The full review.
The under-eye area is the most demanding skin on your face. The skin is thinner, blood vessels sit closer to the surface, and late nights, allergies, or stress create dark circles and fine lines that concealer cannot fully hide. Most eye creams require massaging a pea-sized amount of product in for three seconds. Numbuzin’s No. 9 NAD+ Collagen Under Eye Patches use a different approach: they provide eight hours of coverage instead of seconds.
The overnight format is the advantage. Traditional eye patches last 15-20 minutes—barely enough time for a hydrogel to release active ingredients—but these patches maintain adhesion and steady-state delivery through an entire night’s sleep. The hydrogel matrix, made from carrageenan (Chondrus crispus) and agar, releases its actives over 6-8 hours, turning sleep into a treatment session.
Caffeine is the most immediate ingredient. Applied overnight, it works while fluid pooling and vascular dilation cause morning puffiness. By constricting small blood vessels beneath the thin under-eye skin, caffeine reduces the puffy, swollen appearance seen in the mirror each morning. The hydrogel patch’s cooling sensation amplifies this vasoconstrictive effect, making for an effective depuffing treatment.
Niacinamide and ascorbic acid (vitamin C) brighten the skin. Dark circles stem from vascular pooling, melanin deposition, or thin skin showing underlying structures; this duo addresses pigmentation. Niacinamide inhibits melanosome transfer to keratinocytes to even out periorbital hyperpigmentation, while vitamin C supports collagen synthesis and provides antioxidant protection. Consistent use shows a noticeable brightening effect over several weeks.
Hydrolyzed collagen provides immediate plumping. While topical collagen cannot replace structural collagen lost to aging (which requires deeper delivery), it acts as a humectant and film-forming agent to make the under-eye area look smoother and more taut. The overnight contact time allows more thorough absorption of these collagen peptides than a brief cream application.
The NAD+ and peptide complex extends the No. 9 line’s anti-aging approach to the eyes. Acetyl Tetrapeptide-5 (Eyeseryl) reduces periorbital puffiness. Acetyl Hexapeptide-8 (Argireline) relaxes the micro-expressions that cause crow’s feet. Palmitoyl Pentapeptide-4 (Matrixyl) signals collagen production. These peptides benefit from the extended contact time of an overnight application.
The patches are well-constructed. They contain embedded shimmer particles—calcium aluminum borosilicate and synthetic fluorphlogite—that give the hydrogel a subtle sparkle. This is cosmetic and provides a soft-focus brightening effect, adding K-beauty playfulness to the treatment. The shimmer can occasionally transfer to pillowcases.
Adhesion is vital for overnight patches, and these perform well. The hydrogel conforms to the under-eye contour and stays put during nighttime movement. To target the under-eye hollow and crow’s feet area simultaneously, angle the thin end toward the outer eye corner. They are comfortable enough to sleep in.
The formula is gentle for the sensitive periorbital area. It has no fragrance, no alcohol, and no essential oils. Allantoin and dipotassium glycyrrhizate (licorice root derivative) soothe inflammation. The pH is appropriate for the eye area. This formula respects the vulnerability of the skin.
Early reviews consistently report morning results: reduced puffiness, brighter under-eyes, and visibly plumped skin that helps concealer apply smoother. The immediate effect comes from hydration and caffeine. The long-term anti-aging benefits from the peptide and collagen complex require consistent weekly use for 4-8 weeks.
At $16.20 for 5 pairs ($3.24 per use), these are a reasonable price for premium eye patches. Used 2-3 times weekly as recommended, the monthly cost is $26-39—similar to a mid-range eye cream. The difference is the delivery format and contact time. Whether overnight patches outperform a daily eye cream depends on the specific cream and your consistency.
The box contains only five pairs, requiring frequent repurchasing for regular users. A subscription or larger box would improve the value.
These patches work best within the No. 9 system—using the NAD+ Lifting-sil Essence daily and the patches 2-3 times weekly creates a comprehensive anti-aging routine. However, they work as a standalone treatment for anyone wanting targeted overnight under-eye care with active ingredients rather than just moisture.

The science.
The Science
Caffeine works well for periorbital puffiness. A 2015 study in the Journal of Cosmetic Dermatology shows topical caffeine reduces under-eye puffiness via vasoconstriction and anti-inflammation. It inhibits phosphodiesterase, which increases cAMP levels and relaxes smooth muscle in blood vessel walls, lowering blood flow and swelling.
Acetyl Tetrapeptide-5 (Eyeseryl) is a targeted peptide in this formula designed for the periorbital area. Research in the International Journal of Peptide Research and Therapeutics shows it reduces eye edema by inhibiting glycation and improving lymphatic drainage. Clinical studies show a 32% reduction in eye puffiness after 60 days of use.
The carrageenan (Chondrus crispus) hydrogel delivery system creates an occlusive environment that increases transdermal penetration. The Journal of Drug Delivery Science and Technology shows hydrogel-based occlusive delivery increases active ingredient penetration by 2-5 times compared to non-occluded application, making overnight contact time functional for efficacy.
Niacinamide reduces dark circles by inhibiting melanosome transfer from melanocytes to keratinocytes, per a 2002 study in the British Journal of Dermatology. In the thinner skin of the periorbital area, this mechanism brightens skin over 8-12 weeks of consistent use.

