The red flesh of the wound protruding out of the epidermis may be scar hyperplasia, or it may be caused by abnormal growth of tissues, which can be solved through the use of medication (tretinoin, etc.), laser treatment, and surgical treatment. 1. Medication: medication that inhibits scar growth and shrinks the scar can be applied, commonly used medications include Triamcinolone acetonide, etc. If the red flesh protrudes from the epidermis, it can be treated with laser or surgery. If the red flesh protruding out of the epidermis is small, you can also apply topical medication such as cumulonimbus cream to inhibit scar proliferation. 2. Laser treatment: If necessary, laser treatment can be carried out to reduce the scar proliferation in the red flesh area and relieve the symptoms. 3. Surgical treatment: If the red flesh protrudes more, or if the patient is keloid, then surgical excision should be considered. It is recommended that the patient consult a doctor in a timely manner to make a clear diagnosis and carry out the appropriate treatment under the guidance of the doctor, and not to use medication indiscriminately.
