Candles do not have a set expiration date, but they do degrade over time. The rate of degradation depends on the type of wax used, the presence of synthetic or natural oils and ingredients, and how the candle is stored. Synthetic candles can be stored for years, while natural wax candles with essential oils will not last as long. Scented candles have an average lifespan of 3-4 years, but proper care can extend their lifespan. Beeswax candles are known to last several years and can even be found burning beautifully in sunken ships!

What You'll Learn
Candles don't expire, but scents fade over time
While candles don't technically "expire", their lifespan depends on several factors, including the type of wax, ingredients, and storage conditions.
For example, candles made with natural wax, such as soy or coconut wax blends, tend to have a shorter shelf life compared to those made with paraffin wax. Soy candles, in particular, are best used within a year or two. On the other hand, beeswax candles are known to last for several years, even centuries, when stored properly.
The key factor influencing the longevity of candles is the scent, which can fade over time. This is due to the gradual evaporation of fragrance oil molecules from the wax, a process known as scent degradation or "scent throw". To preserve the scent, it is recommended to use candles within 12 to 16 months of purchase and to store them properly, avoiding extreme heat and direct sunlight. Additionally, burning candles for 3 to 4 hours at a time, trimming the wicks, and regularly cleaning the candles can help extend their lifespan.
While expired candles may not pose a significant threat if lit, they may burn less evenly and have a diminished fragrance. Therefore, it is advisable to pay attention to any signs of degradation, such as a weak scent or discoloured wax, and take the necessary precautions to ensure a safe and enjoyable candle-burning experience.

The lifetime of a candle depends on the type of wax and storage
The lifetime of a candle depends on two key factors: the type of wax and how it is stored. While candles do not exactly "expire", over time, the wax will lose its ability to hold scent and colour due to the natural deterioration of its organic elements.
Type of Wax
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.
Storage
Storing candles in a cool, dark place is crucial to preserving their lifespan. Fragrance oils and waxes are sensitive to heat, so keeping candles away from direct sunlight and other sources of heat, such as radiators or kitchen appliances, is essential. The ideal storage temperature for scented candles is below 80 °F (26.6 °C). Additionally, areas with high humidity or moisture, such as bathrooms, are not suitable for candle storage as they can cause the candles to degrade faster.
To protect the fragrance and colour of your candles, keep them away from direct light. Natural sunlight and harsh artificial lights can cause oxidation and degradation of the dyes and fragrance oils, leading to faster discolouration and loss of scent. Covering your candles when not in use or using a candle topper or cloche can help preserve the fragrance and keep dust out.
By choosing the right type of wax and following proper storage practices, you can extend the lifetime of your candles and enjoy their beauty and fragrance for longer.

Scented candles should be used within 12-16 months
While candles don't technically "expire", their scent and colour can fade over time. The lifespan of a candle depends on various factors, such as the type of wax, ingredients, and storage conditions. Scented candles, in particular, are best used within 12 to 16 months of purchase to ensure optimal scent and burn quality.
The scent of a candle can degrade over time, even when unlit, as the fragrance oil molecules gradually evaporate into the air. This process can be slowed down by proper storage, such as keeping the candle in a cool, dry place, away from direct sunlight and heat sources. Additionally, using a lid or cover can help retain the scent and prevent dust accumulation.
The type of wax used in scented candles also plays a significant role in their longevity. Candles made with natural wax, such as soy, coconut, or plant-based blends, tend to have a shorter shelf life compared to those made with paraffin wax or synthetic ingredients. Natural wax candles are best used within a year or two, as recommended by manufacturers and candle experts.
To further extend the lifespan of your scented candles, there are several care tips you can follow. Firstly, upon first use, it is recommended to burn the candle for a few hours to create an even melt pool and prevent "tunneling," which is the uneven melting of the wax. Trimming the wick to a length of 1/4 to 1/8 inch before lighting can also improve the burn quality and reduce soot buildup.
Additionally, it is important to allow the candle to cool completely before relighting, which can take about two hours for candles in glass containers. During the cooling process, you can reposition the wick to the wax center to prevent soot stains. Cleaning the candle of debris and charred flakes after each use can also help maintain its quality.
In summary, while scented candles may not have a strict expiration date, it is best to use them within 12 to 16 months to enjoy their optimal scent and burn performance. Proper storage and candle care practices can further extend their lifespan and enhance your overall candle experience.

Beeswax candles last the longest, even after several years
Candles do not have an expiration date, but their scent and colour can fade over time. The lifetime of a candle depends on the type of wax used, how it is stored, and its size. While paraffin candles have a lower melting point and burn quickly, beeswax candles are the most durable and long-lasting. They burn brighter, longer, and cleaner than any other type of candle.
Beeswax candles have been crafted around the globe for thousands of years. They burn at a higher temperature and are harder and denser than other types of candle wax, which makes them the perfect choice for longer-lasting candles. For example, an average 3x6 paraffin pillar candle burns for approximately 60 hours, while a beeswax pillar candle of the same size burns for more than 110 hours.
Beeswax candles also burn very cleanly when the wick is trimmed properly, producing hardly any soot. They are also hypo-allergenic, which makes them great for people with allergies or other sensitivities. Unlike paraffin candles, beeswax candles are made from a renewable resource and do not contain artificial scents or other additives, which can cause adverse reactions in some people.
Beeswax candles will also ''bloom' over time, which is an indication that they are pure beeswax. This film-like substance may even appear to 'frost' the candle, and many people appreciate this look. If you prefer a shinier appearance, you can simply polish the candle with a soft cloth.
Overall, beeswax candles are the longest-lasting type of candle, and when stored properly, they can last for several years.

How to store candles: Keep them dry, at room temperature, away from sunlight
While candles do not have an expiration date as such, they can degrade over time, especially if not stored correctly. The lifetime of a candle depends on the type of wax used, the ingredients, and how it is stored. For example, a candle with synthetic oils and ingredients can be stored for years, whereas candles made with natural wax and essential oils will not last as long.
To keep your candles in optimal condition, store them in a cool, dry place, away from direct sunlight. The ideal temperature for storing candles is between 10°C and 29°C. Keep them in a cupboard, closet, basement, drawer, or under the bed. Anywhere that is dark and cool is ideal.
Avoid storing candles in the kitchen or bathroom, as these rooms tend to have higher levels of humidity. Keep them away from windows, as direct sunlight can cause the colour to fade and the wax to melt. It can also cause oxidation and degradation of the dyes and fragrance oils in the wax, resulting in a loss of scent and colour.
If your candle has a lid, keep it covered when not in use to preserve the fragrance and keep dust out. If you have small children, it is best to store candles out of sight and reach, on a high shelf or in a cupboard.
Finally, if you have just burned your candle, ensure it is resting flat, especially if it is in a place where it might experience drastic temperature changes.
