Dihydroquercetin Glucoside

Dihydroquercetin glucoside is a flavonoid compound—a type of plant polyphenol—derived from sources such as grapes and other botanicals. It functions as an antioxidant in skincare formulations, meaning it helps neutralise free radicals that can accumulate on and in the skin from environmental exposure, UV radiation, and oxidative stress.In cosmetic products, it serves a dual role: as an antioxidant that protects skin cells from damage, and as a skin conditioning agent that may help maintain the skin's appearance and resilience.

Dihydroquercetin glucoside operates by donating electrons to unstable free radical molecules, rendering them inert and preventing them from damaging skin cells. This process is particularly relevant in the context of UV exposure and environmental pollution, both of which generate reactive oxygen species (ROS) that can degrade collagen, impair skin barrier function, and accelerate visible signs of ageing.As a skin conditioning agent, it may also help maintain hydration and support the skin's structural integrity, though the specific mechanism in topical formulations requires further investig…

Dihydroquercetin glucoside is typically incorporated into serums, moisturisers, and protective products rather than used as a standalone treatment. It works well as part of a layered routine with other antioxidants (such as vitamin C or vitamin E) and broad-spectrum SPF, which together provide more comprehensive defence against environmental stressors. Apply products containing this ingredient to clean skin morning and evening, or as directed on the product label.

Dihydroquercetin glucoside is generally well-tolerated and considered safe for topical use in cosmetic products. No significant adverse effects or cautions have been widely reported, though those with known sensitivities to botanical extracts should patch-test first.
