Tiny amounts are injected in and around the area. There is a stinging sensation with the procedure, which is very short lived. The procedure itself usually takes less than 10 minutes, and you can go straight back to work afterwards if needed.

Within a few days the effects start to become noticeable, although the peak of action may not occur for 1 to 2 weeks. Over a period of 3 to 4 months the effects gradually wear off and to continue the effect, repeat injections are required. Repeat injections over time may lead to longer intervals between treatments, but it is unlikely that it will ever be permanent.
