Full Review
Sheet masks have a perception problem. For many Western skincare consumers, they're novelty items — fun for a self-care Sunday, photographed for Instagram, tossed after use. The Numbuzin No. 9 NAD+ BIO Lifting-sil Full Face Mask is trying very hard to change that narrative, and it brings genuinely interesting technology to the argument.
The concept is a three-part delivery system. The upper mask sheet contains NAD+ encapsulated in BIO capsules that release during the 30-40 minute wear time, along with the same multi-peptide complex found in the No. 9 Essence. The lower mask sheet — covering the jawline, chin, and lower cheeks — is embedded with dissolvable polylactic acid (PLA) threads that melt during wear, depositing a collagen-stimulating polymer directly onto the skin. And wrapping it all together is a physical lifting band that straps under the chin and over the head, providing mechanical compression to the lower face.
The PLA thread technology is the most novel element. Polylactic acid is well-known in aesthetic medicine — it's the active ingredient in Sculptra, an injectable filler that stimulates collagen production over months. Obviously, a sheet mask can't replicate what an injection achieves deep in the dermis. But the topical application creates a temporary firming film on the skin surface and may provide mild collagen-stimulating signals to the upper layers of the epidermis. It's borrowing from the clinic, not replacing it — and that distinction matters for setting realistic expectations.
The experience of using this mask is distinctly different from a standard sheet mask. The two-piece design requires a moment of orientation — the upper sheet covers forehead, eyes, and cheeks, while the lower sheet wraps around the jawline and chin. Once both pieces are applied, the lifting band straps on, creating a noticeable compression that holds everything in place. It feels like a gentle, sustained hug for your face. Not uncomfortable, but definitely present. You're aware you're wearing this in a way you wouldn't be with a regular sheet mask.
The 30-40 minute recommendation is longer than most sheet masks, and it's functional rather than arbitrary. The PLA threads need time to dissolve completely, and the extended contact time gives the NAD+ and peptide complex more opportunity to interact with skin cells. This isn't a product for the impatient — it's a commitment mask.
Removal reveals the immediate payoff. Skin looks noticeably firmer, more defined around the jawline, and plumped with hydration. The remaining essence absorbs quickly when patted in. There's a visible glow — a combination of increased hydration, the PLA film, and the lifting compression. The effect is temporary, lasting several hours to a day, but it's genuinely visible. For a pre-event treatment, this mask delivers.
The formulation itself mirrors the No. 9 Essence in ambition — NAD+, multiple peptides, five mineral ferments, resveratrol, hydrolyzed collagen, trehalose, panthenol, adenosine. It's a premium ingredient roster that would be impressive in a leave-on product, let alone a single-use sheet mask. Whether these actives have enough time to meaningfully penetrate during a 40-minute application is a fair question, but the extended wear time certainly helps compared to the 15-20 minutes of standard masks.
The mask material itself is well-constructed. It's soft, breathable, and stays in place without slipping — a common frustration with cheaper sheet masks. The fit covers the entire face including the often-neglected jawline area, which is specifically where aging signs like sagging and loss of definition appear first.
At $22 for four masks (roughly $5.50 per use), this is on the premium end for K-beauty sheet masks but dramatically cheaper than anything with comparable technology claims. A single Sculptra injection costs hundreds of dollars. Professional lifting facials run $100-300. This mask won't replicate those results, but it offers a consumer-accessible taste of the same ingredient philosophy.
The reusable lifting band is a nice touch — it survives all four sessions easily, reducing per-use waste. The packaging is individual foil packets that keep each mask fresh until use.
For consistent results, Numbuzin recommends using the mask 2-3 times per week alongside the No. 9 Lifting-sil Essence for daily use. At that frequency, a single box lasts about two weeks, and the monthly cost runs around $44 for the masks alone. That's a real investment, and whether the cumulative benefits justify it depends on how your skin responds to the peptide and NAD+ complex over time.
