To be realistic, there is no truly accepted treatment for scars, and all treatments have some unsatisfactory aspects. It is for these reasons that the treatment of scars nowadays is gradually becoming more and more integrated. As the name implies, a combination of existing single scar treatment methods can be used in a flexible and synergistic manner to achieve better results. The most common treatments for scarring are surgery, radiation therapy, minimally invasive (laser, radiofrequency), local injections, topical medications, etc. And there are two main modes of treatment that are more popular today: one is surgery, but it is usually applied in combination with radiation therapy; the second is conservative treatment, such as laser, radiofrequency, drug injection or topical treatment. 1.Surgery as the main treatment with radiation: If the scar is treated with surgery alone, it will recur soon, and the recurring scar may be more serious than the original one by then. Therefore, surgical treatment is usually combined with radiation therapy. The effect is better than surgical treatment alone, and there are less recurrences, but because radiation therapy has the risk of causing skin cancer, although the incidence is not very high, many people are still reluctant to choose this treatment because of this. 2.Conservative treatment, such as drug injection therapy, topical drug therapy, minimally invasive (laser, radiofrequency) therapy, or a combination of multiple treatments: The most traditional drug used for scar injection therapy is hormone, although many private hospitals do not call it hormone, but scar softening needle, but changing a vest does not mean it is not hormone. Of course there are still some very few hospitals that use Pingyangmycin, 5-fu and other such drugs for treatment, but the pain is very strong, and the effect is not much better than hormones, and there are still many side effects, so there are only very few hospitals that carry out this. Minimally invasive (laser, radiofrequency) treatment, laser is not really used to treat scars, or the effect is relatively poor. The main laser used for scar treatment is fractional laser, which is divided into exfoliative fractional and non-exfoliative fractional. Exfoliative fractional cannot be used for scars because, unlike normal scars, scars grow faster when stimulated, so they may grow faster the more they are exfoliated. Non-exfoliative fractional fractional is theoretically possible, but the effect is too weak and can be used to treat mild hyperplastic scars, but for scars that are very thick and severe, the penetration depth is not enough and the effect is much worse. Therefore, fractional laser, exfoliating or non-exfoliating, is mainly used to treat ordinary scars, or at most hyperplastic scars, but less often for treating scars with pimples. Fractional RF is a new technology recently introduced, similar in principle to laser, but with RF waves instead of light waves. The advantage is that it has both the minimally invasive nature of a non-ablative fractional laser, which does not irritate the scars as much as an ablative one, but the effect is close to that of an ablative laser, and penetrates far deeper than any laser. At the same time, compared to the light wave of laser, the RF wave is a 3D three-dimensional mesh acting as a treatment. Therefore, for scars, the fractional RF treatment is also deep enough and strong enough, and it is a 3D mesh, so the new fractional RF technology, according to our own clinical experience, can be used to treat scars. Topical medications for scars are mainly silicone preparations, but of course there are now attempts to treat scars topically with imiquimod. Generally speaking, the effect of silicone preparations is slower, while the effect of imiquimod is slightly better, but it is easier to break down, so fewer people use it. 3. The choice of each conservative treatment method for scarring. The above mentioned treatment methods, generally topical drugs are mainly used for relatively mild scars, moderate ones we now try to treat with the new fractional radio frequency, severe scars, we commonly use injections with fractional radio frequency treatment. Because of the side effects of hormones, and the number of hormone injections, the recurrence rate is also relatively high, so we generally now often cooperate with fractional radiofrequency treatment. The main reason is that one can cooperate with each other to improve the respective treatment effect and reduce the number of treatments, and the side effects of hormone treatment will be less if the number of treatments is less, and secondly, the combined treatment of different methods can also reduce the recurrence rate. However, for particularly serious scars with a very large area, it is usually more appropriate to have surgical implants with radiation therapy.
