Summer is approaching, and for those troubled by 'body odor,' this may be the most difficult season of the year. Raising your arms, sweating, taking crowded buses, going to the gym... that faint yet persistent smell always makes people unconsciously shrink their arms, afraid that others will notice. To get rid of this smell, many people have tried antiperspirants, body sprays, herbal applications, and even folk remedies, but the effects are often not long-lasting. And when surgery is mentioned, there are concerns: 'I heard that you have to cut off a large piece of underarm skin, which will leave a very ugly scar. What if it recurs?' The good news is that there is now a 'cross-disciplinary' technology being applied to treat body odor—it was originally a core technology for hair transplant surgery, called Follicular Unit Extraction (FUE). Using it to treat body odor not only causes minimal trauma but can also cleanly remove underarm hair at the same time.