This mask is at its best as a weekly or twice-weekly intensive treatment within a broader anti-aging routine. It provides a visible immediate result that standard sheet masks can't match, and the technology behind the PLA threads and NAD+ capsules represents genuine innovation in the category. It doesn't replace professional treatments, but it democratizes the ingredients — and sometimes, that's enough.
Formula
Ingredients
The hero actives that drive this product's performance.
| Ingredient | Function | Evidence |
|---|---|---|
| Nicotinamide Adenine Dinucleotide (NAD+) | Delivered through encapsulated BIO capsules in the upper mask sheet, NAD+ aims to restore cellular energy production in aging skin during the extended 40-minute mask contact time, which provides significantly longer active ingredient exposure than a typical serum application. | emerging |
| 50-Type Peptide Complex (including Palmitoyl Tripeptide-5, Acetyl Hexapeptide-8, Copper Tripeptide-1) | The same comprehensive peptide library as the No. 9 Essence, but delivered through sheet mask soaking for extended skin contact. The 40-minute application time allows these signaling peptides more opportunity to interact with skin cells than a quickly-absorbing serum. | promising |
| Polylactic Acid (PLA) Threads | Dissolvable PLA threads embedded in the lower mask sheet dissolve during wear, depositing polylactic acid directly onto the jawline and lower face. PLA is used in cosmetic filler injections for collagen stimulation — this topical application aims to provide a temporary firming and lifting effect. | emerging |
| Hydrolyzed Collagen | Provides immediate plumping hydration and film-forming benefits that complement the physical lifting effect of the band and PLA threads. The extended mask contact time allows better absorption of collagen peptides into the upper epidermal layers. | promising |
| Niacinamide | Supports barrier function and provides brightening benefits during the mask session, contributing to the overall luminous, firmer appearance post-mask. | well-established |

Evidence
Science
The Science
Polylactic acid (PLA), the dissolvable thread material in the lower mask, has extensive medical and aesthetic use. In injectable form (Sculptra), PLA microparticles stimulate neocollagenesis — new collagen production — over 2-4 months. Research published in the Journal of Cosmetic and Laser Therapy (2004) demonstrated significant collagen I and III synthesis following intradermal PLA injection. However, topical PLA application from dissolving threads operates at the surface level, where the collagen-stimulating signal is limited to the epidermis rather than the deeper dermal layers that injections reach.
The extended mask contact time (30-40 minutes) represents a meaningful advantage for active ingredient delivery. Research published in Skin Pharmacology and Physiology has shown that sheet mask occlusion significantly enhances transepidermal penetration of active ingredients compared to non-occluded application. The hydrated, occluded environment created by the mask allows water-soluble actives like NAD+, peptides, and niacinamide to penetrate more effectively than they would from a quickly-absorbing serum.
Hydrolyzed collagen in this formula provides surface-level humectant and film-forming benefits. While topical collagen cannot penetrate to the dermis to replace lost structural collagen, a study in the Journal of Cosmetic Dermatology (2015) showed that hydrolyzed collagen peptides applied topically improved skin hydration and elasticity measurements, likely through moisture-binding and signaling effects on surface keratinocytes.
The mechanical compression from the lifting band may contribute to temporary lymphatic drainage, reducing facial puffiness. While no specific studies exist on this product's band, research on facial compression garments published in Aesthetic Surgery Journal has shown that external compression can reduce post-procedural edema and improve contour definition.

Dermatologist Perspective
Dermatologists view sheet masks as delivery vehicles rather than standalone treatments, and this mask's extended contact time and occlusive application improve ingredient penetration compared to wash-off products. Board-certified dermatologists note that topical PLA threads cannot replicate injectable PLA's dermal collagen stimulation, but acknowledge the ingredient's safety profile and surface-level benefits. The peptide and NAD+ complex is viewed with cautious optimism — the individual ingredients are interesting but unproven at these concentrations. Dermatologists may recommend this mask as a supplementary treatment for patients interested in non-invasive lifting approaches, with the caveat that professional treatments remain more effective.
