Resveratrol
A stilbene polyphenol with the broadest mechanism profile in the complex. Sirtuin activation, UV resilience, anti-inflammation, and direct antioxidant activity ÔÇö from a single molecule.
What is Resveratrol?
Resveratrol (3,5,4′-trihydroxystilbene) is a polyphenol produced naturally by certain plants as a defence mechanism against stress, UV radiation, and pathogens. Our Resveratrol is extracted from Polygonum Cuspidatum root ÔÇö a source that provides the highest natural concentration of the compound with consistent purity across batches. It was first studied extensively in the context of cardiovascular health and longevity research, where its sirtuin-activating properties attracted significant scientific interest. In dermatology, those same mechanisms translate to UV resilience, inflammation control, and cellular longevity at the skin level.
Sirtuin activation and skin longevity
Sirtuins (SIRT-1 through SIRT-7) are a class of protein that regulate cellular stress responses, inflammation, and longevity. SIRT-1, the most studied, is activated by caloric restriction and by Resveratrol. In skin cells, SIRT-1 activation modulates the activity of p53 ÔÇö the tumour suppressor protein that triggers apoptosis in UV-damaged cells. By regulating p53, Resveratrol helps the skin manage UV-induced damage more efficiently: damaged cells are repaired rather than lost, reducing the long-term erosion of the dermal cell population that manifests as visible aging.
COX-2 inhibition and inflammation
Resveratrol is a selective inhibitor of the COX-2 (cyclooxygenase-2) enzyme, which is responsible for producing prostaglandins ÔÇö the pro-inflammatory signalling molecules responsible for UV-induced redness, the inflammatory cascade that degrades collagen, and the chronic low-grade inflammation that accelerates aging. This anti-inflammatory mechanism makes Resveratrol particularly valuable for skin that is frequently UV-exposed, environmentally stressed, or constitutionally reactive.
Synergy with Superoxide Dismutase
SOD and Resveratrol provide complementary antioxidant coverage at different stages of the radical cascade. SOD neutralises superoxide before it forms hydrogen peroxide. Resveratrol scavenges hydrogen peroxide (the product of SOD activity) and other ROS, and it does so via a different mechanism (direct radical scavenging rather than enzymatic catalysis). Together, they provide substantially broader antioxidant protection than either alone ÔÇö a synergism that has been independently studied and confirmed in the context of photoprotection.
