Comparison of Effectiveness and Safety of a Botulinum Toxin Monotherapy and a Combination Therapy with Hyaluronic Acid Filler for Improving Glabellar Frown

Neurotoxins and Combination Therapies

BACKGROUND

Facial aging involves multilevel changes, extending from the skin to deep support structures. A comprehensive treatment approach targeting the many aspects of facial dynamics and architecture is often necessary to achieve optimal correction, prevent changes before they occur, and/or help highlight inherited features.

OBJECTIVE

To explore the integration of botulinum toxin type A (BoNT-A) into multimodal aesthetic treatment plans.

MATERIALS AND METHODS

This article reviews evidence supporting the combination of BoNT-A with other minimally invasive cosmetic therapies, including dermal fillers, lasers, and energy-based devices as well as with plastic and reconstructive surgeries for more controlled healing and improved scar cosmesis.

RESULTS

Combination treatment protocols including BoNT-A demonstrate higher patient satisfaction and retention rates compared to monotherapy or sequential treatments. Some guidelines for sequencing of treatments exist, but evidence is scant with certain combinations.

CONCLUSION

Integrating BoNT-A into a larger aesthetic treatment plan is crucial for achieving natural and satisfying results in facial rejuvenation. Evidence supports better outcomes when incorporating with both surgical and nonsurgical modalities. Understanding how to address anatomy over time through different aesthetic therapies together allows for individually tailored, more deeply impactful treatment plans.

Optimizing Botulinum Toxin A Administration for Forehead Wrinkles: Introducing the Lines and Dots (LADs) Technique and a Predictive Dosage Model

This study introduces the Lines and Dots (LADs) technique, a new approach for administering botulinum toxin type A (BoNT-A) in treating forehead wrinkles. (1) Background: BoNT-A application patterns in the forehead often rely solely on the anatomy of the frontalis muscle. The LADs technique proposes a combination of anatomical features with nerve pathways. (2) Methods: The technique employed a grid system aligned with the supraorbital and supratrochlear nerve pathways and used an electronic acupuncture pen for validation. This study analyzed treatment outcomes for efficacy and safety and proposed a predictive model for BoNT-A dosage. (3) Results: LADs was associated with a high satisfaction rate and low side effect incidence. The predictive model followed BoNT-A Units=0.322×Muscle Pattern Code+1.282×Line Type Code+2.905×Severity Pre-Treatment+3.947. (4) Conclusions: The LADs technique offers an alternative approach to treating forehead wrinkles, optimizing efficacy while minimizing the BoNT-A dose required.
