The Advanced Even Tone Day Night Treatment by Urban Skin Rx is a powerful serum that instantly brightens the skin and fades the look of dark spots. Taylor, the reviewer, was impressed by the product's effectiveness. The orangey brown color of the treatment caught their attention, and they applied it all over their face. They mentioned that it gives a bright and dewy appearance, but also tingles slightly upon application. Taylor noted that for first-time users, it is recommended to use the treatment once a day for a week before increasing to twice a day. Overall, Taylor expressed satisfaction with the product and plans to continue using it.
