Will the Botox slow the healing process or cause complications to my wound? (Photo)

Botox works on suppressing muscular activity, and muscular movement around any new healing wound can lead to the formation of stretch scars. As such, Botox has actually been recommended for concomitant use around surgical incision lines to minimize the development or the extent of spread scar formation.  I routinely inject it nowadays around surgical excisions for this purpose, especially when the excisions are in areas prone to a great deal of muscular activity, such as near the shoulders. I have also not read or personally observed any negative effects on wound healing from it. So, in short, the Botox can only potentially help.

Sorry for your injury! Botox should not affect your healing, but I would not be treated again until wound is completely healed. Good luck!

The wound will heal better if there is less movement of your forehead so you are fortunate that you already have your Botox effect.

Botox should not affect the healing of your forehead wound.  The Botox partially or completely immobilizes the muscles.  It does not affect the skin or the blood supply.

While Botox will not interfere with wound healing, most injectors will forego elective injections around open skin for fear of infection.  It sounds like you had Botox prior to your cut; that shouldn't be problematic.  Without knowing how old your laceration is, you may benefit from either sutures, taping, or keeping the laceration moist now, and regular sunscreen and taping the cut after it heals.  I suggest you call a few plastic surgery practices in your area to seek further advice about your laceration, as I would argue that repairing the laceration and getting it to heal well takes priority currently; most elective laceration repairs can run the cost of a Botox treatment.  Good luck!
