Q. What is regenerative skin treatment?
How does it work?

A. Regenerative skin treatment uses a cultivated sample of your own skin cells to visibly improve aging.

Regenerative skin treatment helps heal age-related problems like wrinkles by supplementing a cultivated sample of your own skin cells. With our cultivation technology even the smallest

sample can be cultivated up to a factor of 10,000. This makes regenerative skin treatment safe, easy and effective for our patients.

The cells we use for treatment are found in the inner layer of our skin (the dermis). These cells produce essential proteins like collagen, elastin and hyaluronic acid that help our skin keep its elasticity. But as we get older these cells naturally decrease, and by the time most of us reach 50 we’ll have only ⅓ of the healthy skin cells we had in our 20’s. This is why our skin gets wrinkled and saggy as we age.

Regenerative skin treatment helps reverse these effects of aging by using healthy cultivated skin cells to restore elasticity. We make sure to take the healthiest tissue samples possible for cultivation, usually from behind the ear where skin tends to be less exposed to UV damage.

Q. Why is regenerative skin treatment so effective?

A. Regenerative skin treatment is safe and natural because it uses your own cells to promote new tissue growth.

There are a lot of pros to regenerative skin treatment, but the biggest is probably the fact that treatment is done using only your own cells. This makes treatment safe and much more natural than conventional anti-aging treatments. Of course, like anything there are some negatives to regenerative medicine. Cell cultivation alone takes about a month, so the whole treatment process can be quite long. Even after treatment it can take 3-6 months to see improvement because collagen, elastin and hyaluronic acid need time to build up in your cells. Regenerative treatments might be more effective than conventional anti-aging, but you do need to be patient to see those results. But since regenerative medicine works to heal from the source, these results can last a long time.

Q. Where does cell cultivation happen?

A. We manage cultivation and cell storage at our own specialized Cell Processing Center.

At CellBank we have a specialized Cell Processing Center (CPC) where we carefully cultivate and store cells for regenerative treatment at clinics across the country. A facility like this is absolutely essential for our goal of making regenerative medicine safe and accessible.

Our CPC is fully accredited by the MHLW and operates 24 hours a day with the highest standards of sanitation and hygiene. When our Cultivation Specialists head into the cultivation room they must first wash their hands at the entrance of the facility, and after changing into two sets of sterile clothing they must pass through a sterile hallway to the center of the CPC to prevent any potential outside contamination. It’s a very complicated system.

We also provide clinics with total support to make sure regenerative treatments are available to anyone, anywhere. In 2020 we helped 14 clinics start their journeys in regenerative medicine.
