Procyanidin A1 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. Its ability to support collagen stability makes it valuable in anti-aging formulations, where it contributes to improved skin elasticity and reduced appearance of wrinkles.

In dietary supplements, Procyanidin A1 is included for its potential cardiovascular benefits. It supports vascular health by enhancing endothelial function and reducing oxidative damage in blood vessels. Research also suggests anti-inflammatory and neuroprotective effects, making it a compound of interest in products aimed at cognitive health and metabolic wellness.

Additionally, Procyanidin A1 is studied for its role in promoting hair growth, as it may extend the anagen (growth) phase of hair follicles. This has led to its inclusion in some hair care products targeting thinning hair or scalp health.
