As a human we should be conscious in our body fragrance.. Body odor lessens points. No matter how beautiful, rich or famous you are, those things wont exist if your hiding rotten guava in your arm pit. This is very common to those who's involve in some heavy activities like sports, stink also appears when your nervous. We can never avoid perspiration, it occurs in our everyday lives. Taking a bath is not enough to took that bad smell away. For those who can afford try buying some deodorant and apply it after taking a bath. Make sure your armpit is dry before applying. Another remedy for that is "calamansi". I never believe that until i tried it. It really works. It keeps me odor free.
