I’m a 38-year-old female and I’ve only just started getting Botox injections. It has worked great for fixing the lines on my forehead, but I’ve noticed that it only seems to work for about two months. I was told that it would last more like three to four months. It’s getting too expensive. Why could my Botox treatments be lasting only two months?
Your question with regards to the longevity of Botox is a good one. Two months is certainly a short period of time for the Botox to be lasting. I wonder if the concentration of Botox that you are receiving is sufficient. Injectors dilute the Botox but you should ask your injector how many units of Botox they are injection for each treatment. I generally inject about 20-25 units of Botox for glabella lines, 10-12 units of Botox for forehead lines, and 20-22 units of Botox for crows feet. My treatments last approximately four months. Botox does loose its effect over time, but two months seems too short if you have initially responded to your Botox treatments fully.
