OBT Optical Beam Therapy VIP Certification Exam

OBT — The Optical Beam Therapy (OBT) Certification is a professional credential in laser and light-based aesthetic therapy, aligned with ANSI Z136 laser safety standards and competency frameworks established by laser safety organizations such as the Laser Institute of America (LIA) and the National Council for Laser Certification (NCLC); no single universal standardized exam body governs all OBT credentialing, so this is an original comprehensive practice set mirroring the core domains typically assessed.
