I had IPL treatmemt to lighten my dark/gray underarm. However, it resulted to hyperpientation. It has been 7months after the one treatment i had and my underarm never lightemed. That is why i never went back forore treatments, which i should have supposedly done, as what i have told/read so. With mu darker underas i am scared on what to do at this point. Is there any hope for this to go back to iys original skintone?or am i doomed? Thanks.
