My glabella and forehead both need botox. How many units would I need to have a natural looking forehead? (Photo)

An injector typically injects the minimum amount of Botox initially. Botox takes 2 weeks to completely settle. After the 2 weeks you can schedule a follow up appointment to administer additional units if required. The line across your forehead may require a filling product in order to soften the line to desired look. All the Best

Fanonlyaa  Thank you so much for your photograph.  While it is helpful a complete exam is necessary to know your best course of action.  Botox works by diminishing the strength of the muscle that has caused the wrinkle.  The muscle we see on you is the frontalis but if we weaken this alone you are at risk of having your entire eyebrow fall.  an expert injector needs to see all the surrounding muscles inaction to balance your upper face and give a natural result.  May are under the false belief that anyone can inject Botox but it is very technique dependent.  You have also lost volume in your forehead and this has caused this major wrinkle.  I would suggest a combination of filler with the botox.  My favorite filler to achieve this is artefill.  I  have been injection Botox for two decades and I am nationally certified Artefill injector.  I would be more than happy to give you a complimentary consultation.
