Rating (out of 5): 2

Vitamin E, including beta-tocopherol (though alpha-tocopherol is more commonly studied), is frequently included in topical formulations aimed at reducing wrinkles and other signs of skin aging. The rationale is based on its antioxidant properties, which help neutralize free radicals generated by ultraviolet (UV) radiation and other environmental stressors that contribute to photoaging and wrinkle formation. Several in vitro and animal studies have demonstrated that vitamin E can reduce oxidative damage in skin cells, decrease inflammation, and possibly support skin barrier function. Some small clinical studies indicate that topical vitamin E (often in combination with other antioxidants, such as vitamin C) may improve skin texture and reduce the depth of wrinkles. However, the evidence for vitamin E alone—especially beta-tocopherol—is limited, with most research focusing on alpha-tocopherol or mixed tocopherols. Oral supplementation has not consistently shown significant benefits for skin aging or wrinkle reduction. Systematic reviews of anti-aging treatments generally conclude that while vitamin E has a plausible mechanism of action, the clinical evidence is modest and often methodologically weak. Thus, its use is primarily supported by preclinical data and a few small clinical trials, rather than large, high-quality human studies. Overall, the scientific basis for using vitamin E (including beta-tocopherol) to treat or prevent wrinkles is limited but present, justifying a moderate evidence rating.
