Hydrolyzed Proanthocyanidin

Hydrolyzed proanthocyanidin is a polyphenolic compound derived from plant sources such as pomegranate, sorghum, and camu-camu fruit. It belongs to a class of flavonoids known for their antioxidant properties. The hydrolyzed form means the larger molecular structures have been broken down into smaller units, potentially improving skin penetration and bioavailability.In skincare formulations, hydrolyzed proanthocyanidin functions as an antioxidant to neutralise free radicals, whilst also providing emollient and humectant properties that support skin hydration and barrier health.

Hydrolyzed proanthocyanidins work primarily through free radical scavenging. Free radicals are unstable molecules generated by UV exposure, pollution, and natural cellular processes. These compounds donate electrons to stabilise free radicals, preventing them from damaging skin cells and collagen.The humectant and emollient properties operate through different mechanisms: humectants absorb water from the environment and deeper skin layers to plump the outer layer, whilst emollients form a lightweight protective film that reduces transepidermal water loss.

Hydrolyzed proanthocyanidin is typically used in serums, moisturisers, and treatment products at concentrations that support antioxidant and conditioning benefits. It works well alongside other antioxidants such as vitamin E or vitamin C, though formulation chemistry should be considered to ensure stability. Use daily as part of your routine for consistent protective benefits.

Generally well-tolerated and suitable for most skin types. As with any ingredient, perform a patch test if you have known sensitivities to plant-derived polyphenols.
