My dermatologist recommended this product to treat my Melasma. She was able to successfully treat her own Melasma. I have olive skin and nothing has helped my skin issue. I’ve used this product for 4 months and see zero difference. I will continue to use it in hopes that it will do something in time. My dermatologist says it can be a slow process. So far, it is absolutely stupidly expensive for no good reason—it doesn’t work. I’d be willing to pay a small fortune if a product would actually work. I hope others have a much better experience with Alastin, which is why I gave it more stars than it deserves.
