Area of Science:

  • Plastic Surgery
  • Dermatology
  • Ophthalmology

Background:

  • Low-positioned medial brows can contribute to an aged or angry appearance.
  • Botulinum toxin type A is commonly used for cosmetic facial rejuvenation.

Purpose of the Study:

  • To investigate the efficacy of botulinum toxin type A in elevating the medial brow.
  • To assess the potential for a 'chemical browlift' using botulinum toxin type A.

Main Methods:

  • A before-after interventional study was conducted on 30 adult patients.
  • Twenty units of botulinum toxin type A were injected into the corrugator supercilli and procerus muscles.
  • Objective measurements and subjective assessments by independent observers evaluated brow height changes.

Main Results:

  • Objective measurements showed medial brow elevation in 32% (from medial canthus) to 48% (from midpupil) of patients.
  • An increased interbrow distance was observed in 59% of patients.
  • Subjective analysis revealed that 62% of patients had higher medial brows post-treatment.

Conclusions:

  • Botulinum toxin type A injections can effectively create a chemical browlift.
  • Further research with refined patient selection criteria is recommended to optimize this cosmetic outcome.
