This product is noticeably fading hyperpigmentation on the first acne blemish I've had in years. Thank goodness I had it around when I got the breakout! I battled acne for 5 years, so it's easy for me to see that the redness for this blemish is fading faster than any I've ever seen. I apply a little dab every other night. This also works well as a whole-face vitamin C serum. The packaging prevents oxygen from making contact with the product while it is still in the tube. That plus the formulation means that the vitamin C remains stable. You can use up this product at your leisure, where with other vitamin C serums they go bad in a matter of weeks. Definitely worth the price. You'll probably want to use this one in the evening since it leaves my skin a little tacky.
