Did not work for me
I used this product for the recommended 3 months period but did not see any positive results. Regarding Refund: I contacted the seller via Amazon Messaging System for refund, but got a response that it is denied since it is beyond 90 days. So, basically, the recommended period of use and warranty period are both 90 days. Not sure, how anyone can get a refund if it does not work. I feel bad for having wasted time and money.
