Candles do not have a hard expiration date, but their quality does degrade over time. The lifespan of a candle depends on its ingredients and how it's stored. Synthetic candles can be stored for years, while natural wax candles with essential oils will not last as long. Scented candles can lose some of their fragrance over time, and the colour may fade. The best way to store candles is in a cool, dark place, away from direct sunlight and harsh lights.

Candles don't have a hard expiration date
The type of wax used in a candle is one of the most critical factors in determining its longevity. For example, paraffin wax candles can last almost indefinitely when stored properly, while soy, coconut, and other natural wax candles have a shorter shelf life of around one to two years. Beeswax candles are also known for their longevity and can last several years in storage.
The ingredients used in candles can impact their lifespan. Candles made with synthetic oils and ingredients can be stored for years without significant degradation, while those made with natural wax, essential oils, and fragrance oils may have a shorter shelf life. The fragrance in candles can gradually evaporate over time, resulting in scent degradation. This process can be slowed down by proper storage, such as keeping candles in a dark, cool place away from direct sunlight and humidity.
Colour may also fade over time, especially in coloured candles. Additionally, candles may develop a "'bloom," a frosty white appearance on the outside, which does not indicate expiration but can affect their aesthetics.
While candles may not have a definitive expiration date, it is recommended to use them within 12 to 16 months of purchase to ensure the best scent, burn, and overall experience. Older candles may still be safe to burn, but they may not perform optimally and may not offer the same luxurious experience as when they were fresh.

Scented candles lose fragrance over time
Scented candles do lose their fragrance over time, but the rate at which this happens depends on several factors. The first factor is the type of wax used in the candle. Soy wax, for example, is known for its clean, slow burn and holds fragrance well, releasing it gradually. Paraffin wax, on the other hand, has a stronger initial scent throw but may not last as long as soy wax. Beeswax is naturally aromatic but may be less potent than soy or paraffin for strong fragrances.
The second factor is the quality of the fragrance oils used. High-quality fragrance oils are essential for scent longevity. Cheaper oils may evaporate or lose potency more quickly, while quality oils maintain their strength for longer periods.
The third factor is storage conditions. Proper storage is key to preserving a candle's scent. Candles should be stored in a cool, dry place away from direct sunlight. Heat, light, and humidity can cause fragrance oils to degrade and the scent to fade more quickly. To prevent this, candles should be stored in a shaded area, away from direct sunlight, as UV rays can degrade the fragrance oils. Additionally, using a candle topper or storing candles in an airtight container can help to preserve the fragrance for longer.
The fourth factor is the age of the candle. Most candles generally last around 12 to 16 months when properly stored, and it usually takes more than six months to a year for the scent to start fading. However, with proper storage and care, the scent life of candles can be extended beyond this timeframe.

Beeswax candles never expire
While candles do not have a hard expiration date like food, they can degrade over time. Scented candles, for instance, may lose their fragrance, and coloured candles may fade. However, beeswax candles are unique in that they do not expire.
Beeswax candles are known for their longevity and ability to withstand the test of time. Unlike other types of wax, such as soy or palm wax, beeswax candles do not go rancid. In fact, beeswax candles are so durable that they have been found to burn beautifully even after being submerged in sunken ships for several hundred years. The only maintenance required is to ensure that the wick is intact and dry.
The reason beeswax candles never expire is due to the natural properties of beeswax. Beeswax contains bee pollen and propolis, which have preservative effects. Propolis, in particular, has been used since ancient times for its ability to preserve, even in mummification. This natural preservative quality of beeswax ensures that candles made from it can last for extended periods without degradation.
While beeswax candles themselves do not expire, their appearance may change over time. A natural process called "blooming" can occur, where a film-like substance forms on the candle, giving it a frosted look. However, this blooming is considered desirable by many and is even sought after as an indication of pure beeswax. If one prefers a shinier appearance, the candle can be easily polished with a soft cloth to restore its original lustre.
In summary, beeswax candles stand out in the candle market for their indefinite shelf life. Their exceptional durability, attributed to the natural preservative properties of beeswax, makes them a reliable choice for those seeking long-lasting illumination. With proper wick maintenance and storage in a cool, dark place away from humidity, beeswax candles can provide a beautiful flame for years, if not centuries, to come.

Paraffin candles can last indefinitely
Candles do not have an expiration date, but their quality can degrade over time. The lifespan of a candle depends on the type of wax used and how it is stored. Paraffin candles, for example, are extremely stable and can last almost indefinitely when stored properly. Paraffin wax is a low-grade petroleum wax commonly found in lower-priced candles.
The first type of degradation that occurs in a candle is usually scent degradation. This happens because fragrance oil molecules slowly but constantly evaporate from the wax into the air, even when the candle is not burning. This process can be slowed by storing candles in a dark, cool place, away from direct sunlight and other harsh lights, and by using a candle topper or a glass cloche.
The colour of candles can also fade over time, and natural wax candles with essential oils will not last as long as those with synthetic oils and ingredients. Candles made with natural soy or coconut wax blends, for instance, tend to have a slightly shorter shelf life than paraffin candles. Beeswax candles, on the other hand, can last several years in storage, although they may develop a "'bloom'" that makes them appear frosty white on the outside.
While candles can be safely burned even after several years, the worst outcome of using an old candle is that its fragrance will be weakened, and the colour may be less attractive. To get the best scent and burn from a candle, it is recommended to use it within 12 to 16 months of purchasing it.

Natural wax candles expire faster
Candles do not have a hard expiration date, but they do degrade over time. The lifetime of a candle depends on the type of wax used and how it is stored. Natural wax candles, such as those made from soy, coconut, and other organic materials, are more prone to breaking down over time. These candles typically last between one to two years when unburned and should be used within this timeframe. Like all natural products, the organic elements in natural wax candles are derived from plants and other natural resources, which eventually deteriorate with time.
As natural wax candles age, they may experience scent degradation, where the fragrance of the candle gradually weakens or dissipates. This occurs because the molecules of fragrance oil slowly evaporate from the wax into the air, even when the candle is not burning. Additionally, natural wax candles can undergo colour degradation, with bright colours fading or changing over time. Exposure to sunlight can accelerate this process, as natural sunlight can cause chemical reactions within the wax due to harmful UV rays.
To extend the lifespan of natural wax candles, proper storage is crucial. These candles should be kept in a cool, dry, and dark place, away from direct sunlight and other harsh lights. Storing them in a sealed container or using a candle topper can help preserve the fragrance for longer. It is also important to avoid areas with high humidity and moisture, as well as extreme temperatures, as these conditions can interfere with the candle's fragrance and the consistency of its wax.
While natural wax candles expire faster than those made with synthetic waxes, proper storage can help delay their expiration. By following these storage guidelines, you can ensure that your natural wax candles remain usable and fragrant for as long as possible.

Frequently asked questions
Candles do not have a hard expiration date, but their quality can degrade over time. The first type of degradation to occur in a candle is usually scent degradation, where an unlit candle gradually loses its original fragrance.
The lifespan of a candle depends on what it is made of. Candles with synthetic oils and ingredients can be stored for years and still work fine, while candles made with natural wax and essential oils will not last as long.
Check the candle's cold throw (the fragrance of an unlit candle), if it's hard to detect, gently scratch the surface and if it still doesn't smell, it may be past its prime. Observe the candle's colour, if it has faded or changed, it is likely old. Also, check for dryness and yellowing.
Keep candles away from direct sunlight and other harsh lights. Use a candle topper or a glass cloche to preserve the fragrance longer. Store candles in a dark, cool, dry place and avoid areas with high humidity, moisture, or sudden changes in temperature.