Guidance
Usage Guide
How to Use
Cleanse and tone skin. Apply the upper mask sheet first, aligning eye and mouth openings. Apply the lower mask sheet, wrapping around jawline and chin. Secure the lifting band under the chin and over the head, adjusting tension for comfortable compression. Wear for 30-40 minutes. Remove mask pieces and lifting band. Pat remaining essence into skin — do not rinse. Follow with a light moisturizer if needed. Use 2-3 times per week for best results.
Value Assessment
At $22 for four masks ($5.50 per use), this is premium for K-beauty sheet masks but remarkably affordable for the technology claims. Professional lifting treatments cost 20-50 times more per session. The ingredient complexity — NAD+, PLA threads, 50 peptides, mineral ferments — would be impressive in a $100 product. A 16-sheet bundle is also available for better per-unit value. The main cost concern is frequency: at 2-3 uses per week, monthly mask expenditure alone is $44-66.
Who Should Buy
Anyone looking for an intensive weekly anti-aging treatment that provides visible immediate results for special occasions or consistent improvement over time. Ideal for those concerned about jawline definition and lower face sagging, and for K-beauty enthusiasts who appreciate technology-forward sheet mask innovations.
Who Should Skip
If you find sheet masks impractical or don't have 40 minutes for the full treatment, this won't work for your lifestyle. Also skip if you expect permanent lifting results — the effects are temporary without consistent use. Budget-conscious users should note the recurring cost at recommended frequency.

Background
The Why
This mask was designed as the intensive treatment companion to the No. 9 NAD+ Lifting-sil Essence, translating the same peptide and NAD+ technology into a format that delivers extended skin contact and adds physical lifting mechanics. The PLA thread technology borrows from aesthetic medicine, where polylactic acid fillers are used for collagen stimulation — here, it's applied topically through dissolvable threads in the mask material.

Myth vs. Reality
Myths
Myth
Sheet masks with lifting bands can permanently reshape your jawline.
Reality
The lifting effect from masks and bands is temporary — it comes from compression, hydration plumping, and the elastic tension of the band. There's no permanent structural change to facial contours. Consistent use may provide cumulative skin-quality improvements (firmness, elasticity), but not bone or fat-pad restructuring.
Myth
PLA threads in a sheet mask work the same as PLA filler injections.
Reality
Injectable PLA (like Sculptra) is deposited deep in the dermis where it stimulates long-term collagen production. Topical PLA threads dissolving on the skin surface cannot penetrate to the same depth. The effect is more superficial — providing a temporary firming film and mild collagen-stimulating signal at the surface level.
FAQ
FAQ
How long should I wear this mask?
Apply both mask pieces and the lifting band for 30-40 minutes. The PLA threads in the lower sheet need time to dissolve, and the peptide-NAD+ complex benefits from extended skin contact. After removal, pat the remaining essence into your skin rather than rinsing.
How often should I use this mask?
For best results, use 2-3 times per week. The box contains 4 mask sets, lasting 1-2 weeks of regular use. The lifting band is reusable across all four sessions.
Is the lifting effect permanent?
No — the immediate lifting and firming effect is temporary, lasting several hours to a day. It comes from hydration plumping, the PLA thread film, and compression from the band. Consistent use over weeks may improve skin firmness and elasticity through the peptide and NAD+ complex.
Can I use this mask with the No. 9 Lifting-sil Essence?
Yes — they're designed as companions. Use the essence daily and the mask 2-3 times weekly for a comprehensive anti-aging routine. On mask days, use the mask in place of the essence, not on top of it.
What are PLA threads and are they safe?
Polylactic acid (PLA) is a biodegradable polymer used in medical sutures and cosmetic fillers. In this mask, PLA threads are embedded in the lower sheet and dissolve during wear, depositing a thin film on the skin. Topical PLA is safe and non-irritating — it's the same material used in dissolvable medical stitches.
