16. What are the risks if mole removal is performed by practitioners without medical training?
除痣／點痣當然有風險／危險。操作者如果沒有醫學常識／醫學訓練，脫墨傷口可能會流血，如果流，血操作者亦未必懂得止血。若果操作者沒有醫生牌，他／她連麻醉膏也不能用。如果他／她使用有效的麻醉膏，已經犯法。
在香港，麻醉膏屬於第一部毒藥。根據《藥劑業及毒藥條例》，只有註冊醫生（或從註冊藥劑師監督下的獲授權毒藥銷售商（即藥房））可以取得並使用含量高於 0.7% 的麻醉膏，違例者最高可罰款一萬元及監禁兩年。（注：平常使用的麻醉膏5%或以上）。
沒有正式醫學訓練就可能沒有無菌知識，操作儀器如果消毒不徹底，就可能會引致傷口感染，引致疤痕形成。
就算儀器乾淨無菌，如果沒有醫學知識胡亂把墨痣切除，可能會切到大血管（例如頸大動脈），引致流血不止，會有生命危險。如果不小心又可能會切到大神經（例如面神經，三叉神經），引致面癱。施手術者可能會被控無牌行醫。
總結：未經醫生使用麻醉膏即屬違法，過程亦可能誤傷大血管與神經。擁有臨床與美容雙學歷認證的醫生能保障病人的安全與美感，非醫療人員不具合法與技術基礎。
Bleeding: An untrained person may not even know how to stop active bleeding during or after the procedure.
Anesthesia concerns/risks: In Hong Kong, topical anesthetic creams are classified as Part 1 poisons. Under the Pharmacy and Poisons Ordinance, only registered doctors (or licensed pharmacists under supervision) may obtain or use anesthetic cream with medical grade concentration. Using them without authorization is illegal and may result in a HK$10,000 fine or up to two years in prison. Overdose of topical anaesthesia (eg lidocaine), in severe cases, includes muscle tremors, seizures, respiratory depression, unconsciousness, coma, and cardiac depression.
Infection risk: Without sterile technique, improper tool handling can lead to wound infection and scarring.
Severe injury: Even with sterile instruments, an unqualified person might accidentally cut a major artery (e.g., carotid artery), causing unstoppable bleeding—or sever a major nerve (e.g., facial nerve, trigeminal nerve), potentially resulting in facial paralysis.
Illegal practice: Performing medical procedures without a license may result in criminal charges for practicing medicine unlawfully.
Conclusion: From anaesthesia toxicity to illegal practice—mole removal by non-medicals is a minefield. Your safest path is with a registered doctor qualified in both dermatology and aesthetic medicine, who knows what they’re doing and does it legally.
