I've done underarm body odor surgery before, and the smell is gone. Why is there a lot of blackheads on the blade, and it stinks when it is pulled out?

This situation is generally that the odor can be eliminated after axillary osmidrosis surgery. The secretion caused by residual hair follicles should be a postoperative complication. Generally, no special treatment is required. Usually you can try to protect your skin to keep it clean and avoid irritation. You can use alcohol cotton balls to avoid the growth of blackheads. If there is no recurrence, there is no need for a second operation.
