This product was recommended by my new Dermatologist as I was having allergic reactions to the over the counter Sunscreen products. It is zinc based, but per her suggestion, I ordered the tinted sunscreen so it's not so noticeable! Very effective and can be used anywhere on the face, including lips. It is a drier feeling than normal sunblock sticks, so I try to remember to apply frequently. It is a bit pricey, but I don't have to use too much for covering facial areas.
