What Is the Numbuzin No. 9 NAD+ Retinol Volumetox Eye Cream?

The Numbuzin No. 9 NAD+ Retinol Volumetox Eye Cream is a Korean skincare product that targets multiple signs of aging around the eyes. It comes in a compact 10ml tube with a precise pump dispenser. The brand Numbuzin organizes its products by number. The No. 9 line focuses specifically on anti-aging, lifting, and firming.

This eye cream is a cream-serum hybrid. It combines the richness of a cream with the lightweight feel of a serum. The formula features NAD+ (Nicotinamide Adenine Dinucleotide), a coenzyme that supports collagen production and cellular repair. It also packs retinol, 50 types of peptides, niacinamide, ceramide NP, and hyaluronic acid.

Numbuzin markets this product as a solution for dark circles, fine lines, wrinkles, puffiness, sagging, and under-eye hollowness. That is a long list of promises. But the ingredient list backs up those claims with clinical-grade actives that have proven track records in skincare science.

The cream has a pearlescent finish that gives a subtle glow to the under-eye area right after application. It launched as a standout product in the K beauty space and quickly gained attention on platforms like TikTok, Reddit, and YouTube.

Key Ingredients in Numbuzin No. 9 Eye Cream

The ingredient list of this eye cream reads like a skincare dream. Let me break down the star ingredients that make this formula stand out from standard eye creams on the market.

NAD+ (Nicotinamide Adenine Dinucleotide) sits at the core of this formula. NAD+ is a coenzyme found in every living cell. It plays a critical role in energy metabolism, DNA repair, and cellular aging. As we age, NAD+ levels decline. This eye cream delivers it topically to support skin repair and collagen synthesis.

Retinol (0.5%) is one of the most studied anti-aging ingredients in dermatology. It boosts cell turnover, smooths fine lines, and improves skin texture. The 0.5% concentration in this cream strikes a balance between effectiveness and gentleness for the delicate eye area.

50 Types of Peptides form the backbone of this formula. These include well-known peptides like Palmitoyl Tripeptide-1, Acetyl Hexapeptide-8, and Copper Tripeptide-1. Peptides signal the skin to produce more collagen and elastin. They also help reduce puffiness and firm sagging skin.

4% Niacinamide brightens dark circles and evens out skin tone. Ceramide NP strengthens the skin barrier and locks in moisture. Hyaluronic acid provides deep hydration and plumps the skin from within.

How Does Numbuzin No. 9 Eye Cream Feel on the Skin?

Texture matters a lot with eye creams. The skin around your eyes is the thinnest and most sensitive skin on your face. A product that feels too heavy or too thin will not deliver the best results.

The Numbuzin No. 9 Eye Cream has a rich yet lightweight consistency. It looks pearlescent in the tube. Once you dispense it, it feels smooth and slightly creamy between your fingers. It spreads easily without tugging on the skin.

Many users describe it as a “cream-serum hybrid.” It does not sit on top of the skin like thick eye creams. It absorbs within seconds and leaves a subtle dewy finish. That pearlescent quality gives your under-eyes an instant brightening effect even before the active ingredients start working.

The pump dispenser is a smart design choice. It controls the amount of product you use per application. A single pump gives you enough for both eyes. This also keeps the formula hygienic since your fingers never touch the product inside the tube.

After absorption, the skin feels soft, plump, and hydrated. There is no sticky or greasy residue. You can easily apply makeup on top without any pilling or balling up. This makes it a great option for both morning and nighttime routines.

Who Should Use Numbuzin No. 9 Eye Cream?

This eye cream works for a wide range of skin types and concerns. Numbuzin states it is suitable for all skin types, and user reviews largely confirm this claim.

If you struggle with fine lines and crow’s feet, the retinol and peptides in this formula can help smooth those out over time. People dealing with dark circles will benefit from the niacinamide and NAD+ combination that brightens and energizes the under-eye area.

Those with puffy eyes or under-eye bags will appreciate the depuffing peptides like Acetyl Tetrapeptide-5. Users with sagging or loss of firmness around the eyes will find value in the 50 peptides that promote collagen and elastin production.

However, if you have never used retinol before, start slowly. Apply this cream every other night for the first two weeks. This lets your skin adjust to the retinol without irritation or flaking. Once your skin builds tolerance, you can increase to nightly use.

People with extremely sensitive skin or active eczema around the eyes should do a patch test first. The retinol content, while moderate, can cause mild tingling or redness for very reactive skin types.

Top 3 Alternatives for Numbuzin No. 9 NAD+ Retinol Volumetox Eye Cream

How to Apply Numbuzin No. 9 Eye Cream Correctly

Proper application makes a big difference with eye creams. The right technique ensures maximum absorption and prevents unnecessary irritation.

Step 1: Cleanse your face and apply your toner and serum first. The eye cream should go on after thinner products but before heavier moisturizers.

Step 2: Pump a small amount onto your ring finger. The ring finger applies the least pressure, which is ideal for the delicate eye area.

