Procyanidin B4 is widely used in the cosmetic and skincare industry due to its strong antioxidant properties. It helps protect the skin from oxidative stress and environmental damage, particularly from UV radiation, which can accelerate aging. As a result, it is commonly added to anti-aging creams, serums, and lotions to improve skin elasticity and reduce the appearance of wrinkles. In dietary supplements, procyanidin B4 supports cardiovascular health by promoting healthy blood circulation and helping maintain blood vessel integrity. It is also studied for its potential to reduce inflammation and support metabolic health, making it a candidate for functional foods and nutraceuticals aimed at overall wellness. Additionally, its natural origin and bioactive profile make it valuable in natural and organic product formulations, where synthetic additives are avoided. Research is ongoing into its neuroprotective effects, suggesting future applications in cognitive health supplements.
