"When I decided to undergo regenerative therapy for a nagging injury, I put the word out to people I trust to direct me to the best of the best. Harry Adelson, N.D. was the name that kept coming back to me."
Ben Greenfield
Author, Health & Fitness Coach
"I attribute a great deal of the fact that I'm 43 and really do feel like I did, possibly better than I did, when I was 18 years old to the idea of continual rejuvenation with protocols like this. Stem cell therapy is anincredible thing."
Carrie Diulus, M.D.
Orthopedic Spine Surgeon
"As a Cleveland Clinic trained orthopedic spine surgeon, when I heard about regenerative injections being performed into intervertebral discs and epidurals, I had to see it with my own eyes. When I visited and watched Dr. Adelson operate, what I discovered was pleasantly surprising. Dr. Adelson is a skilled spine injector, practices flawless sterile technique, is honest and upfront, and is completely professional. I'm happy to call Dr. Adelson a trusted colleague and a friend."

After aesthetic stem cell injections, post-care is simple but important to support healing and optimize results. Stay hydrated and avoid alcohol for at least 24 hours post-treatment. Skip makeup, saunas, and intense workouts for 24-48 hours to reduce infection risk. Wear sun protection for several months following facial microneedling. Your provider will recommend a personal plan based on your treatment type and needs.
It can take 8 to 12 weeks or more to see results from stem cell therapy for joint pain. Results take place gradually. Unfortunately, some individuals do not respond to therapy.
We recommend starting the eligibility and consultation process to determine if we can help support your personal health needs.
Stem cell therapy and regenerative medicine can be very effective. Although some people don't respond to therapy, those who do frequently describe the benefits as less pain, improved daily function, and better quality of life.
