If you use the Obagi skin care line faithfully, you will definately see results. But you MUST be consistant. Twice a day. Your skin tone will even out and you will notice soft, hydrated, healthy skin. I just had lazer surgery on my face and 6 weeks later, it's recommended that I use nothing but Obagi. I love it! If you use the Clear by itself, it will eliminate the brown spots. Integrating the Retin-A will begin a mild facial peeling and speed up the fading of hyperpigmentation. But it will also make you very dry for a while (4-6 weeks at times) until your skin get past the peeling phase. Kinda like having a sunburn that peels. But the end result is well worth it.
