The Claim
In human dermal fibroblasts exposed to hydrogen peroxide, treatment with creatine or nicotinamide does not reduce cellular senescence, as assessed by beta-galactosidase activity and SASP cytokine levels, indicating that these compounds do not reverse established senescence in this in vitro model.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
After skin cells are damaged, taking creatine or a form of vitamin B3 doesn’t seem to help them recover or become less aged, based on lab tests.
See the scientific wording
Creatine or nicotinamide treatment after hydrogen peroxide exposure is not associated with reduced senescence in human dermal fibroblasts, as measured by beta-galactosidase activity and SASP cytokine levels, indicating these agents do not reverse established senescence in this model.
What the research says
1 studyStudy: Creatine and Nicotinamide Prevent Oxidant-Induced Senescence in Human Fibroblasts
The study found that giving creatine or nicotinamide *after* hydrogen peroxide damage didn’t help fix the aged cells, which matches the claim.
