I use to have darker underarms by several shades and was always self conscious about it . but I think mine was caused by deodorant . I switched to one that was natural as oppose to . chemical idk due to some fragrance based issues it not working . Now it actually works , is cheaper surprisingly and in the past year the skin has lightened to where it all blends in without noticeable difference . edit Also am pan . Never noticed it on anyone I ' ve ever datedhad sexy time with . did date someone once who dyed their body hair , that ' s about all I noticed . I think people who DO notice such trivial things like skin pigmentation are just . sad , idk if sad is the right word . perhaps shallow ? Idk . Dark pigmentation doesn ' t bother me . I ' d also not suggest skin whiteners . They ' re very dangerous .
