Candles are a great way to create a cosy atmosphere, but how long do they last? The lifetime of a candle depends on several factors, such as the type of wax used, the presence of added fragrances or colours, and how it is stored. While candles don't have an expiration date, their quality can degrade over time, affecting their scent, colour, and burn time. Proper storage in a cool, dark, and dry place can help prolong a candle's life, but even with the best care, factors like scent degradation and colour fading will eventually come into play.

What You'll Learn
Candles should burn for no longer than 2-4 hours at a time
While candles can provide comfort, luxury, and relaxation, it is important to follow safety guidelines when burning them. A good rule of thumb is to limit each candle to a burn time of 2 hours, but no more than 4 hours at a time. Burning a candle for too long can cause carbon to collect on the wick, leading it to "mushroom". This will cause the wick to become unstable and produce a dangerously large flame. Additionally, your candle will start to smoke and release soot. To avoid this, always follow the manufacturer's instructions and allow the candle to cool completely before lighting it again.
The lifetime of a candle depends on the type of wax used and how it is stored. Paraffin wax candles, for example, can last virtually forever if stored properly. However, natural or organic waxes like soy and coconut may offer a more luxurious burning experience but have a shorter lifespan. To extend the life of your candle, store it in a cool, dark, and dry place, away from direct sunlight or bright indoor lights.
It is also important to note that candles can expire. While they may not pose a threat if lit past their shelf life, they may burn less evenly and lose their fragrance. Scent degradation occurs when an unlit candle gradually loses its original fragrance due to the evaporation of fragrance oil molecules. Color degradation can also occur, especially if the candle is exposed to UV light. To preserve the color and scent of your candle, store it in an airtight container and avoid displaying it in direct light.
Finally, always practice candle safety. Burning a candle to the bottom of the wick can create a fire hazard. Always manually extinguish the candle after 2-4 hours and consider using a candle snuffer instead of blowing it out. By following these guidelines, you can safely enjoy the ambient warmth and fragrance that candles provide.

Store candles in a cool, dark, dry place
While candles don't have an expiry date, their lifetime depends on the type of wax used and how they're stored. Proper candle storage is about prolonging the life of your candles and preserving the experience they offer.
When storing candles, it is best to keep them in a cool, dry, and dark place, away from direct sunlight or harsh indoor lighting. The ideal temperature is below 27 degrees Celsius to prevent overheating and scent degradation. Avoid storing them near windows, heaters, or other sources of heat and humidity. Instead, consider using a cabinet or drawer in a room with a consistent temperature.
Additionally, always keep candles upright and covered to protect them from dust and other particles. For delicate or uniquely shaped candles, use bubble wrap or a soft cloth for added protection. Avoid stacking heavy items on top of the candles to prevent warping.
Other Tips for Candle Storage
- Avoid placing candles in areas with water, moisture, or condensation, such as bathrooms and kitchens.
- Direct sunlight can cause oxidation and degradation of fragrance oils, so keep candles away from sunlight and UV light.
- Fragrance oils and waxes are sensitive to heat, so avoid storing candles near heat sources.
- Store candles away from flammable items and in a space with a consistent temperature.
- If displaying candles as decorative pieces, they may lose their colour faster, depending on the light exposure.
- When burning a candle, limit each session to no more than 2 hours and never leave it unattended.
By following these guidelines, you can maximise the lifespan of your candles and preserve their appearance, scent, and performance.

Scented candles lose their fragrance over time
While candles don't have an expiry date, scented candles do lose their fragrance over time. This is due to the breakdown of fragrance oils, which causes a decrease in scent intensity. The rate at which this occurs depends on factors such as the type of wax, the quality of the fragrance oils, and storage conditions.
Soy wax, for example, is known for its ability to hold fragrance well and release it gradually, resulting in a steady scent experience. On the other hand, paraffin wax has a stronger initial scent throw but may not last as long as soy wax. Beeswax also holds a scent well but may be less potent for strong fragrances.
To extend the life of a scented candle, it is recommended to store it in a cool, dry place away from direct sunlight. Heat, light, and humidity can cause fragrance oils to evaporate and break down more quickly, leading to a weaker scent. Therefore, it is best to keep candles in a shaded area, such as a cabinet or drawer, and to avoid temperature fluctuations.
Additionally, the lifespan of a candle depends on its size and the concentration of fragrance oils. A larger candle with a higher concentration of fragrance oils will typically last longer than a smaller candle with a lower concentration. Most candles will retain their fragrance for around 1-2 years if stored correctly, although some may last for more than a year.
To determine if a candle has lost its scent, try burning it for 3-4 hours to ensure an even wax melt and a proper fragrance release. If there is still no smell, the fragrance may have degraded over time. However, it is important to note that in some cases, you may have become "nose blind" to the scent, meaning you no longer register the smell after prolonged exposure. In this case, switching to a different candle for a while and then going back to the original one may help determine if it still has a fragrance.

