Can I use these patches on areas other than under my eyes, and what's the best way to do it?

According to the product information, these hydrogel patches are designed for the delicate under-eye area but are not limited to it. They can also be placed on the forehead or other small facial zones that look tired or dehydrated and need a smoother, more rested appearance. The hydrogel base provides a flexible fit that conforms to these areas.

For best results, start with clean, dry skin. Gently remove a patch from its backing and apply it, smoothing it down to ensure good contact. The gel texture helps it adhere without sliding. It can be used as a short prep step before makeup or an event, or as part of an evening skin ritual when you want focused hydration without a full face mask. Pay attention to your skin's response, especially if applying to new areas. Do not apply to broken or damaged skin, and discontinue use if you experience any stinging, redness, or persistent discomfort.
