Sorry you are having a few problems with your concealer.
Sometimes if you push the clicker dispenser too fast or too many times it can jam. It can be freed by either pushing it in fast and releasing it or pushing your thumb onto it and sliding it off in a way that frees the mechanism. Another way of describing it is a flicking motion. If this fails a light tap on the side of the tube can free it.
Please try the above. If that doesn't work please contact us and we'll see what we can do.