Natural wax candles offer a cleaner, more luxurious experience
Candles are synonymous with comfort, luxury, and relaxation. While candles don't exactly "expire", the lifetime of a candle depends on the type of wax used and how it's stored. Natural wax candles, such as those made from soy, beeswax, and coconut wax, offer a cleaner and more luxurious experience compared to conventional candles. Here's why:
Cleaner Burn and Fewer Harmful Byproducts
Natural wax candles provide a cleaner burn with fewer harmful byproducts. Soy wax, for example, is a natural, plant-based wax made from soybean oil that is renewable and environmentally friendly. It provides a cleaner burn than paraffin wax, which is a byproduct of petroleum refining. Coconut wax is also a renewable and highly sustainable crop with excellent fragrance performance, offering a smooth and clean burn.
Non-Toxic and Healthier Choice
Natural wax candles are non-toxic and healthier alternatives to conventional candles. Beeswax, for instance, is 100% natural and renewable, produced by bees. It burns with little to no smoke or soot and naturally purifies the air by releasing negative ions. Soy and coconut waxes are also non-toxic and healthier options, free from paraffin and other harmful petroleum-based waxes.
Environmental Benefits and Sustainability
Natural wax candles have a lower environmental impact and are more sustainable. Soy wax, as mentioned earlier, is environmentally friendly and renewable. Coconut wax is also highly sustainable, as coconut trees are a renewable resource with low water use and no need for pesticides. Additionally, they absorb a significant amount of CO2 per acre annually, contributing to a reduced carbon footprint.
Artisanal Craftsmanship and Therapeutic Benefits
Natural wax candles often showcase artisanal craftsmanship and therapeutic benefits. Some brands, like Arctic Wicks, use unbleached cotton wicks coated in vegetable wax, steering clear of harmful petroleum-based waxes. Neom Organics' Real Luxury Scented Candle is another example, blending lavender, jasmine, and Brazilian rosewood for stress-relieving properties and therapeutic benefits.
Overall, natural wax candles offer a cleaner, more luxurious experience with their eco-friendly materials, non-toxic properties, and artisanal craftsmanship. They provide a healthier and more sustainable option for creating a cozy and relaxing atmosphere in your home.

Burning a candle to the bottom of the wick is a safety hazard
Candles are a great way to create a relaxing ambiance, but it is important to be mindful of the safety hazards associated with them. Burning a candle to the bottom of the wick can pose a serious safety risk.
Firstly, letting a candle burn down to the bottom of the wick can create a fire hazard. The wick can "mushroom," leading to an unstable flame that is dangerously large. This can increase the risk of the flame coming into contact with flammable objects or surfaces, potentially causing a fire. Additionally, burning the candle to the very end can overheat the bottom of the container, causing it to shatter or melt, which poses another safety hazard.
Secondly, when a candle burns down to the bottom, it may start to smoke and release soot. This can not only be unpleasant and cause a strong, undesirable smell, but it can also be a health hazard. Inhaling soot and smoke can be harmful to the respiratory system and aggravate existing conditions such as asthma.
Furthermore, burning a candle to the bottom can cause the wick to shift and come loose, especially if the metal tab at the bottom melts and causes the wick to move closer to the edge of the container. This can be dangerous as it increases the risk of the flame coming into direct contact with the container or surrounding objects.
Lastly, burning a candle for too long can affect the scent and colour of the candle. The fragrance molecules can evaporate more quickly, causing scent degradation and altering the colour of the wax. This can result in an unpleasant smell and an uneven burn, impacting the overall experience and enjoyment of the candle.
To avoid these safety hazards, it is recommended to follow the manufacturer's instructions and burn candles for no longer than 2 to 4 hours at a time. Allow the candle to cool completely before relighting, and always trim the wick to 1/4 inch before lighting to ensure a safe and enjoyable candle-burning experience.
