These hydrogel under-eye patches from Korean brand Petitfee are formulated with 24K gold and black pearl extract to help firm, brighten and hydrate the delicate under-eye area. The gel-based patches adhere closely to skin, delivering ingredients like sodium hyaluronate, adenosine, and plant extracts (green tea, aloe, cucumber) to visibly reduce puffiness, dark circles and fine lines. Each pack contains 60 pieces (30 pairs), enough for daily or twice-weekly use. Suitable for all skin types, they work well as a quick pick-me-up before makeup or a relaxing at-home spa treatment. To use, apply one patch under each eye, leave on for 15-20 minutes, then gently pat in the remaining essence. A popular choice among K-beauty fans for its cooling, plumping effect.
