Are Scented Candles Bad for You? What's Actually Inside Your Candle
Not all candles are made the same — and the difference is what you're breathing. A candle is really only three things: the wax, the wick, and the fragrance. Get those right and a candle is a clean, quiet pleasure. Get them wrong and you're burning petroleum in your living room.
Here's what's actually inside, what to avoid, and how to check any candle before you buy it.
The wax is 90% of what you're buying
Paraffin is a byproduct of petroleum refining. It's the default in cheap, mass-produced candles for one reason: it's the cheapest thing you can pour. It burns hotter and faster than plant wax, and it produces measurably more soot and fine airborne particulates — the black film that builds up inside the jar and settles on the surfaces around it.
Natural plant waxes — coconut, soy, rapeseed — are renewable, biodegradable, and burn cooler, slower and far cleaner. Coconut wax in particular carries fragrance beautifully but is too soft to hold its shape alone, so it's blended with soy for structure.
That coconut-soy blend is what we pour, and it costs us several times what paraffin would. It's the whole reason a BELIEVE candle isn't a AED 15 candle.
The wick matters more than people think
Look for a flat wooden wick or pure braided cotton. Some cheap candles still use a wick built around a metal core for rigidity.
Wooden wicks burn with a wider, steadier flame and give you that soft crackle, like a small fireplace. Cotton gives a taller, more traditional flame. Both burn clean — what you don't want is a stiff wire inside. You can check in ten seconds: peel back the braid at the tip of an unburned wick. Cotton or wood is what you want; a metal core is a question worth asking the maker.
Fragrance: load matters more than "natural"
Fragrance is the part most likely to give someone a headache — and it's usually not because it's synthetic. It's because it's overloaded. A cheap candle compensates for weak wax by dumping in fragrance oil, which is why some candles fill a room in thirty seconds and leave a chemical aftertaste at the back of your throat.
A candle should be noticeable, not overwhelming. Ours are blended to build slowly and hold evenly across a room.
How to check any candle before you buy
Words like "clean," "eco" and "natural wax blend" are unregulated — there's no certification behind them, and "natural wax blend" can legally be mostly paraffin. So ignore the adjectives and look for these five:
- A named wax. "Coconut & soy wax" is a real answer. "Natural wax blend" is a way of not answering.
- A named wick material. Wood or cotton, stated plainly.
- The word paraffin-free — explicitly, not implied.
- Burn instructions on the packaging. Brands that actually test their candles print the trim length and maximum burn time, because that's where you learn them.
- A traceable maker. Where it's poured, in what batch size, by whom.
If a brand won't tell you the wax and the wick on the product page, that silence is the answer.
Burn it right and it stays clean
Even the best wax will soot if you burn it badly. Four rules cover almost everything:
- Trim the wick before every burn — 5 mm for cotton, and for a wooden wick snap off the charred top so about 3–5 mm of clean wood is showing. The single highest-impact thing you can do.
- Let the first burn form a full melt pool — wax reaching the edge of the glass, usually 2–3 hours. Wax has memory; a short first burn causes tunnelling forever.
- Burn 3–4 hours maximum at a time.
- Keep it out of drafts. A dancing flame is an unstable flame, and unstable flames smoke. Move it away from the AC vent.

Frequently asked questions
Are scented candles bad for your lungs?
It depends what you're burning. Paraffin candles release more soot and fine particulates than natural plant waxes. Natural coconut-soy candles with a wooden or cotton wick burn far cleaner. Whatever you burn, keep the room ventilated — and if you have asthma, burn in a larger space or choose unscented.
Why don't BELIEVE candles use paraffin?
Paraffin is a petroleum byproduct. It burns hotter and dirtier, producing noticeably more soot and airborne particulates than plant wax, and it isn't renewable. We use natural coconut and soy wax instead — it costs several times more, but it burns cool and clean, which is the point of a candle you keep in your home.
Are wooden wick candles better than cotton?
Neither is cleaner — both burn well when properly sized and trimmed. A wooden wick gives a wider, steadier flame and a soft crackle; cotton gives a taller, more traditional flame. Our SOUL Collection uses wooden wicks. What matters is that the wick is pure wood or pure cotton, with no metal core.
How do you trim a wooden wick?
Don't cut it with scissors like cotton — once it's cool, snap or pinch off the charred black top with your fingers or a wick trimmer, leaving about 3–5 mm of clean wood above the wax. A wooden wick that's left too long will struggle to stay lit and can smoke.
What does "natural wax blend" mean on a label?
Legally, nothing specific. It's an unregulated term, and a candle labelled "natural wax blend" can be mostly paraffin. Look for a named wax and the words paraffin-free instead.
Why does my candle produce black smoke?
Usually an untrimmed wick or a draft. Trim before every burn and move the candle away from AC vents and open windows. Paraffin candles soot more than plant waxes to begin with. If a trimmed candle still smokes in a still room, the wick is oversized for the vessel — a manufacturing fault.
Is coconut soy wax better than soy wax?
For scented candles, yes. Coconut wax carries fragrance noticeably better and burns slower and cooler, but it's too soft to hold shape alone, so it's blended with soy for structure. We compare all four waxes in Coconut Soy vs Soy vs Paraffin vs Beeswax.
Are candles safe around babies and pets?
Ventilate normally and keep them physically out of reach — the burn risk is more real than the air one. Choose a clean-burning natural wax over paraffin. The exception is pet birds, whose respiratory systems are highly sensitive; vets generally advise against burning candles around them at all.
