It IS cheap and only lasts about 4 months before it oxidizes. Keep it in a cool dark place. It is a basic formula, if you are paying for an expensive brand, you are wasting your money. You can even buy and make yourself to save lots of bucks, but I'm just not that talented. You can buy it on amazon for $24 and it is special made upon order. It makes my skin even, and complexion sort of "glow" and it helps a tiny bit with my acne.
