One of the best things about nail polishes is that they don’t really go bad. Although they have a shelf-life of about two years, nail polishes contain so many solvents that bacteria won’t grow in them. These solvents, however, can evaporate causing your favourite shades to dry out and get lumpy. And once that happens, you’ll have to throw them away. There are a few simple things you can do to prolong their shelf life. Here’s how:
1. Store your bottles properly: nail polishes should be stored in a dry and cool environment. Keeping the bottle in a hot place will make the polish separate.
2. Close tightly: wipe off any polish residue on the opening of the bottle. It will ensure tight closure. And remember, never leave the cap off as that will cause the solvents to evaporate more quickly.
3. Store the bottles upright: storing the bottle in an upright position will prevent the polish from separating.
