Oxidative Stress | ORAC 10,700 – neutralizes lipid peroxides | ORAC 55,653 – superior radical scavenger [⁵] |
Moisture Barrier | Repairs ceramide-deficient pores et peau | Seals moisture loss (TEWL ↓ 32%) [⁶] |
UV Injury Restaurer | Reduces MMP-1 enzyme (collagen destroyer) | Minimal direct DNA restaurer exercice |

6. Way forward for Plant-Principalement basé Anti-Vieillir
Soulèvement analyse révèle shea unsaponifiables pourrait upregulate Voie Nrf2 (mobile protection) equally to ergothioneine [¹], alors que cocoa polyphenols activate sirtuins (longevity proteins) like PQQ [⁸].
