Hi everyone! I've been getting a lot of questions about witch hazel, and my answer has been "controversial" because there's not a lot of solid information about it, and whether or not it is good seems to depend entirely on how it is made--information to which we don't have access. If you are one of the many asking about witch hazel, give this a read: http://www.paulaschoice.com/cosmetic-ingredient-dictionary/definition/anti-irritants/witch-hazel
Until I see proof that companies can fully vouch for the components of the witch hazel they use in their products, I can't recommend the use of any witch hazel products. It's not a miracle ingredient by any means (there aren't many single ingredients that are so profoundly amazing that their negative side effects are worth the risk), so you're not missing out if you choose to abstain for the time being. Keep using it if it's your favorite thing in the world, but I can't give it my blessing unfortunately.
