For years I have had darker under arms and I made my peace with it. I have used mitchum for the first time in my life and I have noted that my underarms are nolonger dark. They have become the same as my natural skin tone. It was accidental because I did not purchase the mitchum as its not popularly found in Malawi and thr price is a bit dearer than others. It was a gift from my UK brother who visited. But now I will be buying mitchum because its worth it.
