The ingredients include propolis and essential oils. What should I know about potential sensitivities?

Propolis is a resin-like substance collected by bees from tree buds, and it is a known allergen for some people. If you have a known allergy to bee stings, honey, royal jelly, or other bee products, you should not use this product. The essential oils (e.g., eucalyptus, lavender, mint) are included for their aromatic properties and are generally well-tolerated in the low concentrations used here, but skin or respiratory sensitivities are possible, though rare with correct external ear use. Before your first full use, it's wise to perform a sensitivity test: hold a small piece of the unlit candle against the skin inside your elbow for 15-20 minutes. If no redness, itching, or discomfort appears, it's likely safe for you to proceed. During use, if you experience any itching, a rash, sneezing, or unexpected discomfort, stop immediately. Always ensure the room is well-ventilated to avoid overwhelming aroma, especially if you are sensitive to strong scents.
