I was taking this while changing too many other things around; hard to tell whether certain effects were due to the zinc or not.
Witch Hazel Irritated My Skin
Might work wonderfully for less sensitive skin types, so I recommend it. Personally, I may do away with toners in general. They cause me too much irritation for my skin type. :(
Worst Product Ever
Developed severe break out, skin is still healing from the scars I was left with from using this product. Will never use again.
It works well when applied once every other day or so, but can be highly irritating if used too frequently or with other acne products.
