I heard very good things about this roll on so I decided to buy it, but it caused so much itching in my underarms everytime I used it and it made my underarms very dry and I used to itch them all the time.i dont like this product at all.Maybe this product is not suitable for all skin types.
I stopped using it after 3-4 uses .I can not say whether it makes your underarms fairer or not but it made mine worse.I would not recommend sensitive skin people to use it.
