I have severe atopic dermatitis, and my dermatologist recommended this cream to prevent aging, since my condition prevents me from using just any product. I tested it on a small area for a week and had no allergic reaction, so now I'm using it on my face. I feel like it moisturizes for hours, and it's concentrated, so a small amount covers my entire face. The box arrived slightly damaged, but the contents were not; I suppose the fault lies with the shipping company.
