Uses the same protein as Botox but is specifically formulated to reduce the appearance of moderate to severe frown lines between the eyes. It’s injected directly into the affected muscles, preventing muscle fibers from contracting when you squint or frown. Treatments are quick and relatively painless, with most patients seeing improvement as early as 3 to 4 days after treatment and maximum effect at 30 days. Results typically last up to 3 months but vary by patient.
