This product seemed appealing, but it didn't work really well for me. I followed the directions as directed. By the fourth day, I was breaking out like crazy all over the area I put the serum on. Normally, I don't have pimple issues, so I know I got them from this product. After that fouth day I never used it again. It took about five days for my face to clear up. In the meantime, I coresponded with the representatives from Zenmed. At first, the e-mails were annoying in that they kept responding with this clueless response, after I explained myself several times.
Overall, I did get my refund, which they issue you a check that comes in the mail. They have specific directions in which they want you to follow. Since, I followed them, I didn't have any problems getting a refund.
