Cosmetic use of botulinum toxin type A in the elderly

Botulinum toxin type A injections are one of the most popular cosmetic procedures for diminishing the appearance of facial lines caused by habitual facial muscle contractions. Although the manufacturer’s labeling recommends botulinum toxin only for the treatment of glabellar lines among adults younger than 65 years of age, there is widespread use of the toxin for other cosmetic purposes and for patients who may be older than 65. Evidence-based safety and efficacy data on botulinum toxin use in elderly patients is limited. However, given the age-related skin changes and multifactorial causes of wrinkles in the elderly, as well as the higher risk for potential side effects due to concomitant diseases and medications, a careful risk-benefit assessment should precede the decision to use botulinum toxin in the elderly patient.
