Does body odor still exist after taking a shower?

Body odor, also known as axillary odor, is a distinctive smell caused by the interaction between sweat secreted from the axillary apocrine glands and bacteria. After bathing, the sweat and most bacteria on the skin surface are removed due to the cleansing effect, so the smell of body odor usually temporarily diminishes or disappears. The root cause of body odor lies in the abnormal secretion of apocrine glands. This secretion does not stop immediately after bathing, but rather gradually accumulates over time and interacts with bacteria again, resulting in odor. Therefore, even after bathing, if the apocrine glands continue to secrete excessively, the smell of body odor may reappear. In addition, individual differences, environmental factors, dietary habits, and other elements may also influence the severity and duration of body odor.
