I have seen injectors on Instagram saying it’s important to assess if someone will be prone to jowls from slimming the masseter with Botox but I can’t find any information on what would make someone likely to experience this. I am In my mid 30s. I have noticed more wrinkling in my upper face which I feel is from Botox (have gotten 4 times - 1 year and my forehead is significantly worse than before when it wear off, can’t imagine I would age that much in a year)
