Treatment Effect
Treatment Results
Generally, injectable treatments for forehead lines yield noticeable results. After botulinum toxin injection, effects typically begin to appear within 3 to 7 days, reaching optimal results within 1 to 2 weeks, and lasting approximately 3 to 6 months. With hyaluronic acid injections, results are visible immediately, with duration varying by product—typically 6 to 12 months, while some long-lasting formulations can maintain results for 1 to 2 years. Repeated treatment sessions can extend the duration of results and may lead to more sustained improvement of forehead lines.
