Human skin cells and a reported reset of age markers
The creator describes a laboratory experiment in human skin cells: after temporary reprogramming, molecular age measurements reportedly fell by about 30 years. This is a claim about cultured cells and their markers, not people becoming 30 years younger. [1]

Temporary reprogramming of human skin cells
The creator describes work by Gill, Reik and colleagues at the Babraham Institute, published in eLife. Human skin cells called fibroblasts, from donors aged 38–53, were exposed to four Yamanaka factors for 13 days. According to the description, reprogramming was stopped before the cells completed the transition toward stem cells. The source presents this short exposure as the central feature of the experiment.

What the reported 30-year change measures
The description reports that measurements based on DNA methylation and gene activity assigned the treated cells a biological age about 30 years lower. Those measurements concern molecular markers in cultured cells. They do not show that a person became younger or lived longer. The creator also reports changes in collagen production and faster cell movement in laboratory wound-healing tests.

Retaining cell identity, with treatment still a prospect
According to the description, the cells regained their specialized skin-cell identity after reprogramming. It discusses possible future delivery methods and applications in skin repair and other tissues. These are proposed directions rather than demonstrated treatments in people. The description alone does not establish clinical safety or effectiveness.
