Vitamin E is often considered beneficial for the skin under the eyes. Its antioxidant properties can help protect the delicate skin in that area from damage caused by free radicals, which may contribute to premature aging and wrinkles. Vitamin E is also believed to have moisturizing properties that can help hydrate the skin and reduce dryness or flakiness. Additionally, it may have anti-inflammatory effects that can help reduce puffiness and soothe any irritation. However, it's important to note that individual results may vary, and it's always a good idea to do a patch test and consult with a dermatologist before using any new product on the delicate skin under your eyes.
