What are the common problems with scars?

What is a scar? It is a natural and inevitable product of the repair of human tissue trauma. Can keloid scars be completely eliminated? As far as the current medical technology is concerned, once a scar is formed, even the most delicate surgical methods can only improve it, i.e., fade it, but not eliminate it completely. The main treatment methods for keloid scars Generally speaking, surgery is the main treatment method, but there is a problem of timing, only by choosing the best time for surgery can we get an optimal treatment effect, while compression, radiation and drug injection treatment are mostly used as an auxiliary treatment to surgery. In addition, keloid scars should not be treated by surgical excision alone, but by a combination of surgery and medication or radiation therapy. Specifically, the comprehensive treatment of keloid scars, which is a combination of surgical and non-surgical therapies applied together, is a common approach and general guideline in scar treatment, and is important for the treatment of all kinds of keloid scars. When is the best time for surgical scar treatment? For normal skin scar, if there is no hyperplasia, such as most of the surgical incision scar, after 6-12 months, the symptoms of congestion, pain and hardness of the scar have subsided, and the scar gradually appears to atrophy and soften. This period is the mature stage scar. For proliferative scar, the waiting time between trauma and scar treatment may be longer, usually 1-2 years, and some patients may need longer. Only after the scar is mature and softened, congestion subsides, color becomes lighter or gradually close to normal skin, and symptoms such as itching and stinging disappear, is the best time for surgical treatment; if premature surgery is blindly pursued, more bleeding during surgery If the surgery is pursued blindly too early, the bleeding will be more during the surgery, the surgical level will be unclear, the surgical trauma will be relatively large, and the possibility of re-scarring will be significantly higher after the surgery.
