In the course of our daily consultations, we often encounter people who have cigarette scars on their bodies. There are as few as one or as many as a dozen. I asked these friends why they had left this mark on themselves. Some are branded between lovers, some are internal emotional venting, some are showing off their endurance, and some are abused ……. Some people have an indelible mark or an unrelieved knot in their heart and will think of leaving a “souvenir” in this rather special way. From a doctor’s professional point of view, smoke scars, although small in size, are a more serious type of burn scars. Under normal temperature and pressure, the surface temperature of a burning cigarette is 200°C-300°C, while the center temperature of the cigarette is as high as 500°C-800°C. Because the size of a burning cigarette butt is small, but it is still a burning object and an open flame, the temperature is very high. Cigarette burns often cause skin abscesses, tissue fluid oozing inflammation, and even ulceration and infection, causing harm to the body. The actual scab will certainly leave a scar after it heals and falls off, and this scar, if not treated, can be carried for life. After the young and frivolous age, these people mature to face the social reality, when the emotions of the hot cigarette scars have slowly subsided, the world’s eyes again and again remind themselves of that unpleasant past. Not only that, the search for a job is blocked, the relationship does not go well, do not dare to let colleagues and lovers see. Therefore, the majority of them want to get rid of the smoke scar, and this idea is getting stronger and stronger. How to get rid of “smoke scars”? Many people think of laser treatment first. According to years of clinical practice, the effect of laser scar removal is not very satisfactory. Because laser scar removal must be done at least several times, each time the recovery period is generally 2-3 months, and eventually will leave traces. Because of the long treatment period, many people often fail to do the treatment and care on time. Often, they give up in the middle of the process and give up on their work. At present, the most widely used and effective way to remove such small scars is to perform a one-time excision with super-reduced fine sutures. It is an outpatient surgery, local anesthesia, no delay in normal work life, after surgery with the correct care, the final recovery is a very thin line, the normal social distance is not obvious. It is a complete farewell to the past. Every scar is an adventure, and every repair is an easy rebirth.
