While candles do not have an expiration date, their scent and quality can diminish over time. Exposure to sunlight, extreme temperatures or moisture can also affect the appearance and performance of a candle.
Proper storage in a cool and dry place will help maintain its quality for longer periods. However, it’s recommended to use candles within 1-2 years of purchase for optimal scent and burn time. So, it’s best to buy candles in packaging boxes & small batches if you don’t plan on using them immediately.
