Procyanidin B5 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 contributes to premature aging. This compound supports collagen stability and may improve skin elasticity and firmness, making it a valuable ingredient in anti-aging creams and serums.

In hair care products, Procyanidin B5 promotes hair growth by stimulating dermal papilla cells in the scalp. Studies suggest it can prolong the anagen (growth) phase of hair follicles, making it effective in formulations targeting hair thinning and alopecia.

It is also utilized in dietary supplements aimed at supporting cardiovascular health. Its antioxidant action helps maintain healthy blood vessels by reducing oxidative damage and improving endothelial function. Additionally, Procyanidin B5 has been investigated for its potential anti-inflammatory and neuroprotective effects, indicating possible applications in functional foods and nutraceuticals designed for overall wellness and cognitive support.
