"I saw Ambi Skincare Fade Cream recommended by a dermatologist on BuzzFeed, and figured I’d give it a shot, and WOW. After a month, my dark spots had faded dramatically, and after three months they’re nearly gone. It has SPF to help prevent further sun damage, it’s super-lightweight, the tube lasts forever, and they even make an oily-skin version that has a slight mattifying effect and won’t aggravate acne." —TheIrishCowgirl
