Fox odor is generally caused by genetic factors, it is treated with topical drugs, surgical treatment, surgical treatment includes surgical excision treatment and minimally invasive surgical treatment, as well as local injection of botulinum toxin treatment. The efficacy of topical medication is relatively short, and the medication is prone to allergic reactions. Surgical treatment is more thorough and less likely to recur, but there is a fear of scarring. Minimally invasive surgical treatment is microwave and radiofrequency treatment, the treatment effect is also good, but the probability of recurrence is higher than the probability of surgery, the probability of scar formation is lower. Botulinum toxin treatment can achieve immediate results, and the side effects are relatively small, but the duration is about six months, so you need to inject once every six months.