Dermatologist Perspective
Dermatologists know thin periorbital skin benefits from extended-contact formats like overnight patches. Board-certified dermatologists note caffeine is a validated depuffing ingredient for the eye area; combining it with niacinamide and vitamin C manages dark circles. Hydrogel occlusion increases ingredient penetration, which matters for the naturally thinner eye area skin barrier. Dermatologists may recommend these patches as a supplement to retinoid-based eye creams for periorbital anti-aging.
Where it fits in your routine.
Cleanse and tone, then remove patches from each individual packet. Apply under each eye, angling the thin end toward the outer eye corner to cover the under-eye hollow and crow's feet area. Press gently so they adhere. Leave on overnight (6-8 hours). In the morning, remove patches and pat the remaining essence into the skin. Follow with your morning skincare routine. Use 1-3 times per week.
At $16.20 for 5 pairs ($3.24 per use), these patches cost little for premium K-beauty eye patches with this many ingredients. The per-treatment cost matches professional-grade eye masks from Western brands at one-third the price. But the small box size requires frequent repurchasing for regular users — monthly costs reach $26-39 at recommended frequency. These patches offer the best value for those using them 1-2 times weekly as a targeted treatment instead of daily.
Use this targeted overnight treatment if you have morning puffiness, dark circles, or under-eye fine lines. It works for people who find eye creams insufficient and want the extended delivery time of a hydrogel patch format.
The overnight format may not work if you rub your eyes at night or feel uncomfortable sleeping with patches on your face. Skip this if you need a daily-use product; at 5 pairs per box, this works best as a 1-3 times weekly treatment, not a daily staple.

The backstory.
These patches extend Numbuzin's No. 9 anti-aging line into targeted eye care, addressing the specific concerns of the periorbital area — puffiness, dark circles, crow's feet, and fine lines. The overnight format maximizes ingredient contact time during the skin's natural repair window, while the cooling hydrogel provides immediate depuffing.
About Numbuzin
Established Brand (5–20 years)Numbuzin launched in 2019 via Korea's Benow Inc. These eye patches apply the No. 9 NAD+ anti-aging line's peptide and NAD+ technology to the under-eye area in a hydrogel format for overnight use.
Common myths.
Eye patches can permanently eliminate dark circles.
Dark circles stem from multiple causes—genetics, vascular pooling, pigmentation, and thin skin—and no topical product permanently removes them. These patches provide temporary improvement using caffeine (vasoconstriction), niacinamide (brightening), and hydration (plumping), with cumulative benefits from consistent use.
Collagen in eye patches replaces collagen lost to aging.
Topical hydrolyzed collagen lacks the ability to penetrate deep enough to replace structural collagen in the dermis. It works as a humectant and film-forming agent to provide surface-level plumping and hydration. Peptides provide the anti-aging benefit by signaling the skin's own collagen production.
FAQ.
Can I wear these patches overnight?
Yes — these patches work overnight. The hydrogel matrix stays adhered and delivers moisture for 6-8 hours. Apply before bed and remove in the morning, then pat any remaining essence into the skin.
Do these patches help with dark circles?
These address dark circles in three ways: caffeine constricts blood vessels to reduce vascular-type dark circles, niacinamide and vitamin C brighten pigmentation-related discoloration, and hydration plumps thin under-eye skin. Results show most clearly with consistent use over several weeks.
How often should I use these eye patches?
Use 1-3 times per week based on your concerns. Once weekly works for maintenance. Use 2-3 times weekly to treat puffiness or dark circles faster. Each box contains 5 pairs.
Will the shimmer particles transfer to my pillowcase?
The patches contain cosmetic shimmer particles (calcium aluminum borosilicate, synthetic fluorphlogopite) that sometimes transfer. Use a dedicated pillowcase on patch nights, or apply the patches 30 minutes before bed so the surface sets.
Are these safe for sensitive eye area skin?
Yes — the formula is fragrance-free, alcohol-free, and uses soothing ingredients like allantoin and dipotassium glycyrrhizate. The hydrogel material is gentle and non-irritating. If you have very reactive periorbital skin, patch test on the inner forearm first.
