My skin type is aging and acne prone, age 41, and I used this for several weeks, possible a couple of months (until the 4oz. bottle was gone.) I loved using this mixed with Earthwise Beauty’s Farizad’s Veil, which made for a lovely finish and primer under my foundation. It has a lovely fresh scent, and it sinks in very nicely, with no oily residue. It didn’t cause any breakouts, that I know of. Overall, it is a great product, and I highly recommend it for anyone!
