I've been using this for several years, and it's a great value product that just won't go away. It doesn't seem to lighten dark spots or have any other effects, but after a few years of use, I think it's a good product once you get used to using it. At first, I rubbed it onto the dark spots and patted it to blend, but this made the dark spots stand out. I pat the stick onto the dark spots, but don't blend it in. I pat it until the dark spots are no longer noticeable, and if there's any unevenness, I blend a little around the dark spots with my fingers. Once I apply it, I don't pat the dark spots with my fingers. That's how I make them less noticeable. When I bought it, it was Transino, so I was hoping that with continued use, the dark spots would fade, but that was a disappointment. But it's still an excellent concealer, so I think it's good. It's good not just for dark spots, but also for acne scars, redness, and pimples.
