YES! I have used it only a week, and my hyperpigmentation has basically vanished. I had many, MANY marks, and they are hardly visible, it's quite surreal. Although, my scars were fairly new, within the last 6 months. In fact, I had a brand new scar, well, scab and it is now the same colour as my natural skin. I used lemon juice prior to this, which seemed to work well, just not as fast. Maybe you should try this, as well? It does sting alot, but it is not damaging! Good luck!