Step 3: Dot the cream along the orbital bone under your eye and on the outer corners. Do not apply it directly on your eyelid or too close to the lash line. The product will naturally migrate slightly as it absorbs.

Step 4: Gently tap and pat the cream into your skin. Avoid rubbing or dragging motions. Tapping promotes circulation and helps the product absorb without stretching the skin.

Step 5: For a boosted effect, Numbuzin recommends pairing this cream with the No. 9 Eye Patches. Apply the patches over the areas where you placed the cream. This combination creates an occlusion effect that pushes the active ingredients deeper into the skin.

Use this cream twice daily for best results. Apply it in the morning under makeup and at night as part of your PM routine.

Clinical Results and What to Expect

Numbuzin conducted clinical testing on this eye cream. The results showed visible improvement in five types of eye wrinkles within just four weeks. These wrinkles include crow’s feet, under-eye lines, deep lines between the eyes and cheeks, inner-eye lines, and upper eyelid wrinkles.

The clinical data also showed that the cream restores volume and elasticity to hollow under-eye areas. It visibly reduces dark circles, hyperpigmentation, and discoloration for a brighter, more refreshed appearance.

In the first week, most users notice improved hydration and a subtle brightening effect. The pearlescent finish gives an instant glow. This immediate payoff keeps you motivated while the long-term actives work beneath the surface.

By week two or three, the retinol and peptides begin showing their effects. Fine lines start to look softer. The skin around the eyes feels firmer and more resilient. Puffiness tends to decrease as the depuffing peptides accumulate their benefits.

The four-week mark is where the most dramatic changes appear. Crow’s feet look smoother. Dark circles appear lighter. The overall eye area looks more youthful and rested. Consistency is key. Skipping applications will delay your results.

Numbuzin No. 9 Eye Cream: Pros and Cons

Every product has strengths and weaknesses. Here is an honest look at both sides of the Numbuzin No. 9 Eye Cream.

The pros are impressive. The ingredient list is loaded with active ingredients like NAD+, retinol, 50 peptides, niacinamide, and ceramide. Few eye creams pack this many actives into one formula. The texture absorbs fast and works well under makeup. The pump dispenser keeps the formula fresh and hygienic.

The clinical backing adds credibility. The product does not rely on vague marketing claims alone. It has tested data showing improvements in five types of wrinkles within four weeks. The price point is also reasonable for a K beauty product with this level of formulation.

On the downside, the tube is only 10ml. Heavy users may find themselves running out quickly. The retinol content, while moderate, can cause mild irritation for very sensitive skin types or retinol beginners. Some users reported mild tingling during the first few applications.

The pearlescent finish is a pro for most people. But if you prefer a completely matte finish, this might not suit your preference. Also, while the cream works for all skin types, people with very oily eyelids may find the finish slightly dewy.

How Does It Compare to Other K Beauty Eye Creams?

The K beauty market has many strong eye cream options. So how does Numbuzin No. 9 stack up against the competition?

Compared to the Beauty of Joseon Revive Eye Serum, Numbuzin No. 9 offers a richer formula with more peptides. Beauty of Joseon uses retinal (a stronger vitamin A derivative) but has a simpler overall formula. Numbuzin wins on ingredient variety and anti-aging depth.

Against the COSRX Advanced Snail Peptide Eye Cream, Numbuzin takes a more aggressive anti-aging approach with retinol and NAD+. COSRX focuses more on hydration and repair through snail mucin. If your main concern is aging, Numbuzin has the edge. If hydration is your priority, COSRX may serve you better.

Compared to Western options like the RoC Retinol Correxion Eye Cream, Numbuzin provides a more sophisticated peptide blend. RoC keeps things simple with retinol and minerals. Numbuzin offers 50 peptides, NAD+, ceramide, and niacinamide on top of retinol.

The price-to-performance ratio of Numbuzin No. 9 is strong. You get a clinically tested, multi-active formula at a price that sits comfortably in the mid-range category.

Real User Reviews and Feedback

User feedback across platforms like Amazon, Reddit, and TikTok paints a mostly positive picture of this eye cream.

On Reddit, users in the r/koreanskincare community praise the formula for its peptide-rich composition. One user shared that layering the essence on fine lines makes the skin feel “plump and hydrated.” Others noted visible improvement in dark circles after consistent use for three to four weeks.

TikTok reviewers highlight the texture and instant brightening effect. Several skincare influencers and even dermatologists have reviewed this product positively. One reviewer noted that the consistency is “perfect, rich but easy to apply” and that the eye area felt well-hydrated immediately.

On Amazon, the product has earned solid ratings. Users appreciate the pump dispenser, fast absorption, and visible results. Common praise points include reduced puffiness, softer fine lines, and brighter under-eyes.

The most common complaint is the small 10ml size. Some users feel the product runs out too fast given the price. A few reviewers with sensitive skin reported mild tingling during the first week, which typically subsided as their skin adjusted.

