Our perforation repair drops contain betaine, sodium chloride, and aloe extract. They have the ability to reduce inflammation, kill bacteria, decrease sensitivity, eliminate odors, remove dirt, and provide deep cleansing. The usage method is very simple: drop one to two drops onto the scars, bumps, and wounds twice a day to achieve the best results. They are non-irritating and, with the help of normal saline, aloe, and hyaluronic acid, promote the natural healing process of the skin.
