It is difficult for drugs to be effective after being injured for so long. Generally, it is almost ineffective for more than half a year. You can only do surgery to smooth the hyperplastic tissue, and remember to use medicine after surgery (you can use medicine on the new wound after surgery, but you can't break the wound yourself to avoid aggravation), otherwise the scar can't be removed. General drugs should be used after a week of wound healing, and some drugs should be used when the wound is not healed. Such as basic fibroblast growth factor. "People" is the best, but the reorganization is not very good. However, hospitals generally give "Befuji" (recombinant bovine basic fibroblast growth factor), and hospitals rarely give "human basic fibroblast growth factor".

Fibroblast growth factor is used when the wound is not healed (its own medicinal purpose is to make cells proliferate, so as not to be infected by bacteria too slowly). After the wound is healed, drugs should be used to prevent proliferation (the cells of skin are blind, while the cells of adult skin grow slowly, but grow well-but still grow, which will cause scars, so it is necessary to artificially-regulate their growth with drugs).

In the easy-to-understand place of thread tying, it is also necessary to stick a special silicone film for wounds to avoid scars left by activities. And this place is easy to get oil, easy to get oil or dry skin is easy to leave scars. Pay attention to changing the silicone membrane frequently, and use oil-absorbing paper specially to absorb wound grease.

Don't be afraid of trouble, after all, it hurts your face. I suggest you have an operation quickly. The earlier the operation and nursing are performed, the higher the chance of recovery. The longer the scar remains, the more serious the skin tissue alienation and the more difficult the treatment is.
