Objectives: This presentation reviews a retrospective case study on intradermal botulinum toxin type A (BTXA) for skin lifting in a cleft lip patient with facial asymmetry. Traditionally used for chemodenervation, BTXA is now explored for intradermal applications. Using 3D imaging to assess skin lifting and symmetry improvements, we evaluate its aesthetic impact. The author will also present real-world cases applying this technique for facial and body contouring, offering insights into its clinical potential.
Introduction: Botulinum toxin type A (BTXA) is widely known for its chemodenervation effects, reducing dynamic wrinkles by targeting muscle activity. However, emerging applications have explored intradermal delivery for skin lifting and contouring. This study reviews a retrospective case involving a cleft lip patient with facial asymmetry, assessing whether intradermal BTXA can improve facial balance through skin tension modulation rather than muscle relaxation alone.
Materials / method: A cleft lip patient presenting with residual facial asymmetry underwent intradermal BTXA treatment. BTXA was delivered in microdroplet form across targeted dermal zones rather than intramuscularly. Pre and post treatment facial scans were captured using three dimensional imaging to evaluate symmetry and lifting effects. Skin surface elevation and contour changes were analyzed quantitatively and qualitatively over a defined follow up period.
Results: Post treatment analysis showed noticeable improvement in mid and lower face symmetry, particularly along the nasolabial and perioral regions. Three dimensional imaging revealed subtle but measurable lifting of the skin on the affected side. The patient reported subjective improvement in facial balance without the heavy or frozen appearance often seen with traditional dosing. No adverse effects or unintended muscular weakening were observed.
Conclusion: Intradermal BTXA may serve as a novel tool for skin lifting and symmetry correction in patients with structural asymmetry, such as those with cleft lip history. By targeting superficial dermal structures rather than muscle, clinicians may achieve refined aesthetic outcomes with minimal risk. The author will also share additional clinical cases where this method was used for facial and body contouring, highlighting its broader applications and potential role in non surgical aesthetic practice.
