Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Polyphenols are a diverse group of naturally occurring compounds found in plants, such as fruits, vegetables, tea, and wine. Their use in skin care is supported by scientific evidence, primarily due to their antioxidant, anti-inflammatory, and photoprotective properties. Numerous in vitro and some in vivo studies have demonstrated that polyphenols can neutralize free radicals, reduce oxidative stress, and protect the skin from UV-induced damage, which are major contributors to skin aging and other skin conditions. Examples of well-studied polyphenols include flavonoids (e.g., quercetin, catechins), resveratrol, and epigallocatechin gallate (EGCG).

Clinical studies, though more limited, suggest that topical and oral applications of polyphenol-rich extracts can improve skin hydration, elasticity, and reduce the appearance of wrinkles. Green tea polyphenols, for example, have been incorporated into creams and serums with some studies reporting improved skin appearance and reduced UV-induced erythema. However, the evidence is not uniformly strong across all types of polyphenols, and many studies are preliminary or small-scale. There is also variability in outcomes depending on the source, concentration, and formulation of the polyphenols used.

Overall, while more large-scale, high-quality clinical trials are needed, there is moderate scientific support for the use of polyphenols in general skin care, particularly for their antioxidant and photoprotective effects.