Is Numbuzin No. 9 Eye Cream Worth the Price?

The Numbuzin No. 9 Eye Cream retails for around $15 to $21 depending on where you buy it. The official Numbuzin website often runs promotions that bring the price down further.

For the quality of ingredients in this formula, the price is competitive. Many Western eye creams with fewer actives cost two to three times as much. The inclusion of NAD+, retinol, 50 peptides, niacinamide, and ceramide in one product provides excellent value for money.

The 10ml tube lasts about four to six weeks with twice-daily use. That works out to roughly $3 to $5 per week for a clinically tested eye cream. Compared to premium eye creams from brands like La Mer, Sulwhasoo, or Estée Lauder, this is a fraction of the cost with comparable or superior ingredient lists.

If you are on a tight budget, the Beauty of Joseon Revive Eye Serum offers a solid alternative at an even lower price. But if you can stretch to the Numbuzin price point, the extra peptides, NAD+, and clinical backing make it a worthwhile investment.

Tips for Getting the Best Results

Getting the most out of this eye cream requires more than just applying it. Here are some practical tips to maximize your results.

Be consistent. Use the cream twice daily without skipping. The active ingredients need time to build up in your skin. Sporadic use will give you sporadic results.

Start slow with retinol. If you are new to retinol, use this cream every other night for the first two weeks. This prevents irritation and flaking. Gradually increase to nightly use as your skin adjusts.

Always wear sunscreen. Retinol makes your skin more sensitive to UV rays. Apply a broad-spectrum SPF 30 or higher every morning. This protects your under-eye area and prevents the retinol from working against you.

Store it properly. Keep the tube in a cool, dark place. Retinol degrades with exposure to light and heat. The pump dispenser helps, but proper storage extends the product’s effectiveness.

Pair it with the right products. Avoid using other strong actives like vitamin C or AHAs directly around your eyes at the same time as this cream. Layering too many actives can overwhelm the delicate skin and cause irritation.

How Long Before You See Results?

Patience matters with any skincare product. The Numbuzin No. 9 Eye Cream delivers results on two timelines.

The immediate effects are visible right after application. The pearlescent formula gives your under-eyes a subtle glow and brightened appearance. The hydrating ingredients like hyaluronic acid and glycerin plump the skin instantly. You will notice your under-eye area looks fresher and more awake within minutes.

The long-term results take more time. Most users report noticeable changes in fine lines and dark circles around the three to four week mark. This aligns with the clinical test data from Numbuzin. Retinol needs about four weeks of consistent use to show its full effect on cell turnover and wrinkle reduction.

Peptide benefits accumulate gradually. By weeks six through eight, the firming and volumizing effects become more pronounced. The under-eye area feels fuller, and sagging starts to improve.

For best results, commit to at least eight weeks of consistent use before making a final judgment. Some users see dramatic improvements sooner. Others with deeper wrinkles or more stubborn dark circles may need a full two to three months.

Final Verdict on Numbuzin No. 9 Eye Cream

The Numbuzin No. 9 NAD+ Retinol Volumetox Eye Cream is a strong performer in the crowded eye cream market. It combines a thoughtful blend of NAD+, retinol, 50 peptides, niacinamide, ceramide, and hyaluronic acid into one formula.

The texture is pleasant. The absorption is fast. The clinical data is encouraging. Real user reviews across multiple platforms confirm that the product delivers visible results for dark circles, fine lines, puffiness, and loss of firmness.

At its price point, this eye cream offers exceptional value. You get professional-grade ingredients in a well-designed package. The pump dispenser keeps the formula stable and hygienic. The 10ml size is the only real drawback, and even that is standard for K beauty eye creams.

If you are looking for a multi-tasking eye cream that addresses multiple signs of aging without breaking the bank, the Numbuzin No. 9 Eye Cream deserves a spot on your vanity. It earns a strong recommendation for anyone serious about their under-eye care.

Can I use Numbuzin No. 9 Eye Cream in the morning?

Yes, you can use this eye cream both morning and night. The formula absorbs quickly and sits well under makeup. Just remember to apply sunscreen over it during the day. Retinol increases sun sensitivity, so UV protection is essential for morning use.

Yes. The formula contains 4% niacinamide that brightens dark circles and evens out skin tone. NAD+ supports cellular repair, and the pearlescent finish gives an instant brightening effect. Clinical tests showed visible reduction in dark circles and hyperpigmentation within four weeks.

Can I layer other products over Numbuzin No. 9 Eye Cream?

Yes. Apply the eye cream after your toner and serum but before your moisturizer. It layers well with most skincare products. Avoid using strong actives like vitamin C or AHAs directly on the eye area at the same time to prevent irritation.

Is retinol in eye cream safe to use around the eyes?

Retinol is safe for use around the eyes at appropriate concentrations. The 0.5% retinol in this formula is moderate and well-suited for the eye area. Apply it along the orbital bone and not directly on the eyelid or lash line. The product naturally migrates slightly as it absorbs.
