Nonablative laser and intense pulsed light (IPL) treatments can be safely performed immediately after botulinum toxin injections. This combination therapy does not reduce the efficacy of the botulinum toxin for dynamic rhytids.

Area of Science:

  • Dermatology
  • Aesthetic Medicine
  • Cosmetic Procedures

Background:

  • Botulinum toxin is a widely used neurotoxin for dynamic rhytids.
  • Nonablative resurfacing treatments offer minimal downtime.
  • Current practice dictates nonablative laser treatment precedes botulinum toxin injection due to inactivation concerns.

Purpose of the Study:

  • To evaluate the efficacy of botulinum toxin when nonablative rejuvenation laser or intense pulsed light (IPL) is administered immediately afterward.
  • To determine if laser or IPL treatments affect botulinum toxin's effectiveness.

Main Methods:

  • Nineteen subjects received botulinum toxin injections in glabellar or crow's-feet areas.
  • One side of the face received nonablative laser (VBeam, SmoothBeam, CoolGlide) or IPL/RF treatment within 10 minutes of botulinum toxin injection.

Related Experiment Videos

  • Photographic comparison of pre-treatment and 2-week post-treatment results.

    • Main Results:

    • No reduction in botulinum toxin efficacy was observed when nonablative lasers (VBeam, SmoothBeam, CoolGlide) or IPL/RF devices were used immediately after injection.
    • The neurotoxic effect of botulinum toxin remained consistent.

    Conclusions:

    • Nonablative lasers and IPL/RF devices can be safely used immediately after botulinum toxin injections.
    • This sequential treatment approach does not compromise the efficacy of botulinum toxin.
    • Patients can undergo these cosmetic procedures without concern for reduced treatment outcomes.
