This is my personal experience on this product .I had slight dark armpits so I bought this product and started using it on the recommendation of my friend .As the name suggests I expected it to lighten the skin tone under my armlits but in the contrary I noticed after using it fee times that it actually darkened my armpits insted of whitning it. I till tiday have to pay for it as I have to completely stay away from half sleve dresses and shirts that I like ti wear.
