Need More Botox In Forehead After 6 Weeks, Shouldn't It Last Longer? Tri Valley Plastic Surgery

I am noticing some movement back in my forehead after my first round of Botox 6 weeks ago. I was expecting a time range of more like 6 months! Should I make another appointment for more now or wait until I have full movement? Is this 6 week time frame shorter than normal? Not sure the money is worth it if I have to have 20 units every 6 weeks...

Botox Length of Effect

Thank you for your question. For the majority of patients Botox generally lasts three to four months, however anywhere from two to six months is not uncommon. Botox wearing off at six weeks is a little earlier than expected and there may be several reasons for this. Receiving too little Botox or not having the Botox injected directly into the muscle belly may result in shorter lengths of effect. However, some patients will still experience shortened results despite appropriate doses and injection techniques. In our San Francisco Bay Area practice we also recommend patients try Dysport, a different brand of botulinium toxin than Botox. Although Dysport is a comparable product to Botox and some patients prefer one to the other. For best results visit the office of a Board-Certified Plastic Surgeon. I hope this helps.

Botox (onabotulinumtoxinA) is an FDA-approved neuromodulator that temporarily relaxes targeted facial muscles to reduce the appearance of dynamic wrinkles. It works by blocking the release of acetylcholine at the neuromuscular junction. Results typically appear within 3–7 days and last 3–4 months, though some patients report longer duration with consistent treatment. Common treatment areas include the glabella (frown lines), forehead, and lateral canthal lines (crow’s feet). Dosing is measured in units and varies by treatment area and muscle mass.

Board certification by the American Board of Plastic Surgery requires years of specialized surgical training beyond medical school and residency.
