This post is a paid collaboration with numbuzin
Today, I’m sharing my full review of numbuzin’s No.9 Sheet Mask and Essence, two innovative products I’ve been testing recently. If you’re already curious, you can find them here on Amazon. These two innovative skincare products promise to target fine lines, improve elasticity, and deliver an instant lifting effect. As someone always looking for effective skincare, I was thrilled when numbuzin reached out to collaborate on their No.9 line. This partnership was an easy yes, especially since their No.9 Essence had been on my wishlist for its peptide-packed formula. The opportunity to try it while supporting my blog felt like a win-win! So let’s dive into the products I’ve been incorporating into my skincare routine over the past month!
About numbuzin’s No.9 Line for Lifting & Anti-Aging
The numbuzin No.9 line works on improving skin firmness and elasticity. It’s geared and ideal for those concerned with wrinkles, fine lines, and sagging skin. People in their mid-30s and up will notice the most results and benefit from the products. Made to suit all skin types — but as always, if you know your skin is sensitive, use with caution and always patch test.
The hero ingredients in the No.9 line are NAD+ and a blend of 50 types of peptides. The peptides deeply nourish, plump, and help firm the skin, making the formula especially powerful for targeting visible signs of aging. In addition, the No.9 sheet mask contains dissolvable PLA threads that enhance the jawline and promote a radiant, plump complexion.
What is NAD+?
NAD+ (short for Nicotinamide Adenine Dinucleotide) is a molecule that naturally exists in our skin and body. You can think of it as fuel for our cells — it helps keep skin functioning well by repairing damage, boosting collagen production, and improving the skin’s ability to bounce back after stress.
As we age, our NAD+ levels decline, which can slow down cell turnover and lead to visible signs of aging. Applying NAD+ topically is believed to energize skin cells, support elasticity, and promote a more youthful appearance from the inside out.
What are peptides?
Peptides are short chains of amino acids — the building blocks of proteins like collagen, elastin, and keratin, which are essential for maintaining the skin’s structure and resilience.
In skincare, peptides function as messengers. They communicate with skin cells, signaling them to perform specific tasks, such as producing more collagen or improving cell repair processes.
In the numbuzin No.9 line, these peptides are carefully formulated to target key signs of aging, such as fine lines and loss of elasticity. By delivering these vital instructions directly to the skin, the mask encourages collagen production and enhances the skin’s natural ability to repair itself, resulting in a firmer, more youthful appearance over time.
What sets the numbuzin No.9 line apart isn’t just its powerful ingredients or innovative design — it’s also the price point. Compared to many other anti-aging and wrinkle-reducing products I’ve tried, these are incredibly affordable while still being high-performing.
The No.9 NAD+ Bio Lifting-sil Essence
I want to start with the numbuzin No.9 Essence, since it’s the one product for daily use — making it the product I’m most familiar with, and the one that helps maintain the results from the sheet mask over time. It’s a wrinkle-reducing and plumping serum that targets fine lines and wrinkles, and features 50 peptides, NAD+, and collagen-boosting ingredients that work together to smooth the skin and support the skin barrier.
My Experience with the No.9 Essence
I recently turned 34, and peptides have been on my radar for years. I’m happy to see that they’re becoming more popular and — most importantly —more affordable! The No.9 Essence from numbuzin is a great example of that.
Instructions say to apply it after toner, and the brand describes it as a “thread-like elastic essence,” which is spot on. The texture is similar to that of snail mucin, like a stretchy serum-cream hybrid. This one’s thicker than most serums, but not heavy. If anything, it feels like a comforting blanket that smoothes out the skin.
It’s fragrance-free and doesn’t have any particular scent to it, which I appreciate. I’ve been using two pumps every morning and on nights when I’m not using other actives. I also noticed and love the feature on the side of the bottle that shows how much product is left! So you’ll know when it’s time to stock up on more!
Despite the dry, cold weather lately, my skin has felt much softer and more resilient. I even noticed a stubborn forehead wrinkle — one I faded last year but saw return — has started to soften again since using this regularly for about a month. I have normal skin that leans dry in winter, and this essence leaves it feeling plump, smooth, and hydrated without stickiness.
If there’s one product I’d repurchase and want to keep in backup, it’s this one. I think anyone can enjoy it, but those in their 30s and up will especially appreciate and notice more the firming, smoothing, and moisture-locking benefits.
The No.9 NAD+ Bio Lifting-sil Full Face Mask
If you’re a fan of sheet masks, the No.9 Sheet Mask from numbuzin is one to try! It is a 3-part sheet mask designed to give your skin a natural facelift, reducing sagging and droopy skin. It comes with a top and bottom mask and an innovative lifting band.
- Top mask: Infused with NAD+ Bio capsules that support cell turnover, boost collagen production, and promote skin repair.
- Bottom mask: Contains dissolvable PLA threads to enhance jawline definition and improve skin firmness.
- Lifting band: Reusable and applies gentle compression to reinforce the sculpting effect.
My Experience with the No.9 Sheet Mask
Right off the bat, I loved the two-piece design of the No.9 sheet mask. The bottom half features ear loops, helping it hug the contours of your face and stay put — no slipping or sliding around. And the lifting band adds another layer of compression around the chin and neck area. A small neck extension is also included, which I really appreciate now that I’m noticing the first signs of sagging there.
This mask is drenched in essence — 48ml in total — so there’s plenty left over even after 20 minutes of wear. My hack when it comes to sheet masks is to always keep a few empty travel-sized bottles nearby. I like to pour the excess into one so I can reuse it later with dry sheet mask pods, thin toner pads, or just apply it like a regular serum throughout the week. It’s such a nice way to extend the experience and not waste product.
It’s a bit of a “mummy look” when you wear it — but honestly, kind of fun! I can absolutely see the appeal for younger people, but this mask feels more like a targeted treatment than your average hydration boost. After one use, my skin felt noticeably firmer, and my jawline was more defined. My skin also looked brighter. The snug yet comfortable lifting band made a visible difference — not quite a facelift, of course, but definitely gave a smoothing, sculpted effect!
I didn’t expect such instant results! This would be perfect before an event or when you want that lifted, well-rested appearance.
Final Thoughts
After a month of use, my overall experience with the numbuzin No.9 Essence and Sheet Mask has been fantastic. While I typically indulge in a sheet mask only a couple of times a year, this one definitely earned a spot in my routine for its instant plumping and sculpting effect — something I haven’t experienced with other sheet masks.
Although the “mummy look” with the lifting band might seem fun and gimmicky, especially for younger audiences, I don’t think it’s necessary for those in their twenties. The mask provides an instant decompression and slimming effect on the face, which could help reduce swelling. But the plumpness and reduction of sagging make it ideal for those concerned about wrinkles, fine lines, and loss of elasticity. In fact, I’m definitely repurchasing the sheet mask for my mom, who I know will love and benefit from it!
As for the No.9 Essence, I’m considering it a budget-friendly option for anyone who wants a high-performing peptide serum. This one truly hydrates, plumps, and smooths while also feeling barrier-strengthening. The Ordinary’s Multi-Peptide serum is another popular choice, but I do prefer this one as it’s a serum-cream hybrid. The texture feels more comforting and nourishing, making it perfect for dry skin, colder climates, or those who enjoy a creamy formula.
Whether you’re looking to firm up your skin, reduce fine lines, or try something innovative, the No.9 line is definitely worth checking out!
