How long do fragrance oils last, and how should I store them?

Edited

Most fragrance oils have a shelf life of one to three years when stored properly. To maximize longevity and maintain scent quality, keep them in tightly sealed containers away from direct light, heat, and humidity — a cool, dark cabinet or storage room is ideal. Exposure to heat and light can accelerate oxidation and alter the scent profile over time. Purchasing fresher batches when possible and rotating your stock also helps ensure you're always working with fragrance oil at its best.
