Resveratrol is a polyphenolic compound most famously found in the skin of grapes and in red wine. Its use in supporting or treating dermatitis is primarily based on preclinical scientific evidence rather than a strong tradition of historical use. Several in vitro and animal studies suggest that resveratrol possesses anti-inflammatory, antioxidant, and anti-microbial properties, all of which are potentially beneficial in the context of dermatitis, a skin condition characterized by inflammation and oxidative stress.

Resveratrol has been shown in experimental models to reduce the expression of pro-inflammatory cytokines and decrease oxidative damage in skin cells. Some studies have demonstrated that topical or systemic administration of resveratrol can ameliorate the symptoms of dermatitis in mice, including reduced erythema, edema, and histological markers of inflammation. The mechanisms proposed include inhibition of NF-κB signaling and suppression of inflammatory mediators such as TNF-α and IL-6.

Despite these promising findings, clinical evidence in humans is very limited. Only a few small-scale trials or case reports have investigated the effects of resveratrol-containing formulations on human skin conditions. Therefore, while the scientific rationale exists and preclinical data are encouraging, robust clinical validation is lacking. As such, resveratrol’s use for dermatitis cannot be considered evidence-based at this time, and it should be regarded as experimental, pending further research.
