COSRX 5-PDRN Complex Collagen Hydrogel Eye Patches — 60 Under-Eye Patches, Vitamin C & Hyaluronic Acid for Dark Circles

COSRX 5-PDRN Complex Collagen Gel Eye Patches are hydrogel under-eye masks infused with five sources of PDRN, Vitamin C, peptides and multiple hyaluronic acids to target the look of dark circles, uneven tone and dehydration.

These Korean skincare hydrogel patches deliver a concentrated serum-backed sheet specifically shaped for the under-eye area. Each patch contains a solidified 5-PDRN serum base combined with antioxidant and moisturizing ingredients to help the under-eye zone appear brighter, plumper and more even in texture. The set contains 60 patches (30 pairs) for repeated at-home treatments.

How do these patches work on dark circles and uneven tone?

The patches sit directly on under-eye skin to transfer a high-concentration serum blend where it’s needed most, combining vitamin C, glutathione and a multi-source PDRN complex. This multi-ingredient approach supports visible radiance and helps even-looking tone without abrasive action.

• 5-PDRN complex sourced from salmon, botanicals and microbes for targeted delivery
• Vitamin C and glutathione for antioxidant support and brighter-looking skin
• Hydrogel carrier maximizes serum contact and absorption

What results can I expect after one treatment?

After a single 10-minute application you can expect skin to look more hydrated and the under-eye area to appear fresher. Clinical testing cited reduced redness after one use; regular use can help maintain a more rested appearance and smoother surface texture.

• Immediate hydration and a plumped look from hyaluronic acids
• Visible reduction in surface redness reported in testing
• Noticeably smoother under-eye texture after application

How do I use the COSRX 5-PDRN eye patches safely and effectively?

Apply patches to clean, dry skin and leave them on for 10 minutes or longer if desired. Remove gently and pat any remaining serum into the skin; no rinsing required. A patch test on the body is recommended 24 hours before full facial use to check sensitivity.

• Step 1: Cleanse and dry the under-eye area thoroughly
• Step 2: Place patches along under-eye contour for 10+ minutes
• Step 3: Remove and massage remaining serum; discard patch

Are these patches suitable for sensitive skin?

The formula avoids artificial colorants and uses naturally derived ingredients for tint; it has undergone irritation testing and showed reduced redness in clinical evaluation. Still, individual sensitivity varies, so follow the recommended patch test and discontinue use if irritation occurs.

• No artificial colorants; tint comes from natural ingredients
• Irritation-tested with reported reduction in redness after one use
• Patch test advised; consult a physician if adverse reactions appear

Who is this for: These COSRX 5-PDRN Complex Collagen Gel Eye Patches are aimed at anyone looking to target temporary under-eye dullness, dehydration, and uneven tone without invasive treatments. They suit users who want a quick at-home refresh—ideal for busy mornings, pre-event prep, or as a weekly boost for tired-looking under-eyes. If you have very reactive skin or known allergies to seafood-derived ingredients, perform the recommended patch test or check with your healthcare provider before use.
