Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Polyphenols are a diverse group of naturally occurring compounds found in plants, including fruits, vegetables, tea, and wine. Their use for supporting or treating wrinkles is primarily based on scientific research, although the evidence is still emerging and not robust. Polyphenols possess antioxidant properties, which can help protect the skin from oxidative stress caused by ultraviolet (UV) radiation—a key factor in skin aging and wrinkle formation. In vitro and some animal studies have shown that polyphenols, such as those from green tea (epigallocatechin gallate), grapes (resveratrol), and other sources, can protect against collagen degradation, reduce inflammation, and increase skin hydration and elasticity.

Some small clinical studies have found that topical or oral polyphenol formulations may improve skin texture and reduce the appearance of wrinkles. For example, randomized controlled trials with green tea polyphenol extracts have reported modest improvements in skin elasticity and reduction in wrinkle depth. However, these studies often use specific, standardized extracts rather than "unspecified" polyphenols, and results are not always consistent. Overall, while there is a scientific rationale for the use of polyphenols in skin aging, the clinical evidence—especially for unspecified polyphenols—is limited and not definitive. More large-scale, high-quality human studies are needed to confirm their efficacy for wrinkle reduction.
