Botulinum toxin is widely used in facial rhytide treatments. The duration of its effect’s influences treatment intervals, cost and convenience to the patient. These are key factors in successful aesthetic procedures. A review of the literature found that duration of effect was between 2 and 6 months, with most experiencing loss of maximal contraction for 3-4 months. Treatments may last between 3-4 months, and occasionally up to 6 months. No specific definition of effectiveness/ efficacy has been described and used to measure comparable end points. Additional research should help clarify the impact of brand, age, gender, ethnicity, repetition of treatment and zinc-phytase supplementation.
