What Does an Anti-Aging Doctor Do? A Physician's Guide
By Charles Kamen, MD, board-certified neurologist
An anti-aging doctor — more accurately, a longevity or healthspan physician — practices evidence-based medicine aimed at extending the years you spend healthy and functional, not at "reversing" aging. The honest starting point is this: no treatment reverses aging, and any clinic promising a fountain of youth has left medicine. What a real anti-aging physician does is measure your biology, identify what is genuinely off track, and apply interventions that the evidence actually supports. This guide explains what the field is, what an evaluation involves, how it differs from a med spa, the red flags to watch for, and how to choose a physician you can trust.
What Does an Anti-Aging Doctor Actually Do?
An anti-aging doctor evaluates how your body is aging and works to slow age-related decline using measurable, evidence-based medicine. The work is diagnostic before it is prescriptive: a physician reviews your history, orders comprehensive labs, interprets your metabolic, inflammatory, and hormonal markers against your own baseline, and then builds an individualized plan. The aim is "healthspan" — feeling and functioning better, preserving strength, metabolic health, and cognition — not chasing a number on a clock.
This is general internal-medicine and preventive thinking applied to aging biology. It overlaps with cardiology, endocrinology, and metabolic medicine, and it leans heavily on the interventions with the strongest evidence: exercise, nutrition, sleep, and management of metabolic risk. At a longevity medicine practice, peptides, NAD+, and other tools are considered only after the foundations and the labs are in view.
What Does an Anti-Aging Evaluation Involve?
A legitimate anti-aging evaluation starts with a thorough clinical history and comprehensive bloodwork, then translates those results into a plan. It is a medical visit, not a sales appointment. The physician is looking for the modifiable drivers of accelerated aging — insulin resistance, chronic inflammation, hormonal shifts, poor sleep, and low cardiorespiratory fitness — because those are where intervention actually moves the needle.
- A detailed history: symptoms, medications, family history, and goals.
- Comprehensive labs — metabolic, inflammatory, and hormonal markers reviewed against optimal ranges.
- An honest discussion of what the evidence supports for your specific situation.
- An individualized plan that prioritizes lifestyle first, with medical interventions layered in only where warranted.
- Scheduled follow-up to re-test markers and adjust — because a plan without monitoring is just a guess.
How Is an Anti-Aging Doctor Different From a Med Spa?
A med spa sells cosmetic and wellness treatments; an anti-aging physician practices medicine. The difference is accountability and method. A med spa typically offers menu-driven services — facials, vitamin drips, off-the-shelf "packages" — often without baseline labs, medical history review, or a physician owning your outcome. An anti-aging doctor evaluates your physiology, prescribes based on data, monitors your response, and is licensed and accountable for the clinical decisions.
This is not a knock on aesthetics — it is a different category of care. If a service involves anything affecting your internal physiology, a physician should be evaluating you first. At LiveNow Longevity, every protocol is designed and overseen by Dr. Charles Kamen, MD, a board-certified neurologist.
Red Flags When Choosing an Anti-Aging Doctor
- Promises to "reverse aging" or guarantees of a specific outcome — honest medicine does not work this way.
- No baseline labs required before starting any protocol.
- Product is sold before any real evaluation — the visit is a transaction, not an assessment.
- No named, accountable physician — just rotating staff or an app-based questionnaire.
- No follow-up or monitoring built into the plan.
- Unclear sourcing for any prescribed compounds.
How Do I Choose a Good Anti-Aging Physician?
Choose for accountability and evidence, not marketing. Verify board certification through the American Board of Medical Specialties, confirm the physician holds an active state license, and make sure a named doctor — not an anonymous service — owns your care. Then assess the method: does the clinic require labs, individualize the plan, set realistic expectations, and schedule follow-up?
Dr. Kamen holds an MD from Albert Einstein College of Medicine, completed his internship at Yale-New Haven and his neurology residency at Loma Linda, and is board-certified by the American Board of Psychiatry and Neurology.

Frequently Asked Questions
Can an anti-aging doctor reverse aging?
No. No treatment reverses aging, and any clinic claiming otherwise has left evidence-based medicine. The honest goal is healthspan — extending the years you spend healthy and functional by slowing age-related decline with proven interventions.
Is an anti-aging doctor a real medical specialty?
Anti-aging or longevity medicine is an area of focus rather than a single board specialty. Look for a physician who is board-certified in an established specialty and who practices evidence-based, lab-driven preventive medicine — not a clinic built around selling products.
What is the difference between an anti-aging doctor and a med spa?
A med spa sells cosmetic and wellness services, often without labs or physician oversight. An anti-aging doctor evaluates your physiology, prescribes based on data, monitors your response, and is medically accountable for the decisions.
How much does an anti-aging evaluation cost?
At LiveNow Longevity the initial medical evaluation is $88, and it is applied toward your protocol if you continue care. Lab and treatment costs depend on your individual plan.
An anti-aging doctor is a physician who measures your biology and applies the interventions evidence actually supports — to help you feel and function better, not to sell a miracle. If you want a straight, physician-led assessment, explore longevity medicine at LiveNow Longevity or book the $88 evaluation with Dr. Kamen. He sees patients in Las Vegas at 9975 S Eastern Ave Ste 130 and offers telehealth for Nevada residents.
