best not to use Tea Tree oil either. In in that manner. Once the wound is pretty much close, meaning something can be put on is, you can use this product that is real. I used it for my surgery, and all is well, no scar tissue build up. Also used it on a coworker who got his upper arm shot. Very very bad. As soon as it was closed and used this on it and was amazed at the results. As you can see, no tea tree oil
The blend is synergisticly balanced with essential oils that are specific to scar tissue and reducing scar tissue not promoting it.
It may work for you. These are professional herbalists and Aromatherapists that make the blends.
