Assessment Explanation
The claim links dietary intake to a biological mechanism (oxidative stress reduction) and a clinical outcome (photoaging), which is plausible and supported by mechanistic and observational studies. However, it implies a direct causal pathway that is difficult to isolate in humans due to confounders (e.g., overall diet quality, sun exposure, genetics). The verb 'reduces' is slightly definitive; 'may reduce' or 'is associated with reduced risk' would better reflect current evidence. No RCTs directly prove this exact pathway in humans over long-term photoaging outcomes.
More Accurate Statement
“Dietary intake of antioxidants from plant-based foods may reduce the risk of photoaging by mitigating oxidative stress and supporting skin integrity.”

Photoaging: Reversal of the Oxidative Stress Through Dietary Changes and Plant-Based Products
This study says eating plant-based foods can help protect your skin from sun damage by fighting harmful stress in your cells, which matches the claim that antioxidants from plants reduce wrinkles and skin aging.
Potential Role of Dietary Antioxidants During Skin Aging
This study says that eating antioxidant-rich plants like acai and moringa helps protect your skin from sun damage and aging, which is exactly what the claim says.
