## Questions & Answers

**Q: How is this different from it lines serum in the white pump bottle?**
A: I’ve not used the white  bottle I’ve seen it but this particular hyaluronic acid formula I swear by.  I know it didn’t answer the difference question but I love this one.

**Q: Is this product tested on animals or is it cruelty free?**
A: It's cruelty free, I would not buy it if it was animal tested.

**Q: Says product was delivered but not in mailbox. Would like another one sent if possible**
A: If they send you another one at no cost to you, if you want then accept it. If not ask for a refund

**Q: Is the container glass?**
A: I ran out awhile ago but I'm sure it was glass. Glad you asked I forgot about it. I used it with vibrance which is absolutely fantastic. But I have noticed a difference without the bye bye lines. I'm going to reorder
