About Dr. Tager
Dr. Mark Tager, MD is an integrative and functional medicine physician with a five-decade career spanning two worlds: half of it in integrative and functional medicine, and half in aesthetics. He describes himself as a “recovering family physician” — a clinician who learned to look past symptoms to the nutritional and lifestyle roots of how patients look and feel.
Many clinicians know Dr. Tager from his work with Reliant Technologies, where he helped bring the science of fractional photothermolysis (Fraxel) to physicians around the world, and from his presentations at major medical and aesthetic conferences. Today he is the CEO of ChangeWell Inc. and the author of Feed Your Skin: Write Your Personalized Nutrition Plan for Radiant Skin — the framework that anchors the precision nutrition guides he medically reviews in the Anti-Aging Resource Center.
Credentials & expertise
A widely respected speaker and educator, Dr. Tager has spent his career at the intersection of nutrition, skin health, and clinical practice. He openly discloses his consulting relationships with nutraceutical companies and teaches a deliberately vendor-neutral, evidence-aware framework — helping clinicians separate what the science supports from what the supplement market over-promises.
