Was skeptical about the size and quantity of the product I received. Applied as directed and waited a day to wipe off. The spots in the shade didn’t really make a difference BUT when I checked the spot in the sun it was like magic. Directions said it may take 3 treatments. Each treatment removed more and more until the pink was GONE! UV rays are an important ingredient. Now to apologize to my daughter it wasn’t her pink towel causing me problems.
