Your skin doesn't look bad.
Consider that your skin will look like shit for the first and possibly second month of the regimen....
If you've already done the work it might not be worth it to switch, but then again the regimen seems to be taking longer for me than it does for other people.

As far as the cost, I think when you break it down at a cost per oz you will see that it isn't that expensive. Though I must admit that the shipping cost should be reduced.
