I use this product in conjunction with Melano CC lotion. I was looking for something affordable that would prevent dark spots. Someone recommended it on social media, so I decided to give it a try. The lotion has just the right thickness and spreads easily, so I massage it into my face, neck, and décolleté as well. I only use it at night since I started using it, and I haven't had any more dark spots, so I think it's working as advertised to prevent them. I plan to buy it again.
