Cosmetic upper-facial rejuvenation with botulinum

Area of Science:

• Cosmetic dermatology
• Neuromodulation
• Facial aesthetics

Background:

• Hyperfunctional animation contributes to upper facial wrinkling.
• Botulinum toxin type A (Botox) targets acetylcholine release at neuromuscular junctions.
• This results in temporary chemical denervation, muscular paralysis, and weakness for cosmetic improvement.

Purpose of the Study:

• To evaluate the cosmetic application of botulinum toxin type A (Botox).
• To assess Botox's efficacy in improving upper facial wrinkles caused by hyperfunctional animation.

Main Methods:

• Prospective clinical study design.
• Patient selection, evaluation, and classification of animation lines.
• Injections administered to seven anatomic sites in 23 patients over 15 months, focusing on glabellar frown lines and lateral canthal lines.

Main Results:

• Significant reduction in the depth and length of glabellar frown lines.
• High patient-reported subjective improvement.
• Greater improvement in lateral canthal lines compared to inferior lateral canthal lines due to muscle anatomy.

Conclusions:

• Botox is a safe and effective method for temporary elimination of hyperfunctional upper facial muscles.
• The treatment provides significant cosmetic benefits for facial wrinkles.
• Easy-to-use modality for aesthetic enhancement.
