What's the best way to store the patches for maximum freshness and cooling effect?

Keep the sealed pouch in a cool, dry place away from direct sunlight and heat sources (like a bathroom radiator). Once opened, reseal the zip-lock tightly after each use to prevent the patches from drying out. For an extra depuffing boost, store the unopened pouch in the refrigerator — not the freezer — for at least 30 minutes before use. The cool temperature constricts superficial vessels temporarily, reducing the look of morning puffiness more noticeably than room-temperature patches. Avoid freezing, as ice crystals can rupture the hydrogel matrix and ruin the fit. Check the packaging for a period-after-opening symbol (usually 6M or 12M) and discard any patches that have lost their slip, turned cloudy, or smell off. If you travel, carry a few patches in a small zip bag with a cold pack for on-the-go refreshment.
