Well...there are many ways you can use to get it lighter but patience is neccesary cause it's not gonna get lighter over night ...anyways....try rubbing your arm with Colgate for 10 minutes and then after washing it of rub it again for 5 min with lemon....do that 3 times a week and you'll see the difference with in a month...you can also use baking soda...mixing it with cold water and applying it but you rarely ever find baking soda at the markets There is also a lighting Nivea lighting roller deodorant....tho am not sure if it helps or not
