Botox Cosmetic and Dysport are both FDA approved. Botox Cosmetic (Botulinum Toxin Type A), is ideal for the temporary reduction of moderate to severe frown lines between the brows in patients 18 to 70 years of age. Within 2 to 10 days patients will notice a difference. These differences may vary for each patient, but the results are very impressive. There are many benefits to choosing Botox Cosmetic, including no recovery and downtime, and typical results can last up to four months.
