Procyanidin C1 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. It stimulates collagen production, improving skin elasticity and reducing the appearance of wrinkles. As a result, it is commonly added to anti-aging creams, serums, lotions, and sunscreens.

In the nutraceutical sector, Procyanidin C1 is included in dietary supplements aimed at supporting cardiovascular health. It promotes healthy blood circulation, improves blood vessel flexibility, and helps maintain the integrity of blood vessels by strengthening capillary walls and reducing inflammation, potentially lowering the risk of hypertension and stroke.

Research also suggests a role in supporting the nervous system, potentially slowing brain degeneration and preventing neurological diseases such as Alzheimer's.

It also finds application in hair care products, where it supports scalp health and may help reduce hair loss by stimulating hair follicle activity and improving microcirculation in the scalp.

Due to its natural origin and low toxicity, Procyanidin C1 is favored in green and organic product formulations, offering a safe alternative to synthetic antioxidants and active ingredients.
