Each candle from the collection Les Mondes de Diptyque is an exceptional product requiring particular care and attention. To enjoy your candle to the fullest: The first two times the candle is lit, let it burn for at least 5 hours each time until all the wax has become liquid on the surface. This will prevent the wax from hollowing out and forming a well around the wick. Use a candle snuffer to extinguish the candle. This will prevent the hot wax from splattering. To ensure that the candle burns evenly, recenter the wick using the wick trimmer once the candle has been extinguished and while the wax is still liquid. Regularly trim the wick with the wick trimmer (ideal length 3 to 5 mm) to avoid candle smoking or overheating.
