In the ever-evolving world of K-beauty, certain products come along and spark a skincare revolution. Lately, all eyes are on the numbuzin No.9 NAD+ BIO Lifting-sil Essence—a thread-like, futuristic formula that’s getting praise from skincare lovers, estheticians, and beauty editors alike. As a 37-year-old with mature, combination, slightly acne-prone skin, I’ve tried dozens of firming, hydrating, and anti-aging treatments, but this one? It doesn’t just feel innovative—it’s transformative.

Let’s break down why this essence has become a non-negotiable staple in my skincare routine, what makes it so special, and how it’s turning back the clock on my skin, one silky drop at a time.

Meet numbuzin: Skincare That Knows Your Number.

Before we get into the product, let’s talk about the brand. numbuzin is one of the most buzzed-about names in Korean skincare right now—and for good reason. The brand has a genius, user-friendly concept: instead of vague names, each product is labeled by a number (No.1, No.2, No.3, etc.), making it easier to create a customized skincare routine based on your skin concerns.

No.9 is their anti-aging, skin-lifting superstar—an essence designed specifically for wrinkles, sagging, and dullness. If your skin has started to lose firmness or elasticity (hello, 30s and beyond), this product was made for you.

Texture & First Impressions: A Serum-Essence Hybrid Unlike Any Other.

Let’s talk texture. The No.9 Essence doesn’t look or feel like your average essence. When dispensed, it forms a thread-like silk, almost like a spiderweb of hydration, that clings to your skin in the most satisfying way. It’s viscous but lightweight, and melts beautifully into the skin without any stickiness or residue.

When I first applied it, I instantly felt a soft tightening effect—not in a drying way, but in a “your skin is being hugged and lifted” kind of way. It absorbed quickly, layering well under both moisturizers and sunscreen.

This texture is perfect for those who love the weightlessness of an essence but want the power of a concentrated serum. It’s the best of both worlds.

What Makes It a Game-Changer: The Science Behind the Glow.

This is where the No.9 Essence really stands out. It’s packed with clinical-grade, anti-aging ingredients that go far beyond hydration.

NAD+ (Nicotinamide Adenine Dinucleotide).

Let’s start with the star: NAD+ is a coenzyme that naturally occurs in our bodies, but declines with age. In skincare, it’s a cellular energy booster that promotes skin repair, cell regeneration, and collagen production. It has been dubbed the “longevity molecule” for good reason—this ingredient literally tells your skin cells to act younger.

NAD+ helps:

• Improve skin texture and bounce.

• Speed up cell turnover (which is slower as we age).

• Reinforce the skin barrier.

• Revive dull, tired complexions.

If you’re serious about anti-aging, this is a next-level ingredient you want in your arsenal.

50 Types of Peptides.

Yes, fifty. These peptides work synergistically to stimulate collagen and elastin, smooth fine lines, firm sagging skin, and improve the skin’s structure over time. Think of peptides as messengers that tell your skin to behave like it did in your 20s.

This potent peptide cocktail targets all signs of aging, including:

• Deep wrinkles.

• Loss of elasticity.

• Sagging around the jawline and cheeks.

• Skin thinning.

The result? Plumper, firmer, more resilient skin that actually feels healthier.

Hydrolyzed Collagen & Adenosine.

These support and enhance the lifting effects. Hydrolyzed collagen helps boost suppleness and fill in fine lines, while adenosine is clinically proven to reduce the appearance of wrinkles.

My Experience: 4 Weeks to Rejuvenated, Lifted Skin.

I began using the No.9 Essence twice a day—morning and night—and immediately noticed a difference in how my skin felt.

Here’s how it went:

Week 1–2:

• My pores looked visibly smaller, especially around the nose and cheeks.

• Skin felt bouncier, especially in the mornings.

• There was a slight lifting effect, particularly around my smile lines and under the eyes.

• No breakouts or irritation (a huge win for acne-prone skin!).

Week 3:

• Skin texture became noticeably smoother, and makeup application was easier and more seamless.

• My cheekbones appeared more defined—something I haven’t seen since my late 20s.

• Fine lines around the eyes and forehead began to soften.

Week 4:

• The firmness in my jawline and neck became more prominent—like I had done a subtle at-home facelift.

• Overall brightness and clarity improved, and my skin looked more even and vibrant.

• Compliments from friends and family started rolling in: “You look so refreshed!” “Are you doing something new?”

At this point, I was using the essence along with the numbuzin No.9 Sheet Masks a few times a week, and the combo delivered an instant spa-like experience with long-lasting results.

You can use the No.9 Essence like a traditional essence or level it up as a targeted treatment:

• After toner, apply a generous amount of the essence all over your face.

• Add an extra layer to wrinkle-prone areas: forehead, eyes, smile lines, neck.

• Use lifting motions to massage the essence in until fully absorbed.

• Follow with your favorite moisturizer and SPF during the day.

Pro tip: You can also use this as a firming eye treatment—just tap gently around the orbital bone and watch it smooth crow’s feet and puffiness over time.

Who Should Try It?

The No.9 Essence is suitable for all skin types, but it’s especially ideal for:

• Aging or mature skin.

• Skin with visible fine lines or wrinkles.

• Loss of elasticity or sagging.

• Dull, tired, or textured skin.

• Anyone looking for a preventative anti-aging treatment.

If you’re in your 30s, 40s, or beyond, this is the kind of product that works with your skin’s natural repair process, not against it.

Clinically Proven Performance.

This essence isn’t just full of good intentions—it’s clinically tested to reduce the appearance of 11 types of wrinkles within just 4 weeks. These include:

• Forehead lines & frown lines.

• Crow’s feet & tear troughs.

• Bunny lines & lip lines.

• Smile lines & marionette lines.

• Mouth frown, chin wrinkles & neck lines.

It’s rare to find a product that targets so many specific areas with visible, proven results.

Final Verdict: The Anti-Aging Hero My Skin Needed.

There are a lot of lifting and firming products out there, but few deliver on their promises like the numbuzin No.9 NAD+ BIO Lifting-sil Essence. It’s more than just skincare—it’s science-meets-self-care in a silky, glow-boosting formula.

After one month, my skin looks more sculpted, lifted, radiant, and—dare I say—younger. It’s now a permanent step in my skincare routine, and I truly believe this essence is the kind of product that you’ll want to keep using long-term to preserve and enhance your skin.

Rating: 10/10. Would recommend to anyone starting to see signs of aging or looking to boost their skincare results dramatically.
