Hello, I'm an expert in home goods and sustainability. Let's talk about the longevity of candles.

Candles, in general, do not have an expiration date, but they can degrade over time, especially if they are not stored properly. Here are some factors to consider:


1. Wax Type: The type of wax used in a candle can affect its longevity. Some waxes, like paraffin, are more stable and last longer than others, such as soy or beeswax.


2. Storage Conditions: Candles should be stored in a cool, dry place out of direct sunlight. Heat and light can cause the wax to break down, and the colors to fade.


3. Fragrance and Dye: If a candle is scented or colored, the fragrance oils and dyes can degrade over time, which may affect the candle's performance and appearance.


4. Wick Integrity: The wick should be kept dry and straight. A bent or damaged wick can cause the candle to burn unevenly or not at all.


5. Usage: How a candle is used can also impact its lifespan. It's best to burn candles for no more than 3 to 4 hours at a time to avoid excessive heat buildup and to ensure a clean, even burn.


6. Age: While there's no specific expiration date, candles that are very old may not burn as well as newer ones due to the degradation of the wax and other components.

In conclusion, while candles don't go "bad" in the traditional sense, their quality can decline over time, especially if they are not stored or used properly.
