Resveratrol – Benefits, Side Effects & Uses

by ThankMeNow Editors on Sep 10, 2025
Resveratrol ($C_{14}H_{12}O_{3}$) is a potent phytoalexin—a protective antibiotic produced by plants (like red grapes and Japanese Knotweed) in response to environmental stress. In human skin, it is celebrated as a "longevity molecule" because it activates Sirtuins (SIRT1), specialized proteins that help coordinate cellular repair and promote cell survival. By upregulating the Nrf2 pathway, Resveratrol doesn't just neutralize external free radicals; it triggers the skin's own internal antioxidant production. This makes it an elite choice for reducing the "background noise" of chronic low-grade inflammation (often called "inflammaging") that leads to premature sagging and uneven tone.
