It would be nice if the package came with any sort of directions at all. Example: best ways to use it and what the different colors are for, the order the colors are in, yellow/white look the same and cyan and blue look the same. . I had to take screenshots from something I found online and I don’t even know if it’s true or not. I haven’t noticed a difference yet on my Face or neck and have been using it twice daily for a little over a week.
