How long has botulinum toxin type A been used in facial aesthetics?
Injectable wrinkle treatments containing botulinum toxin type A have been used to improve the look of moderate to severe frown lines for more than 20 years. The first FDA-approved treatment was BOTOX® Cosmetic, followed by Dysport®, Xeomin®, and Jeuveau®.
Although today’s wrinkle reducers all contain botulinum toxin type A, it’s important to know that no two treatments are alike and the doses cannot be interchanged with each other.
