After the procedure of Renuvion, the patients may feel the crackling noise of helium gas under the skin. The gas is neutral and harmless, and will disappear after a few days. When performed by Dr. Grossman, the patients usually have minimal discomfort. NO compression garments need to be worn and NO drains are ever used. The majority of patients can return to work in one to two days while resuming near-normal activities just 3 days later. The minimum that the patients can anticipate is 30 to 50% improvements, but some individuals experience an almost magical degree of improvement.
