I have been using the product for past 1 week and I have seen visible changes in my skin. Reduced pigmentation, evened skin comparatively, my stubborn marks have started to fade and white heads are under control.The only problem is packaging. With every pump some of the product is wasted as it oozes out of cap sealing. Pls improve that. I am definitely buying it again.
