I bought my first 1 oz. many years ago and found it very helpful in helping things that don't belong under the skin for a variety of reasons (i.e. splinters, cuts, puss, and the like) . It was almost gone, and I recently took an unexpected slip down my back stairs (inside from second to first floor) and fractured my elbow. A little while after surgery there were a few places needing to let go of under the skin liguid. As always, it still is very good at the job. Thanks a lot for sending it quickly.....much improved.
