Sally Hansen Insta-Dri Nail Polish - Pink Blink

The longevity varies, but it's designed to be chip-resistant and long-wearing. It can last for several days with proper application and care.

Yes, you can use a separate top coat for added shine and protection, but it's not strictly necessary as the polish includes a built-in top coat.

The polish has a base coat, but for extra nail protection, you can use a separate base coat before application.

Use a standard nail polish remover.

Apply one or two thin coats depending on the desired color intensity.

If the polish thickens, add a few drops of nail polish thinner, not remover, and shake well.

While the formula is designed to be gentle, if you have very sensitive nails, test a small area first to check for any adverse reactions.

Ensure you apply thin, even coats. Avoid applying too much polish at once.

Ensure you're applying thin coats and allow adequate drying time. Make sure the bottle is not old or thickened.

Ensure nails are clean and dry before application. Apply a thin top coat for added protection.

Apply two thin coats to achieve the desired color intensity and depth.
