To undergo cultured stem cell therapy, blood and skin tissue are first taken, and the stem cells contained within are extracted and cultured.
Cultivation takes approximately one month, after which the stem cells can be administered via intravenous infusion. The infusion is administered slowly over approximately 40 to 60 minutes.
The skin is harvested under local anesthesia, and the sensation is similar to that of dental treatment. The harvested area is small, approximately 5mm, and the scars become almost invisible after about one month.
