Advanced Under-Eye & Upper-Face Filler Training for Experienced Injectors
The Natural Trough™ Technique (NTT), created by Adrienne Easterling, PA-C, is an advanced, anatomy-based approach to under-eye correction and upper-face harmonization. Unlike traditional tear trough techniques that simply “fill the hollow,” NTT focuses on root causes—fat pad descent, bone loss, ligament tethering, and facial dynamics—to restore youthful structure and achieve natural, long-lasting results.
This training also incorporates upper-face filler artistry, making it the ideal course for injectors looking to master advanced rejuvenation of the under-eye, temple, and midface. Hands-on participants will inject live models under supervision.
Recommended For: Experienced injectors with at least 3 years of practice.
Options: Observer or Hands-On (live model injection)
Includes: Didactic education, workbook, model, products (for hands-on), lunch, certificate of completion.

All of our in-person trainings are designed for injectors who have been practicing for a few years and are confident in foundational techniques—especially those participating in hands-on sessions. This ensures that each attendee has a solid understanding of facial anatomy and injection fundamentals. The recommended experience level for each course is outlined within its individual description.
