*Original information: OPI Nail Polish boasts about not having the toxic trio (toluene, formaldehyde, and DPB) but, it has other ingredients that aren't the greatest: camphor, which can cause nausea and dizziness if inhaled, and Benzophenone 1, which may negatively affect the endocrine system.

How Long Does Nail Polish Last? Like most products, the expiration will depend on when the polish is opened. "The shelf life of an unopened polish can last up to five to eight years, and after opening the polishes last up to two years," Ling Lin says.

Is OPI Gel Polish LED or UV? Can you use OPI gel colour with a UV light? Whether you have a UV or LED lamp, OPI GELCOLOR can be cured under both. However, an LED lamp will cure the formula much quicker than a UV lamp, and as it doesn't use UV light, it's much kinder to the skin.

Infinite Shine is OPI's 3-step process that provides a gel-like shiny, durable finish without the UV light used in the salon gel manicures.
