Hydrogel eye patches use a different physical format than traditional paper or cellulose sheet masks. The hydrogel material is a semi-solid, jelly-like substance that can hold a high concentration of watery essence. When applied, it conforms closely to your skin's contours—especially important around the delicate, curved eye area—creating an occlusive barrier. This barrier minimizes evaporation, allowing the active ingredients to absorb more effectively into the upper skin layers during the 15–20 minutes of wear.
While regular sheet masks cover larger areas and often have less precise fit, hydrogel patches target specific zones with minimal movement or slippage. The cooling sensation many people notice comes from the moisture-rich hydrogel contacting warm skin. For DIZAO Gold "TIGU" patches, this essence includes a blend of snail mucin (to help retain moisture), allantoin (to soothe potential roughness), and chamomile (for a calming effect). Because the hydrogel traps the liquid against your skin, you get more prolonged contact with these ingredients compared to simply applying a serum or cream.
After removing the patches, you'll notice the skin looks temporarily smoother and more hydrated—the hydrogel's main cosmetic benefit. For best results, gently press any remaining essence into your skin and follow with your usual moisturizer or eye cream to seal in the hydration.
