Nayelly Karlstromer A.Verified PurchaseHave been using this since roughly August 30th and it is now Sep 27. The difference in my dark armpits is noticeable. The lighting is slightly different since one was taken in the day the other at night but it is still obvious there has been some lightening. Will update for a review of my groin area for which I am also using this treatment for. Helpful14 found this helpful
