Nail Polish Expiration Dates: Understanding '36M' and Shelf Life

36M on a nail polish bottle means that the product is good for 36 months from the date of manufacture. This is typically referred to as the shelf life or expiration date.

It's important to note that this is just an estimated shelf life. The actual lifespan of your nail polish can vary depending on:

* Storage conditions: Exposure to heat, sunlight, and humidity can degrade the polish faster.

* How often it's used: The more you use the polish, the faster it will dry out and become unusable.

* The quality of the polish: Some brands and formulations are more prone to degradation than others.

While nail polish doesn't technically expire, it's generally recommended to use it within the recommended timeframe for the best results.
