After searching and trying various acne products, this one works. It should be noted that when it comes to skincare, everyone is different. However, I would say if you've been trying to find a product to clear previous spots and prevent future ones - give this one a shot. I've been using it daily for the past few weeks and it has begun to slowly clear previous dark/acne spots and has prevented new ones coming up. Works great as a spot treatment or as a moisturizer for larger areas (chin or around nose).
