Antioxidant ingredient
Hydrolyzed Proanthocyanidin
Hydrolyzed Proanthocyanidin is a hydrolyzed form of proanthocyanidin (condensed tannins / oligomeric proanthocyanidins, OPCs), typically sourced from grape seed, maritime pine bark, or bilberry. Hydrolysis reduces polymer chain length, improving bioavailability and skin penetration. Proanthocyanidins are exceptionally potent antioxidants with documented MMP-inhibitory and collagen cross-linking activity, making them effective anti-aging and skin-firming actives beyond simple radical scavenging.
Also known as: hydrolyzed OPC, hydrolyzed oligomeric proanthocyanidin

Benefits
- ✓Hydrolysis of polymeric proanthocyanidins (condensed tannins from grape seed, pine bark, or bilberry) produces oligomeric/monomeric forms with dramatically improved skin penetration compared to intact high-molecular-weight tannins
- ✓Proanthocyanidins are among the most potent natural antioxidants — free radical scavenging activity is 20× greater than vitamin C and 50× greater than vitamin E in some assays
- ✓Inhibit collagen-degrading metalloproteinases (MMP-1, MMP-3) and cross-link collagen and elastin fibers, providing direct structural support for skin firmness and anti-aging activity
No known watch-fors.
Compatibility
✓ Works well with
+ Tocopherol+ Ascorbic Acid+ Resveratrol+ Niacinamide
