Beware! This product is dangerous! And, while customer service sounds helpful, they are not! I cancelled the order soon after receiving it... or so I thought. I continued to be billed and called customer service again to be told that it had been too long since the initial order to receive a refund or stop the order. And, the product is a scam. I did try to use it only to have my eyelids become red and scaly, and then to wake one morning with one eye swollen nearly completely closed! DO NOT use this product. I am still trying to heal my damaged lids!
