Use of botulinum toxin type A in first intention healing wounds has been widely adopted in order to inhibit the formation of hypertrophic scars. In this report we demonstrate the use of the toxin in a surgical wound left to heal by secondary intention, after the removal of a squamous cell carcinoma in situ by Mohs micrographic surgery in supralabial region, with good cosmetic result. Botulinum toxin acts by inhibiting the proliferation of fibroblasts, by differentiating fibroblasts and by producing type I collagen, which are the main factors responsible for the good quality of the healing process.
