Most of the body's tissues can undergo wound repair following a disruption of tissue integrity. Upon healing, these wounds result in scar formation. The scars widen when the overlying musculature pulls apart suture lines. Botulinum Toxin A (BTA) is known to prevent fibroblast proliferation and it also induces temporary muscle paralysis. Also, mesotherapy is the non-invasive transdermal injection which can aid the skin to increase collagen and elastin production. Thus, both techniques are eligible for enhancement of facial scars.
