Expert Verdict

Endogenous polyamine that induces autophagy, the cellular self-cleaning mechanism degrading damaged organelles. Endogenous spermidine levels correlate inversely with biological age. Declining autophagy with age is partly attributable to falling polyamine levels. Topical application is an active research area with emerging clinical data in skin.
