Scar patches are effective, and this has been written into the latest scar treatment guidelines in China. The main ingredient of scar patches is silicone gel, and applying scar patches to scars will inhibit the proliferation of scar cells, thus making the scars grow more slowly and with less proliferation. In the process of using the scar patch, you should pay attention to the following two points: First, you should use the scar patch as many times as possible in a day, and it is best if you can stick it for twenty-four hours. Second, the use of scar paste should be persistent, do not use it for one month and feel that the effect is not obvious, at least three months or more. It is also important to note that scar prevention and treatment is a comprehensive, systematic and complex project. If the effect is not particularly obvious with scar stickers, you can add topical drugs, or dressings with radioactive substances, and you can also use laser to assist in the treatment.
