Background And Aim:
Non-surgical procedures using injectable filler products for perioral rejuvenation have emerged and evolved rapidly to become one of the most frequently performed aesthetic treatments. We report a case series describing the administration of two hyaluronic acid-based dermal fillers (HA filler) with excellent characteristics and formulation using a technique developed by the author.
Patient/Methods:
We describe a series of nine female subjects who underwent perioral rejuvenation performed by a single physician in her private clinic. The HA filler (Alaxin® FL or Alaxin® LV) was injected into the lips using the specially developed Clodia technique. Patients were given post-treatment advice for optimal results. Patient- and investigator-perceived outcomes were rated using the Global Aesthetic Improvement Scale (GAIS) and adverse events (AEs) were collected.
Results:
All subjects described the injection method as painless and well tolerated, as shown by the immediate post-treatment photographs. Mean GAIS scores for both the patients and the investigator were 4.8/5, indicating significant improvement 12 months after the treatment. No AEs were reported during follow-up. The HA filler showed a high degree of dermal integration in all subjects, and the investigator reported excellent handling and injection properties.
Conclusion:
Perioral rejuvenation with an HA filler administered using the developed injection technique gave highly satisfactory results in all subjects and was not associated with AEs.
