all ten of your nails and then immediately circling back for your second coat probably isn't enough time to let the first coat dry out enough, and you should wait 3-5 minutes before applying your second coat. Keep this in mind when you use very opaque nail polish (like Deco!) and you'll never see bubbles in your mani again. And please, don't put your nail polish in the fridge before you use it to get rid of bubbles (heard this one before) because this actually makes your polish thicker, so you will have to wait even longer for each coat to dry to give those bubbles ample time to rise to the surface.
