Treat beauty seekers with scar constitution and skin infection. A person with scar constitution is not necessarily a wound. Just scratching or mechanical stimulation may form keloids, and the stimulation of strong light may also trigger the same reaction. Of course, there are very few such people, and it is not difficult to find them after interrogation. Strong light may also spread the infected focus in the irradiated area.
Why is the pimple on the ear getting bigger and bigger? This reminds me of a sentence: treat the symptoms rather than the root cause. The pimple on the ear is not as simple as surgical removal. Keloid in the ear can't be treated by simple surgery, and it will be more extensive and troublesome to treat. The guidance suggests that systematic treatment, local excision, skin grafting and radiotherapy are effective. It is best to go to a regular medical institution for this kind of operation, and remember not to be greedy and cheap, and miss the big event.
