    Area of Science:

    • Aesthetic Medicine
    • Dermatology
    • Plastic Surgery

    Background:

    • Understanding facial anatomy and botulinum toxin A's mechanism is crucial for optimizing treatments.
    • Current injection techniques may have limitations regarding efficacy and potential side effects like ptosis.

    Purpose of the Study:

    • To introduce a new, refined injection procedure for botulinum toxin A.
    • To enhance the safety profile by decreasing risks of eyebrow and eyelid ptosis.
    • To expand the therapeutic possibilities and effectiveness of botulinum toxin A treatments.

    Main Methods:

    • Utilizing an improved understanding of facial functional anatomy and botulinum toxin A action.
    • Implementing variable toxin concentrations tailored to specific facial areas.
    • Applying the new procedure to upper face, nose, nasolabial fold, jawline, and neck regions.

    Main Results:

    • Significantly decreased risk of eyebrow and eyelid ptosis.
    • Increased possibilities and efficiencies in toxin A injections.
    • Achieved results comparable to endoscopic surgical actions in the upper face.
    • Demonstrated effectiveness in non-traditional areas like the nose, jawline, and neck.
    • Observed a skin-smoothing effect due to the anticholinergic action on dermal receptors.

    Conclusions:

    • The new botulinum toxin A injection procedure offers enhanced safety and efficacy.
    • This technique broadens the application scope of botulinum toxin A for facial aesthetics.
    • The procedure provides a valuable alternative for achieving rejuvenation with reduced side effects.
