Singer and actress Noriko Sakai (53) updated her Instagram on the 4th, posting a photo of herself undergoing a "fibroblast cell culture transplant," a type of anti-aging treatment.

Sakai posted a photo on Instagram of herself undergoing treatment at a clinic in Tokyo. She explained, "Fibroblast cell culture transplant. A treatment in which my own fibroblast cells are cultured billions of times using my own blood as food and then returned to my skin. The ultimate natural anti-aging treatment. All I have to do is multiply my own cells and return them," and revealed, "In May of this year, they took a large amount of my blood to feed on, so I was able to culture a sufficient amount! Finally, I have transplanted it into the dermis with a vital injection!"

As a result of the treatment, she explained, "For about a week from the day of the treatment, depending on the person, injection marks may remain, but they improve day by day, and can be hidden with makeup. On my hands, they were no longer visible after three days." She continued, "It's so wonderful to be able to look forward to my future self! I can change myself and my future. Haha, beauty isn't achieved in a day... I only live once. I decided to take on the challenge in order to discover the version of myself I love!"

This post has received many praises such as "You're getting more and more beautiful, you're a beauty queen," "You'll always be beautiful," and "Your sense of beauty and drive are amazing." However, one of the photos she posted was a shocking shot of her with bright red spots all over her face, which has also resulted in some concerned comments such as "You have reddish spots, but will they itch or get worse?" and "Are you okay? I hope your skin goes back to beautiful."
