Review (1/5): This is a sample size being sold by a third party- Don't Buy.
Don't Buy from this seller! I just read the fine print. I'm a Purity of Elements user and when I saw that the serum was priced so low, I almost clicked "buy", but then I realized that this is the sample of the product, not full size and I doubt the brand had intended this for re-sale. Great great great product. Amazing brand. But don't spend money on just a sample size.
