Enjoy a simple hot or cold compress-style relaxation routine with this reusable Gel Eye Mask. Depending on the actual product specifications, the flexible gel-filled mask may be cooled or gently warmed and placed over closed eyes for temporary comfort after work, travel or screen-heavy days. Exact gel formulation, outer material, dimensions, strap design, temperature limits and heating or cooling instructions vary by model and must be verified. Never microwave, boil or freeze the mask unless the manufacturer specifically permits that method. Test the temperature before placing it near the eyes and avoid extreme heat or cold that could injure delicate skin. If recommended, use a thin cloth barrier between the mask and skin. Stop immediately if you experience burning, numbness, pain or irritation. Inspect the pouch for leakage or damage before each use. This product is intended for relaxation and temporary temperature-based comfort only and should not be marketed as treating dark circles, migraines, eye disease, sinus conditions or other medical problems.
