Do Candles Expire? A Comprehensive Guide for Candle Enthusiasts

Share Now:


There’s a soothing charm to candles. Their captivating glow, enchanting fragrance, and the overall ambiance they create make them an evergreen addition to any home or event. While it’s easy to accumulate various candles over time, it might lead you to wonder, “do candles expire?” Surprisingly, the answer isn’t as straightforward as it seems. So, here’s what you need to know about the lifespan of candles.

Understanding Candle Expiration: Do Candles Expire or Last Almost Indefinitely?

Candles are primarily made of wax, which technically doesn’t have a strict expiration date. This may cause one to believe that candles never expire, but this isn’t entirely true. While the wax in a candle can last for a very long time, other elements like the scent and wick may not. Over time, a candle may lose its fragrance, or the wick may become harder to light.

Soy, paraffin, and beeswax are the most commonly used types of wax for candles. Regardless of the type of wax, it’s the added ingredients like fragrance oil or essential oil that may lead to the belief that candles expire. Over time, these oils can evaporate, causing the candle to lose its scent.

Factors that Impact a Candle’s Lifespan

The lifespan of a candle depends on several factors:

1. Quality of Ingredients: High-quality, luxury candles made with top-notch ingredients are likely to last longer than their cheaper counterparts. For instance, candles with synthetic oils tend to lose their scent faster than candles with natural essential oils.

2. Storage: Proper storage can also impact how long your candles last. It’s best to store your candle away from direct sunlight and in a cool, dark place to extend its shelf life.

3. Usage: Unused or unopened candles may last longer than candles frequently used. However, once lit, the burn time of a candle depends on the size of the candle and the quality of the wick.

How to Tell If a Candle Has Expired

If candles can expire, you might be wondering how to tell if a candle has gone bad. While there’s no set expiration date, there are a few signs that your candle may not be at its best:

  1. The Scent is Fading: An expired candle often smells more like wax than its original fragrance. It’s a clear indication that the oils have started to evaporate.
  2. Difficulty Lighting the Wick: An old wick can become difficult to light, which could be a sign that your candle has expired.
  3. The Candle Looks or Smells Off: If the candle wax looks discolored or the scent is off, it may be best to not use the candle.

Although candles can go bad, don’t worry. You can still use an expired candle; it just might not give you the scent throw or burn time you were hoping for.

Tips for Keeping Candles Fresh Longer

To make your candles last longer and prevent the question, “do candles expire?” from popping up too soon, here are some steps you can take:

  1. Store Candles Properly: Keep candles away from direct sunlight and heat. A cool, dry place is ideal for storage.
  2. Use Candle Lids: Candles with lids can retain their scent longer as it prevents the fragrance oil from evaporating.
  3. Rotate Your Candles: Using different candles regularly can extend each one’s life.
  4. Buy in Small Quantities: If you don’t use candles frequently, buy smaller quantities to ensure they don’t lose their scent before you get a chance to burn them.


While the wax in a candle can last almost indefinitely, candles can expire in the sense that they may lose their scent or become harder to light over time. But with proper storage and usage, you can extend the life of your candles, ensuring they’re at their best whenever you want to create that cozy atmosphere in your space.

The next time you buy candles or rediscover older candles in your home, you’ll know how to assess whether they’ve gone bad and how to keep them fresh for as long as possible.


Q: Can scented candles go bad and lose their fragrance over time?

A: While a scented candle won’t necessarily “go bad” in the way food might, it can lose its fragrance over time. This often happens when the candle is exposed to light or heat, or if it’s stored for a long time without being used.

Q: How long do candles last on the shelf?

A: Typically, high-quality soy and paraffin wax candles can last a long time on the store shelves – sometimes up to two years or more without a significant decrease in scent. However, it’s recommended to use your candle within a year of purchase for the best experience.

Q: How can I tell if my unused candle has expired?

A: If your candle has gone bad, you’ll notice that it might not smell as strong as it once did even before being lit. The color might have faded, or the wax may have bloomed, leading to a white, crystalline appearance.

Q: Is there a way to extend the lifespan of a candle?

A: Yes, proper storage can prolong the shelf life of your candles. Keep them in a cool, dry place away from sunlight. Also, keep the lid on if it came with one to prevent dust from collecting on the wax.

Q: How long does an unopened scented candle last?

A: An unopened candle can last as long as it’s stored properly. However, natural wax candles such as soy and beeswax candles may have a reduced fragrance after a year or so.

Q: Can you use an expired candle?

A: Technically, you can still use an expired candle. However, it might not produce a strong scent or burn as cleanly as when it was fresh. Also, the wax might not melt appropriately.

Q: Do different types of candle wax have different shelf lives?

A: Yes, some types of candle wax have longer shelf lives than others. For example, soy wax candles and beeswax candles are known to last much longer than paraffin wax candles. However, the scent and appearance may still change over time.

Q: What are the signs that a candle has gone bad?

A: Some signs that your candle has gone bad include a loss or change in the scent, discoloration of the wax, and changes in the texture of the wax, such as becoming crumbly or showing signs of “sweating.”

Q: Do candles lose their fragrance if not used?

A: Yes, candles can slowly lose their fragrance if they are not used, especially if they are not stored properly. It’s best to use your candles within a year for the most robust fragrance.

Q: How should you store your candles?

A: The best way to store candles is in a cool, dry place away from heat and sunlight, which can cause the wax to melt and the fragrance oils to evaporate. Storing candles in an upright position can also prevent them from losing their shape.
