There is no scientific evidence¹ that ear candling is effective at removing earwax from your ear canal. It has not been proven to create any suction, making this claim false. Researchers have even found that as the candle burns it can leave more wax inside your ear canal from the melting candles.
Others believe that the heat from the candle melts and softens the earwax, which falls out over the next few days. However, the temperatures produced by the candle are far too low to melt earwax and were even found to be below your body’s own temperature.²
There is also the potential for candling to cause harm instead of helping:
Some people reported having worse ear aches after using the procedure.
The candle can push your earwax deeper into your ear canal instead of removing it.
Wax from the melting candle can wind up getting into your ear canal causing a worse.blockage.
The fire or melted wax could burn you since it is so close to your face and ears.
