Candles are a popular way to create a cosy atmosphere and are loved for their soothing aromas. But how long do they last? While some candles can last almost indefinitely when stored correctly, others have a much shorter lifespan. The lifetime of a candle depends on the type of wax used and how it is stored. For example, beeswax and paraffin candles can last a long time, whereas organic, vegetable-based waxes like soy and coconut are more prone to breaking down. Scented candles also experience gradual scent degradation, so it's best to burn them as soon as possible. Additionally, candles stored in cool, dry places tend to last longer as heat and moisture can affect their quality. Discoloration, scent loss, cracking, and uneven burning are all signs that a candle may be past its prime.
| Characteristics | Values |
|---|---|
| Scent | The scent of a candle fades over time, with the first 6 months to a year being almost unnoticeable. |
| Colour | The colour of a candle can change due to exposure to UV rays during storage, indicating that it is not fit for use. |
| Wick | The wick may become dry, clogged, or "mushroomed" due to carbon buildup, making it difficult to light and prone to producing a dangerously large flame. |
| Wax | The wax may pull away from the sides of the jar or container, becoming pitted or degraded, affecting the burn quality. |
| Storage | Store in a cool, dark, dry place, away from direct sunlight, harsh lights, high humidity, and sudden temperature changes. |
| Lifespan | The lifespan depends on the type of wax and storage conditions. Paraffin and beeswax candles can last almost indefinitely, while organic, vegetable-based waxes like soy and coconut have a shorter lifespan. |
| Burn time | Single burn sessions should last no longer than 2 hours, with a cooling period of at least 2 hours before relighting. |
| Expiry | While candles don't exactly "expire", it is recommended to use them within 12 to 16 months for the best scent and burn experience. |

What You'll Learn
Scented candles expire faster than unscented candles
The lifespan of a candle depends on several factors, including its ingredients, the type of wax used, and how it is stored. While candles do not have a conventional expiration date, they can degrade over time, and scented candles tend to expire faster than unscented ones.
Scented candles, particularly those made with natural wax and essential oils, have a shorter lifespan than unscented candles. The fragrance in scented candles can dissipate over time, especially if the candles are not stored properly. Factors such as heat, sunlight, and exposure to the air can cause the scent to weaken or disappear. Additionally, scented candles may develop an unnatural or foul odour, indicating that they are nearing the end of their lifespan.
On the other hand, unscented candles, especially those made with synthetic oils and ingredients, can be stored for years and still perform well. Beeswax candles, for example, are known for their longevity and can last almost indefinitely when stored correctly. Paraffin candles, derived from petroleum, also have a relatively long lifespan of about five years.
To maximise the lifespan of scented candles, proper storage is crucial. It is recommended to keep scented candles away from direct sunlight, open windows, and areas with high humidity or temperature fluctuations. Using a candle topper, storing them in a dark and cool place, or placing them in an airtight container can help preserve their fragrance and slow down degradation.
While scented candles may expire faster than unscented ones, it is important to note that the rate of degradation can vary depending on the quality of the candle and the type of fragrance used. To enjoy the fullest fragrance, it is generally recommended to use scented candles within 12 to 16 months of purchase.

Beeswax candles never expire
While candles do not exactly "expire", the lifespan of a candle depends on its ingredients and how it is stored. Scented and coloured candles, for instance, may spoil if left unsealed or exposed to sunlight for long periods. The scent of a candle may also weaken over time.
Beeswax candles, however, are unique in that they do not expire. They can be stored for long periods with no degradation. Beeswax candles will ''bloom' over time, which is an indication that they are pure beeswax. This bloom is a film-like substance that may appear to 'frost' the candle. Many people appreciate this frosted look, but if you do not, it can be easily polished away with a soft cloth.
Beeswax candles have even been found in sunken ships that were several hundred years old and could still burn beautifully once the wick was dried out. This indefinite shelf life is why beeswax candles are favoured by preppers and included in emergency kits.
If you want to ensure your beeswax candle lasts as long as possible, be sure to wrap it well (preferably with paper, cotton, or newspaper sheets) and store it in a cool, dry place away from light sources.

