Know your spa treatments here at Renu Day Spa. Ear candling- What is it? Ear candling is a safe, gentle, natural way to remove excess wax and debris from inside the ears. Long tapered candles are inserted gently into the ear, and then lit. The candle creates a slight vacuum effect, oxidizing, vaporizing, and drawing softened wax and debris from the ears. The warmth and smoke assists the body’s natural process to excrete impacted earwax during the day after candling is performed. The clients we attract are those who may want some relief from ear congestion due to sinus problems and those who prefer holistic methods.
