A marketing phrase describing a product, treatment, or habit claimed to slow or mask visible signs of aging. It is not a clinical or scientific measure.

"Age-defying" shows up constantly in skincare, supplement, and wellness marketing, but it is a branding term, not a scientific one. No regulatory body defines what counts as age-defying, and the phrase says nothing about mechanism, dosage, or evidence.

That does not mean every age-defying product is meaningless. Some ingredients and interventions have real research behind them. It means the label itself should never substitute for looking at the underlying evidence.

The gap between age-defying marketing and age science is exactly where hype creeps in. When a product or headline uses this phrase, the useful question is not "does it work" but "compared to what, measured how, and over what timeframe." Age Life Forward reports on the science side of that question: biological age, healthspan, and prevention, not product claims.
