🧴 Polish Bottle Lifespan Calculator
Wondering if that half-used bottle is still good? Pick the polish type and how long ago you opened it to see roughly how many months of usable life are left — and when it is time to replace it.
💅 Is Your Polish Still Good?
What is a Polish Bottle Lifespan Calculator?
Nail polish doesn't last forever once it's opened. This calculator estimates how much usable life is left in a bottle based on its type and how long ago you broke the seal, and flags whether to keep it, use it soon, or replace it.
Use it to declutter your polish drawer and avoid the drag and bubbling of a polish past its prime. Shelf life is a general estimate — if a bottle looks, smells, or applies wrong, replace it regardless of the date.
❓ Frequently Asked Questions
How long does nail polish last once opened?
Most regular lacquers and gel polishes stay usable for around two years after opening, base and top coats often longer, and treatment products closer to a year. These are general guidelines — storage, air exposure, and formula all matter, so always check the polish itself before relying on a date.
How can I tell if my polish has gone bad?
Trust your senses. Polish that has separated and won't blend back together when rolled, turned stringy or gloopy, gone clumpy, or developed an off, chemical smell is past its best. A bad polish drags, bubbles, and won't dry evenly, so replace it rather than fight a poor finish.
How do I make my nail polish last longer?
Store bottles upright in a cool, dark place away from heat and direct sunlight, and keep the necks clean so caps seal tightly. Avoid thinning with random solvents — use a proper polish thinner if it gets thick. Good storage can add months of life, but it won't revive a polish that has truly gone off.
