What specific ingredients in these patches help with the appearance of tired, dull eyes, and how do they work?

The efficacy of these patches relies on a blend of three key components designed to address dehydration and dullness. Sodium hyaluronate, a form of hyaluronic acid, has a strong affinity for water, helping to attract moisture to the upper layers of the skin and reducing the appearance of fine lines that can make the eye area look fatigued. Niacinamide (vitamin B3) helps reinforce the skin barrier and improves the look of uneven tone, which can make the under-eye area appear brighter and more rested over time. Additionally, blue agave extract provides plant-derived humectant and mineral components that help the skin hold onto moisture more effectively, reducing the feeling of tightness. Together, these ingredients focus on hydration and barrier support rather than heavy oils, making them suitable for those who prefer formulas built around skin-identical moisturizing components.
