Do you have anything that really worked on your or your child's skin.? Please share!

We have tried Murad, various over the counter stuff and prescription stuff and so far, nothing has worked. Yesterday, I went into Walgreens and they were selling this (for a lack of a better word) Zit Zapper. It is a little device that is suppose to zap them and in 24 hours the pimple disappaers. It is called "ZENO". Has anybody tried it? If so, what do you think? Is it worth the $150? The lady at Walgreens said they were selling alot of them.
