COSRX 5-PDRN Collagen Under-Eye Patches — 60 Hydrogel Patches for Brightening & Hydration

COSRX 5-PDRN Collagen Eye Patches are hydrogel under-eye masks infused with five types of PDRN, peptides, vitamin C, glutathione, and multiple hyaluronic acids to help refresh, hydrate, and visibly brighten the under-eye area.

These single-use hydrogel patches deliver a concentrated 5-PDRN serum formulated from salmon-derived and biotechnological sources, designed to sit snugly along the orbital bone to target the look of tiredness and uneven tone. Each jar contains 60 patches (30 pairs) made from a dense, serum-rich hydrogel that releases active ingredients while providing a cooling, clinging fit for easy at-home use.

How do these patches help reduce the appearance of dark circles and dullness?

The patches combine five varieties of PDRN with vitamin C and glutathione, targeting uneven pigmentation and the appearance of shadowed under-eye areas. The hydrogel base locks in moisture to improve the look of texture and radiance instantly after application.

• 5-PDRN complex sourced from salmon, botanical, and microbial origins
• Vitamin C and glutathione support brighter-looking skin tone
• Serum-rich hydrogel delivers concentrated actives directly to under-eye skin
• Designed for spot treatment — applied where darkness is most noticeable

What makes the hydrogel formula different from regular eye creams?

Unlike creams that sit on the surface, hydrogel patches are solidified with 85 g of serum per container to provide occlusive delivery and a cooling contact that maximizes ingredient absorption. The patch shape contours to the under-eye so active ingredients remain in place without smearing.

• Hydrogel adheres to under-eye contours for focused delivery
• Occlusive effect improves transdermal contact of actives
• Leaves behind excess serum that can be massaged into surrounding skin
• Can be used under makeup prep or as an express refresh

Are these eye patches suitable for sensitive skin?

COSRX formulates these patches with naturally derived colorants and tests for irritation; a clinical report cited a significant reduction in redness after one use. Still, because the area is delicate, a patch test is advised if you have a history of sensitivities to active ingredients.

• Color derives from natural ingredients, not synthetic dyes
• Irritation testing reported reduced redness after a single application
• Patch test recommended for reactive skin types
• Gentle removal and post-use massage help minimize tugging

How and when should I use these patches for best results?

Apply to a clean, dry face and place a patch under each eye for at least 10 minutes; longer wear is fine if desired. After removing the patches, pat or massage any remaining serum into the under-eye and surrounding cheek area to extend hydration and benefit from leftover actives.

• Use after cleansing and before heavier creams or oils
• Leave on for 10 minutes or longer for intensified treatment
• Massage residual serum into skin instead of rinsing off
• Use 2–3 times weekly or as a targeted pick-me-up

Who is this for: These COSRX 5-PDRN Collagen Eye Patches are aimed at anyone looking to boost under-eye hydration, temporarily brighten the appearance of dark circles, or add a quick, non-invasive treatment into their skincare routine. They suit those who prefer targeted hydrogel treatments over creams, people wanting a quick de-puff and glow before events, and skincare users seeking a serum-dense option formulated with multiple hyaluronic acids, peptides, and antioxidant actives. If you have extremely reactive skin, consider a patch test first to confirm compatibility.
