Which cocoa er do you like on stretch marks best?

I was using Palmer's cocoa er on my stretch marks, and when I ran out I opened up the tiny bonus tube that came along with it. Thinking it was just more of the same stuff, I was surprised when I noticed it was more of a skin color than yellow and that it said 'concentrated cream' on the front. I found that this actually worked better than the original. So, considering the long line of Palmer's products, even the cocoa er directly aimed at stretch marks, and the many other versions of cocoa er, which one have you had the best success rate with?