Vegetable-based candles expire faster
While candles do not have a hard expiration date, their longevity depends on the type of wax used and how they are stored. Candles made with natural wax and essential oils will not last as long as those made with synthetic oils and ingredients.
Organic, vegetable-based waxes like soy and coconut are more prone to breaking down over time. Once they start to degrade, the wick may become clogged, and the candle will be difficult to light. On the other hand, paraffin and beeswax candles are more stable and can last almost indefinitely if stored correctly.
To preserve the fragrance of a candle, it is recommended to keep it away from direct sunlight and other harsh lights. A candle topper or a glass cloche can help achieve this. Additionally, storing candles in a dark, cool, and dry place, away from areas with high humidity or moisture, is ideal.
The scent of a candle is one of the first things to degrade, and this happens gradually over time. The longer a candle is stored, the less scent it will produce when burned. Therefore, it is recommended to use a candle within 12 to 16 months of purchase to enjoy its strongest fragrance.
In summary, vegetable-based candles made with natural wax and essential oils are more prone to breaking down over time, and proper storage can help prolong their lifespan.

Proper candle storage increases lifespan
Candles are a great way to create a cosy atmosphere, and with proper care, they can last for a long time. While they don't technically "expire", their lifespan depends on the type of wax used and how they're stored.
Wax Type Matters
The type of wax your candle is made of plays a significant role in how long it will last. Organic, vegetable-based waxes like soy, palm, and coconut are more prone to breaking down over time. On the other hand, paraffin and beeswax candles are more stable and can last almost indefinitely if stored correctly. Beeswax candles, in particular, are known for their longevity, with some found in sunken ships still burning beautifully after several hundred years!
Storage Tips for Longer Lifespan
To increase the lifespan of your candles, follow these storage tips:
- Keep them away from direct sunlight and other harsh lights. Sunlight and harsh lights can cause colour degradation, making your candles look dull and faded.
- Store them in a cool, dark, and dry place. Avoid areas with high humidity or moisture, such as bathrooms.
- Avoid areas with sudden temperature changes, such as near radiators or vents.
- Use a candle topper or a glass cloche to help preserve the fragrance longer and keep dust and debris out.
- Trim the wicks regularly. This will not only improve burning but also prolong the life of your candle.
- Burn your candles within a year of unpacking them. While they may still work after this time, the scent and colour may start to fade, and the wick may become dry and clogged.
Signs of Degradation
How do you know if your candle has passed its prime? Here are some telltale signs:
- Scent degradation: The fragrance may become weaker or disappear altogether.
- Colour changes: The wax may develop an odd colour, indicating exposure to UV rays.
- Burning issues: The wick may struggle to hold a flame, or the candle may burn unevenly or not at all.
In conclusion, proper candle storage is key to increasing its lifespan. By choosing the right type of wax and following simple storage tips, you can enjoy your candles for longer and create a cosy and fragrant atmosphere in your home.

Wick maintenance prolongs candle life
While candles don't exactly "expire", proper wick maintenance can help prolong their lifespan. The type of wax used and how the candle is stored are the two main factors that determine a candle's lifetime. Organic, vegetable-based waxes like soy, palm, and coconut are more prone to breaking down over time, whereas paraffin and beeswax candles are more stable and can last almost indefinitely if stored correctly.
To ensure the longevity of your candles, it is important to trim the wicks regularly. Untrimmed wicks can lead to uneven burning, dripping, flaring, and sooting. By trimming the wick every couple of hours, you can increase the burning time of your candle by up to 25%. Additionally, allowing the candle to burn long enough for the wax to liquefy from edge to edge during each burn session will help prevent the formation of a "memory ring", which can cause tunnelling.
The type of wick also plays a crucial role in candle maintenance. Square wicks, for instance, are ideal for beeswax candles as they provide a strong flame. Cored wicks use an additional material such as paper or zinc to help the wick stay upright. Wooden wicks tend to burn hotter and faster than cotton, while 100% cotton wicks offer the cleanest, chemical-free burn.
Proper storage is also essential for prolonging the life of your candles. Store candles in a cool, dark, and dry place, away from direct sunlight and harsh lights. Avoid areas with high humidity or sudden temperature changes. Additionally, use a candle topper or a glass cloche to help preserve the fragrance for a longer period.
