Today we'll check how older bottles of OPI nail polishes look like after some years of use. First let’s repeat some general rules about storing nail polishes. They should be kept in dark and cool place, but not in refrigerator. Ideal are cooler rooms with consistent temperature, without exposing to direct sunlight. Polishes shouldn’t be near any sources of heat. Light and heat can promote color changes and fading. I just hate that some shelves in drugstores are so hot, because of heavy lightning and when you pick up a bottle it’s warm. I recently bought ruined lipstick, because it was stored on this way. I picked up 7 older polishes, they are from OPI, because this is my favorite brand and of course most of my lacquers are from them. Some are already out of use, waiting to be thrown away. One will be soon used up. Do you throw your polishes away after they’re expired? I mean after that recommended time of use, which is usual from 24-36 months, or you wait until they go bad...
